C24.10 - Specifications, Guides and Practices

SIGNIFICANCE AND USE
5.1 The old saying “A chain is only as strong as its weakest link” is very applicable to a SSG system. In reality, a SSG system, to be successful, must establish and maintain a chain of adhesion. For example, a factory applied finish must adhere adequately to a metal framing member, a structural glazing sealant to that metal finish, that structural glazing sealant to a reflective coating on a glass lite, and lastly, that reflective coating to a glass surface. This guide will assist in the identification and development of, among others, performance criteria, test methods, and industry practices that should be implemented to obtain the required structural glazing sealant adhesion and compatibility with other system components.  
5.2 Although this guide has been arranged to permit easy access to specific areas of interest, it is highly recommended that the entire guide is read and understood before establishing the requirements for a particular SSG system.  
5.3 This guide should not be the only criteria upon which the design and installation of a SSG system is based. The information herein is provided to assist in the development of a specific program with a goal of achieving a successful SSG system installation. Information and guidelines are provided for the evaluation, design, installation, and maintenance of a SSG system and many of its various components. Considering the range of properties of structural glazing silicone sealants, as well as the many types of framing system designs, material combinations that can be used, various material finishes, and the many types and varieties of accessories, the information contained herein is general in nature.  
5.4 Generally, the design, fabrication, and installation of a SSG system requires more technical knowledge and experience then is required for a conventionally glazed window or curtain wall system. To ensure the success of a SSG system, it is important that suppliers, fabricators, and installers of materials an...
SCOPE
1.1 Structural sealant glazing, hereinafter referred to as SSG, is an application where a sealant not only can function as a barrier against the passage of air and water through a building envelope, but also primarily provides structural support and attachment of glazing or other components to a window, curtain wall, or other framing system.  
1.2 This guide provides information useful to design professionals, manufacturers, contractors, and others for the design and installation of a SSG system. This information is applicable only to this glazing method when used for a building wall that is not more than 15° from vertical; however, limited information is included concerning a sloped SSG application.  
1.3 Only a silicone chemically curing sealant specifically formulated, tested, and marketed for structural sealant glazing is acceptable for a SSG system application.  
1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. SI units in this guide are in conformance with IEEE/ASTM SI 10.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Note 1: Currently, there is no ISO standard similar to this specification.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This standard specification covers the basic requirements for cylindrical sealant backing for use with cold liquid-applied sealants. Cylindrical sealant backings are classified into three types: type C, type O, and type B, composed predominantly of closed cell material, open cell material, and bi-cellular material, respectively. Test methods for cylindrical sealant backing include water absorption, density, outgassing, compression deflection and recovery, and tensile strength. The sealant shall be clean, free of scale, foreign matter, oil, or water.
SIGNIFICANCE AND USE
5.1 This specification is designed to give some indication as to the differences in performance for various cylindrical sealant backings.  
5.2 Although this specification qualifies a cylindrical sealant backing for use, it does not address the compatibility of the backing with the sealants with which it will make contact. Sealant compatibility should be confirmed by the sealant manufacturer. Compatibility characteristics of sealants in contact with cylindrical sealant backings can be determined by Test Method C1087.
SCOPE
1.1 This specification covers the basic requirements for cylindrical sealant backing to be used with cold liquid applied sealants for use in building seals.  
1.2 Cylindrical sealant backing serves one or more of the following functions:  
1.2.1 Limits the amount and depth of sealant applied into a joint,  
1.2.2 Acts as a bond breaker to allow joint movement without undue stress to the sealant,  
1.2.3 Provides a form to assist the sealant in developing the proper shape factor, and  
1.2.4 Acts as a barrier to the flow of sealant through the joint.  
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTM committees or other organizations.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Importance of Prequalification—For required accuracy of test results and reliability of certification, it is essential that testing laboratories be prequalified. This practice establishes those qualifications.  
4.2 Contractual Relationships:  
4.2.1 Although testing laboratories may be qualified in accordance with this practice, it is important for the contracting authority to consider the relationship of the testing laboratory with other interested parties before engaging the laboratory to perform the testing. The other interested parties in the project usually consist of the manufacturer of the material to be tested, the contractor (bidder), the owner of the project (user and contracting authority), and the architect who serves as the owner's agent in preparing the contract documents.  
4.2.2 Many sealant manufacturers have their own qualified testing facilities that are used to conduct research and maintain quality control of their products. Generally, the companies that have such facilities are willing to certify as to the performance standards with which their products comply. The contracting authority should determine if there are conflicting interests in such a relationship. The contracting authority may prefer that the product testing to ascertain conformance with specific performance standards and the reporting of such testing be performed by a qualified but independent testing laboratory. The contract documents should make this requirement known so that bidders can bid accordingly.  
4.2.3 The testing of each caulking and sealant for each and every project can be costly. On a small building project, the cost of testing, if required, may be more than the cost of the sealant materials. On a large project, on the other hand, the cost of testing a sealant with accompanying certification by a qualified independent testing laboratory may be small in comparison to the sealant materials and commensurate with the assurances desired by the contracting auth...
SCOPE
1.1 This practice describes the qualifications, including minimum requirements for personnel and equipment, duties, responsibilities, and services of independent commercial materials testing laboratories engaged in the testing of caulking and sealants used in building construction.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This guide provides information and guidelines for consideration by the designer or applicator of a joint seal. It explains the properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures such as, substrate cleaning and priming, and installation of the components of a sealed joint. It presents guidelines for the use and application of the various materials, design of a sealant joint for a specific application, and environmental conditions and effects that are known to detrimentally affect a sealant joint. The information and guidelines are also useful for those that supply accessories to the sealant industry and for those that install sealants and accessory materials associated with sealant use.  
4.2 In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for its products and their proper use and installation. Considering the range of properties of commercially available sealants, the variety of joint designs possible, and the many conditions of use, the information contained herein is general in nature.  
4.3 It should be realized that a sealant and sealant joint are expected to have a design life during which they remain functional. However, a sealant and sealant joint will also have a service life. The intent is for service life to meet or exceed design life. There are many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacent materials, installation techniques or deficiencies, sealant joint design (or lack thereof), proper maintenance (or lack thereof), and environmental exposure, among others. The designer of a joint seal should take the above into consideration when designing and specifying sealants for certain applications.  
4.4 The design life of a sealant or sealant joint should be considered in conjunction with the design life of the structure for which it is us...
SCOPE
1.1 This guide describes the use of a cold liquid-applied sealant for joint sealing applications. Including joints on buildings and related adjacent areas, such as plazas, decks, and pavements for vehicular or pedestrian use, and types of construction other than highways and airfield pavements and bridges. Information in this guide is primarily applicable to a single and multi-component, cold liquid-applied joint sealant and secondarily to a precured sealant when used with a properly prepared joint opening and substrate surfaces.

ABSTRACT
This specification describes the properties of one-component solvent release sealants for use in building construction. These sealants are generally formulated to withstand a specified maximum joint movement in extension and compression of the nominal joint width. The sealants shall be tested, and is expected to conform to the following physical properties: extrudability after aging, shore A hardness, indentation hardness, bubbling, adhesive and cohesive loss after cyclic movement, slump, stain index, tack-free time, and accelerated weathering (edge cracking, center cracking, adhesion loss, and color change).
SIGNIFICANCE AND USE
6.1 This specification describes solvent release sealants for general caulking and sealing operations in building construction. However, it should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates and that there is no implication that the sealants are equivalent in all physical properties.  
6.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
SCOPE
1.1 This specification describes the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5 % in extension and 7.5 % in compression of the nominal joint width.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Design professionals, for aesthetic reasons, have desired to limit the spacing and width of sealant joints on exterior walls and other locations of new buildings. Analysis of the performance factors and especially tolerances that affect a sealant joint is necessary to determine if a joint will have durability and be effective in maintaining a seal against the passage of air and water and not experience premature deterioration. If performance factors and tolerances are not understood and included in the design of a sealant joint, then the sealant may reach its durability limit and failure is a distinct possibility.  
4.2 Sealant joint failure can result in increased building energy usage due to air infiltration or exfiltration, water infiltration, and deterioration of building systems and materials. Infiltrating water can cause spalling of porous and friable building materials such as concrete, brick, and stone; corrosion of ferrous metals; and decomposition of organic materials, among other effects. Personal injury can result from a fall incurred due to a wetted interior surface as a result of a failed sealant joint. Building indoor air quality can be affected due to organic growth in concealed and damp areas. Deterioration is often difficult and very costly to repair, with the cost of repair work usually greatly exceeding the original cost of the sealant joint work.  
4.3 This guide is applicable to sealants with an established movement capacity, in particular elastomeric sealants that meet Specification C920 with a minimum movement capacity rating of ±121/2 %. In general, a sealant with less than ±121/2 % movement capacity can be used with the joint width sizing calculations; however, the width of a joint using such a sealant will generally become too large to be practically considered and installed. It is also applicable to precured sealant extrusions with an established movement capacity that meets Specification C1518.  
4.4 The intent of this guide is to...
SCOPE
1.1 This guide provides information on performance factors such as movement, construction tolerances, and other effects that should be accounted for to properly establish sealant joint size. It also provides procedures to assist in calculating and determining the required width of a sealant joint enabling it to respond properly to those movements and effects. Information in this guide is primarily applicable to single- and multi-component, cold-applied joint sealants and secondarily to precured sealant extrusions when used with properly prepared joint openings and substrate surfaces.  
1.2 Although primarily directed towards the understanding and design of sealant joints for walls for buildings and other areas, the information contained herein is also applicable to sealant joints that occur in horizontal slabs and paving systems as well as various sloped building surfaces.  
1.3 This guide does not describe the selection and properties of joint sealants (1)2, nor their use and installation, which is described by Guide C1193.  
1.4 For protective glazing systems that are designed to resist blast and other effects refer to Guide C1564 in combination with this guide.  
1.5 This guide is not applicable to the design of joints sealed with aerosol foam sealants.  
1.6 For structural sealant glazing systems refer to Guide C1401 in combination with this guide.

ABSTRACT
This specification describes the properties of applied, flat shaped precured elastomeric silicone joint sealants that bridge joint openings and are adhered to joint substrates utilizing a liquid applied silicone adhesive sealant to seal building openings such as panel joints, metal flashing joints, or other building openings in place of conventional liquid applied sealants. Seals are applied in three different configurations, as follows: as a bridge joint, the seal is applied flat on the surface to cover a joint opening; as a beveled bridge joint, the seal is applied on the beveled edge of a substrate to bridge a joint opening.; as a U-joint, the seal is applied in a U-configuration within a joint. Seals are classified into Movement Classes on the basis of movement capability, and Tear Class on the basis of tear propagation. Seals should adhere to specified requirements as to stability, color and texture, application, adhesion and cohesion, and movement, modulus, and tear characteristics.
SCOPE
1.1 Precured elastomeric silicone joint sealants, hereinafter referred to as seal, are manufactured in flat, cured, extruded shapes and are primarily used to span joint openings in construction. This specification describes the properties of applied, flat shaped precured elastomeric silicone joint sealants, hereinafter referred to as applied seal, that bridge joint openings and are adhered to joint substrates utilizing a liquid applied silicone adhesive sealant, specified by the manufacturer, hereinafter referred to as adhesive to construction substrates, to seal building openings such as panel joints, metal flashing joints, or other building openings in place of conventional liquid applied sealants.  
1.2 Seals are applied in three different configurations:  
1.2.1 As a bridge joint, the seal is applied flat on the surface to cover a joint opening. See Fig. 1.
FIG. 1 Bridge Joint Configuration  
1.2.2 As a beveled bridge joint, the seal is applied on the beveled edge of a substrate to bridge a joint opening. See Fig. 2.  
FIG. 2 Beveled Bridge Joint Configuration  
1.2.3 As a U-joint, the seal is applied in a U-configuration within a joint. See Fig. 3.
FIG. 3 U-Joint Configuration  
1.3 This specification is for a flat extruded shape.  
1.4 An applied seal meeting the requirements of this specification shall be designated by the manufacturer as to movement class and tear class as described in Section 5.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Walls, ceilings, and floors in building construction with improperly sealed joints, voids, or penetrations will not achieve the desired sound transmission loss. Proper sealing of joints, voids, and penetrations will increase sound transmission loss by reducing airborne sound flanking paths.
SCOPE
1.1 This practice provides information for the use of sealants to reduce sound transmission characteristics of interior walls, ceilings, and floors by proper application of sealants to joints, voids, and penetrations normally found in building construction, which are commonly referred to as airborne sound flanking paths.  
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This standard does not purport to address fire stopping or safing requirements for joints, voids, and penetrations through fire-rated wall, ceiling, and floor assemblies. Additional requirements may be necessary for fire-rated assemblies to meet the applicable building code provisions.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Guidelines are provided for the use of silicone sealants in protective glazing. Protective glazing incorporates various forms of glazing that are not covered in Guides C1401 and C1193. The requirements for a sealant in protective glazing are similar to the requirements for structural sealant glazing. However, for certain applications, such as missile impact and blast resistant glazing, sealant requirements may be greater. Modes of failure for blast resistant glazing can be different than the modes of failure for missile impact glazing. Of particular concern is the outbound glazing support loading from blast wave negative phase pressure or the dynamic rebound of the glazing, or both.  
4.2 Many types of protective glazing systems are relatively new and the test methods and standards for protective glazing are continually evolving. Because the demands on a sealant in protective glazing systems are changing, guidelines are necessarily general in many instances.  
4.3 As a component of a glazing system, the sealant can be a factor in whether a glazing system meets the requirements of a specific test method but other factors such as the frame and glazing type, may be of greater influence.  
4.4 The designer of a protective glazing system should consult with the various manufacturers of the component materials. The experience and judgment of the glazing system designer working with the sealant manufacturer and other component manufacturers, can ultimately determine whether a specific glazing system will successfully meet a specific test requirement.
SCOPE
1.1 This guide covers the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural hazards, such as hurricanes, earthquakes, windstorms, impacts from wind-borne debris; and assaults such as burglary, air blasts, forced-entry attacks and ballistic attacks.  
1.2 While other glazing accessories and components are used in protective glazing, this document specifically describes the use of silicone sealants for protective glazing systems.  
1.3 This guide provides information useful to design professionals, architects, manufacturers, installers, and others for the design and use of silicone sealants for protective glazing systems.  
1.4 A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for protective glazing must successfully integrate the frame and its anchorage, glass, or other glazing materials, protective film or interlayer and silicone sealant into a high performance system. Compliance with code or other requirements can be determined through physical testing of the glazing system or through computer simulation.  
1.5 Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and airblast test requirements incorporate the use of silicone sealants specifically formulated, tested, and marketed for this application. Sealants that are commonly used today comply with Specifications C920 and C1184.  
1.6 This guide does not discuss sealants intended to protect against radioactivity or provide biological containment.  
1.7 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade ...

SIGNIFICANCE AND USE
4.1 Guidelines are provided for the procedures to evaluate existing SSG installations, including two- and four-sided installations. Due to the unlimited range of materials that may be used in a particular building, the information contained in this guide is general in nature. For a discussion of new SSG installations, refer to Guide C1401.  
4.2 Typical conditions are listed that might be discovered during, or suggest the need for, such evaluations. Guidelines are also suggested for times to perform evaluations. These guidelines are also necessarily general. Professional judgment of a qualified person should be used in determining the appropriate time to perform an evaluation on a particular building.  
4.3 This guide should not be the only reference consulted when determining the scope of a proposed evaluation. For example, the local building code and the manufacturers' product literature for the actual materials used (if known) should also be considered.  
4.4 This document is not a substitute for experience and judgment in assessing the condition of the specialized types of construction discussed.
SCOPE
1.1 The existing condition of SSG installations should be periodically evaluated in-situ to detect if problems exist, and if so found, to address them before they become severe or pervasive. Evaluation of existing SSG installations is required by certain building codes and local ordinances. This guide provides a program to evaluate the existing conditions, lists typical conditions that may exist, and suggests times when such evaluations are appropriate. Presently, only a silicone sealant that is specifically formulated, tested and marketed as a structural glazing sealant is allowed for structural sealant glazing. The committee with jurisdiction over this standard is not aware of any comparable standards published by any other organizations.  
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 The intent of this guide is to provide the reader with information concerning possible reasons for paint failures where the paint is used over a latex sealant.
SCOPE
1.1 This guide describes the practical considerations that may be used to determine the compatibility of a paint or coating to be applied over a latex sealant or caulk. It evaluates the appearance and not the performance characteristics of the coated or painted joint.  
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 The guide provides recommendations for substrates and methods of surface preparation to be used in comparative tests of building seals and sealants.
SCOPE
1.1 This guide describes the recommended standard substrates and their recommended surface preparation for use in standard tests of building seals and sealants.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This guide suggests a simple means of evaluating the extent of any failure of a structural sealant in an installed structural sealant glazing system.  
5.2 A qualified authority should specify the criteria described in Sections 8 and 9 and should interpret the results and judge their significance for the structural sealant glazing system.  
5.3 The evaluation program measures deflection of loaded lites and does not measure directly any structural sealant failure. Consequently, the qualified authority interpreting the data should also evaluate the source of any increased deflection that is measured. Increased deflection may be due to structural sealant adhesive or cohesive failure, but may also be due to a decrease in sealant modulus, a change in sealant joint dimensions, or other nonfailure mechanisms. Selective destructive sampling of areas with increased deflections can assist in this evaluation.
SCOPE
1.1 This guide covers a screening approach to detect failure (adhesive or cohesive) of a structural sealant in a structural sealant-glazed window, curtain wall, or other similar system. Presently, only a silicone-sealant that is specifically formulated, tested, and marketed as a structural glazing sealant is allowed for structural sealant glazing.  
1.2 The values stated in either acceptable metric units or in other units shall be regarded separately as the standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.3 There are no ISO standards similar or equivalent to this ASTM standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Guidelines are provided for remedying existing SSG installations. Refer to Guide C1401 for a complete discussion of proper SSG design, installation, and materials.  
4.2 Due to the unlimited range of materials that may be used in a particular building, and because each design is unique, the information contained in this guide is general in nature.  
4.3 This guide should not be the only reference consulted when designing remedies for SSG. For example, the local building code and the manufacturers' product literature for the actual materials used, if known, also should be considered. The sealant manufacturer(s) should be involved fully with the remedial design.  
4.4 This guide is intended to be a resource, but it is not a substitute for experience and judgement in designing remedies for the specialized types of construction discussed. It is intended to be used in conjunction with other resources as an aid in remedying problems with existing SSG.
SCOPE
1.1 This guide provides recommendations for remedying existing structural sealant glazing (hereinafter called SSG) installations in situ. Remedial work may be necessary when a lite of glass is replaced, for routine maintenance, or after distress is discovered. This guide focuses on large-scale remedies, not isolated repairs or maintenance.  
1.2 Committee C24 is not aware of any comparable standards published by other organizations.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers cold, liquid-applied, single or multi-component, chemically curing, elastomeric secondary edge sealants for sealed structurally glazed insulating glass units. Only the minimum acceptable test requirements for and the durability of these materials are described by this specification. A sealant that qualifies under this specification is classified into two types according to the number of components and into two uses according to application. Sealants should conform to the required values of extrudability, rheology, hardness, heat aging, weight loss, cracking, chalking, durability, tensile strength, and minimum shelf life.
SIGNIFICANCE AND USE
7.1 Not all sealants meeting this specification should be presumed to be suitable for all applications and all substrates. This specification assists in selecting sealants that meet certain minimum standards of performance.  
7.2 This specification does not evaluate the adhesion of the secondary sealant to the IG unit spacer. Adhesion of the secondary sealant to the spacer is generally considered necessary for the successful performance of the IG unit edge seal.  
7.3 When specifying a sealant using this specification, it is essential that the applicable type and use also be included in the requirements. This will ensure that the proper sealant is provided for the intended use.  
7.4 IG units qualified by this specification shall have a low moisture vapor transmission sealant for a primary seal and a structural silicone sealant for a secondary seal.  
7.5 This specification does not address appropriate sealant stiffness since the appropriate stiffness is a function of the particular insulating glass system in which the sealant is used (that is, varies with spacer, shape and set back, and sealant configuration). Test Method C1265 can assist in evaluating these aspects of the sealant in a particular IG system.
SCOPE
1.1 This specification describes the properties of cold, liquid-applied, single or multi-component, chemically curing, elastomeric sealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the “sealant” (see Fig. 1). These sealants are intended to be a structural component of sealed insulating glass (IG) units used in structural sealant glazing (hereinafter referred to as SSG). Typical designs and considerations can be found in Guide C1249. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications.
FIG. 1 Cutaway Section of IG Unit Edge Seal  
1.2 This specification does not describe all of the necessary properties of the sealant. Only those properties for which there are ASTM test methods and industry-agreed-upon minimum acceptable test requirements are described by this specification. Additional properties will be added as ASTM test methods for these properties become available.  
1.3 This specification only addresses the durability of the secondary edge sealants for structurally glazed insulating glass units. Durability of sealed insulating glass units can be found in specifications and guides that reside within ASTM Committee E06.  
1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers the properties of a cured single- or multicomponent cold-applied elastomeric joint sealant for sealing, caulking, or glazing operations on buildings, plazas, and decks for vehicular or pedestrian use, and types of construction other than highway and airfield pavements and bridges. A sealant qualifying under this specification shall be classified as to type, grade, class and use as follows: type S - a single-component sealant, type M - a multicomponent sealant, grade P - a pourable or selfleveling sealant, grade NS - a nonsag or gunnable sealant, class 100/50, class 50, class 35, class 25, class 12.5, use T, use NT, use I, use M, use G, use A, and use O. A single-component sealant shall be a uniform mixture of a consistency suitable for immediate application by hand or pressure caulking gun or by hand tool. A multicomponent chemically curing sealant shall be furnished in two or more components. A single-component and multicomponent sealant, when stored in the original unopened container at temperatures of not more than 27°C (80°F) shall be capable of meeting the requirements for at least 6 months after date of delivery. Grade P (pourable or selfleveling) sealant shall have the required flow characteristics, it shall exhibit a smooth, level surface. Grade NS or gunnable sealant shall have the required flow characteristics such that when tested in vertical displacement. Type S, grade P, and grade NS sealant shall not be less than the given extrusion rate when tested. Type M and grade P sealant, when tested shall be not less than the given extrudable rate 3 h after mixing. Use T (traffic) sealant shall have a hardness reading, after being properly cured, of not less than 25 or more than 50 when tested. Use NT (nontraffic) sealant shall have a hardness reading, after being properly cured, of not less than 15 or more than 50 when tested. The sealant shall not lose more than 7 % of its original weight or show any cracking or chalking when tested. There shall be no transfer of the sealant to the polyethylene film when tested at 72 h. The sealant shall not cause any visible stain on the top surface of a white cement mortar base when tested. The adhesion and cohesion after cyclic movement shall be tested to meet the requirements prescribed. The adhesion-in-peel test shall be performed to meet the requirements precribed. The adhesion-in-peel after ultraviolet exposure through glass shall be determined to meet the requirements prescribed. The accelerated weathering effects, and sealants exposed to continuous immersion shall be determined to meet the requirements prescribed.
SIGNIFICANCE AND USE
7.1 This specification covers several classifications of sealants as described in Section 4 for various applications. It should be recognized by the purchaser or design professional that not all sealants meeting this specification are suitable for all applications and all substrates. It is essential, therefore, that the applicable type, grade, class, and use be specified so that the proper classification of sealant is provided for the intended use. Test methods relate to special standard specimen substrates of mortar, glass, and aluminum. If tests are required using substrates in addition to or other than the standard, they should be so specified for testing.
SCOPE

1.1 This guide provides photographs that illustrate seal and sealant behavior consistent with the scope and areas of interest of Committee C24.  
1.2 When available, photographs that better illustrate these terms, or that illustrate additional terms defined by Committee C24, will be included in future editions of this standard. Photographs for consideration may be submitted to the committee using the form in Appendix X1.  
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 The intent of this guide is to provide information and guidelines for consideration by the designer or applicator of joint seals in, or adjacent to, EIFS. Refer to Specification E2568 for additional information pertaining to specifying Class PB EIFS. Refer to Guide E2511 for additional information pertaining to detailing of EIFS-Clad Wall Assemblies.  
4.2 Proper selection and use of a sealant is fundamental to its ultimate performance, service life, and durability.

1.5 There are no ISO standards similar or equivalent to this ASTM standard.

SIGNIFICANCE AND USE
5.1 The old saying “A chain is only as strong as its weakest link” is very applicable to a SSG system. In reality, a SSG system, to be successful, must establish and maintain a chain of adhesion. For example, a factory applied finish must adhere adequately to a metal framing member, a structural glazing sealant to that metal finish, that structural glazing sealant to a reflective coating on a glass lite, and lastly, that reflective coating to a glass surface. This guide will assist in the identification and development of, among others, performance criteria, test methods, and industry practices that should be implemented to obtain the required structural glazing sealant adhesion and compatibility with other system components.  
5.2 Although this guide has been arranged to permit easy access to specific areas of interest, it is highly recommended that the entire guide is read and understood before establishing the requirements for a particular SSG system.  
5.3 This guide should not be the only criteria upon which the design and installation of a SSG system is based. The information herein is provided to assist in the development of a specific program with a goal of achieving a successful SSG system installation. Information and guidelines are provided for the evaluation, design, installation, and maintenance of a SSG system and many of its various components. Considering the range of properties of structural glazing silicone sealants, as well as the many types of framing system designs, material combinations that can be used, various material finishes, and the many types and varieties of accessories, the information contained herein is general in nature.  
5.4 Generally, the design, fabrication, and installation of a SSG system requires more technical knowledge and experience then is required for a conventionally glazed window or curtain wall system. To ensure the success of a SSG system, it is important that suppliers, fabricators, and installers of materials an...
SCOPE
1.1 Structural sealant glazing, hereinafter referred to as SSG, is an application where a sealant not only can function as a barrier against the passage of air and water through a building envelope, but also primarily provides structural support and attachment of glazing or other components to a window, curtain wall, or other framing system.  
1.2 This guide provides information useful to design professionals, manufacturers, contractors, and others for the design and installation of a SSG system. This information is applicable only to this glazing method when used for a building wall that is not more than 15° from vertical; however, limited information is included concerning a sloped SSG application.  
1.3 Only a silicone chemically curing sealant specifically formulated, tested, and marketed for structural sealant glazing is acceptable for a SSG system application.  
1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. SI units in this guide are in conformance with IEEE/ASTM SI 10.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Walls, ceilings, and floors in building construction, especially those that are of lightweight construction, and that are designed to reduce or limit sound transmission, can have undesirable sound transmission characteristics if care is not taken to seal joints, voids, and penetrations that typically occur. Unsealed joints, voids, and penetrations will substantially increase the sound transmission characteristics of these types of construction. By sealing them the transmission of sound can be substantially diminished by eliminating “flanking paths.”
SCOPE
1.1 This practice provides information for the use of sealants to reduce sound transmission characteristics of interior walls, ceilings, and floors by proper application of sealants to joints, voids, and penetrations normally found in building construction, which are commonly referred to as “flanking paths.”  
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.3 This standard does not purport to address fire stopping or safing requirements for joints, voids, and penetrations through fire-rated wall, ceiling, and floor assemblies. Additional requirements may be necessary for fire-rated assemblies to meet the applicable building code provisions.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Importance of Prequalification—For required accuracy of test results and reliability of certification, it is essential that testing laboratories be prequalified. This practice establishes those qualifications.  
4.2 Contractual Relationships:  
4.2.1 Although testing laboratories may be qualified in accordance with this practice, it is important for the contracting authority to consider the relationship of the testing laboratory with other interested parties before engaging the laboratory to perform the testing. The other interested parties in the project usually consist of the manufacturer of the material to be tested, the contractor (bidder), the owner of the project (user and contracting authority), and the architect who serves as the owner's agent in preparing the contract documents.  
4.2.2 Many sealant manufacturers have their own qualified testing facilities that are used to conduct research and maintain quality control of their products. Generally, the companies that have such facilities are willing to certify as to the performance standards with which their products comply. The contracting authority should determine if there are conflicting interests in such a relationship. The contracting authority may prefer that the product testing to ascertain conformance with specific performance standards and the reporting of such testing be performed by a qualified but independent testing laboratory. The contract documents should make this requirement known so that bidders can bid accordingly.  
4.2.3 The testing of each caulking and sealant for each and every project can be costly. On a small building project, the cost of testing, if required, may be more than the cost of the sealant materials. On a large project, on the other hand, the cost of testing a sealant with accompanying certification by a qualified independent testing laboratory may be small in comparison to the sealant materials and commensurate with the assurances desired by the contracting auth...
SCOPE
1.1 This practice describes the qualifications, including minimum requirements for personnel and equipment, duties, responsibilities, and services of independent commercial materials testing laboratories engaged in the testing of caulking and sealants used in building construction.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This standard specification covers the basic requirements for cylindrical sealant backing for use with cold liquid-applied sealants. Cylindrical sealant backings are classified into three types: type C, type O, and type B, composed predominantly of closed cell material, open cell material, and bi-cellular material, respectively. Test methods for cylindrical sealant backing include water absorption, density, outgassing, compression deflection and recovery, and tensile strength. The sealant shall be clean, free of scale, foreign matter, oil, or water.
SIGNIFICANCE AND USE
5.1 This specification is designed to give some indication as to the differences in performance for various cylindrical sealant backings.  
5.2 Although this specification qualifies a cylindrical sealant backing for use, it does not address the compatibility of the backing with the sealants with which it will make contact. Sealant compatibility should be confirmed by the sealant manufacturer. Compatibility characteristics of sealants in contact with cylindrical sealant backings can be determined by Test Method C1087.
SCOPE
1.1 This specification covers the basic requirements for cylindrical sealant backing to be used with cold liquid applied sealants for use in building seals.  
1.2 Cylindrical sealant backing serves one or more of the following functions:  
1.2.1 Limits the amount and depth of sealant applied into a joint,  
1.2.2 Acts as a bond breaker to allow joint movement without undue stress to the sealant,  
1.2.3 Provides a form to assist the sealant in developing the proper shape factor, and  
1.2.4 Acts as a barrier to the flow of sealant through the joint.  
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTM committees or other organizations.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers latex sealants used for sealing joints in building construction. The following are the type and grade of sealant under this specification: Type OP, Type C, Grade -18°C, Grade 0°C, and Grade NF. The sealant shall be composed of latex formulated with appropriate fillers, pigments, and chemical additives. The physical properties of the sealant shall conform to the specified requirements according to type and grade. The following tests shall be done: extrudability after aging, artificial weathering, volume shrinkage, low-temperature flexibility, extension-recovery and adhesion, slump, staining, and tack-free time.
SIGNIFICANCE AND USE
8.1 This specification covers two types and three grades of latex sealants as described in Section 4 that are formulated for general caulking and sealing operations in building construction. It should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates. It is essential, therefore, that the type and grade be specified for proper description of a sealant. Test methods relate to special standard substrates of glass, wood and aluminum. If tests are required using substrates in addition to or other than standard, they should be so specified for testing.  
8.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
SCOPE
1.1 This specification covers one component latex sealants used for sealing joints in building construction.  
1.2 A sealant meeting the requirements of this specification shall be classified by the manufacturer to be one of the types and grades defined in Section 4.  
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound in parenthesis are provided for information purposes only.  
1.4 The following precautionary caveat pertains only to the test method portion, Section 10, of this Specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1: Currently, there is no ISO standard similar to this specification.

SIGNIFICANCE AND USE
4.1 Design professionals, for aesthetic reasons, have desired to limit the spacing and width of sealant joints on exterior walls and other locations of new buildings. Analysis of the performance factors and especially tolerances that affect a sealant joint is necessary to determine if a joint will have durability and be effective in maintaining a seal against the passage of air and water and not experience premature deterioration. If performance factors and tolerances are not understood and included in the design of a sealant joint, then the sealant may reach its durability limit and failure is a distinct possibility.  
4.2 Sealant joint failure can result in increased building energy usage due to air infiltration or exfiltration, water infiltration, and deterioration of building systems and materials. Infiltrating water can cause spalling of porous and friable building materials such as concrete, brick, and stone; corrosion of ferrous metals; and decomposition of organic materials, among other effects. Personal injury can result from a fall incurred due to a wetted interior surface as a result of a failed sealant joint. Building indoor air quality can be affected due to organic growth in concealed and damp areas. Deterioration is often difficult and very costly to repair, with the cost of repair work usually greatly exceeding the original cost of the sealant joint work.  
4.3 This guide is applicable to sealants with an established movement capacity, in particular elastomeric sealants that meet Specification C920 with a minimum movement capacity rating of ± 121/2 percent. In general, a sealant with less than ± 121/2 percent movement capacity can be used with the joint width sizing calculations; however, the width of a joint using such a sealant will generally become too large to be practically considered and installed. It is also applicable to precured sealant extrusions with an established movement capacity that meets Specification C1518.

Information in this guide is primarily applicable to single- and multi-component, cold-applied joint sealants and secondarily to precured sealant extrusions when used with properly prepared joint openings and substrate surfaces.  
1.2 Although primarily directed towards the understanding and design of sealant joints for walls for buildings and other areas, the information contained herein is also applicable to sealant joints that occur in horizontal slabs and paving systems as well as various sloped building surfaces.  
1.3 This guide does not describe the selection and properties of joint sealants (1)2, nor their use and installation, which is described by Guide C1193.  
1.4 For protective glazing systems that are designed to resist blast and other effects refer to Guide C1564 in combination with this guide.  
1.5 This guide is not applicable to the design of joints sealed with aerosol foam sealants.  
1.6 For structural sealant glazing systems refer to Guide C1401 in combination with this guide.  
1.7 The values and calculations stated in SI units are to be regarded as the standard. The values given in parentheses and inch-pound units are provided for information only. SI units in this guide are in conformance with IEEE/ASTM SI 10-1997.

ABSTRACT
This specification describes the properties of applied, flat shaped precured elastomeric silicone joint sealants that bridge joint openings and are adhered to joint substrates utilizing a liquid applied silicone adhesive sealant to seal building openings such as panel joints, metal flashing joints, or other building openings in place of conventional liquid applied sealants. Seals are applied in three different configurations, as follows: as a bridge joint, the seal is applied flat on the surface to cover a joint opening; as a beveled bridge joint, the seal is applied on the beveled edge of a substrate to bridge a joint opening.; as a U-joint, the seal is applied in a U-configuration within a joint. Seals are classified into Movement Classes on the basis of movement capability, and Tear Class on the basis of tear propagation. Seals should adhere to specified requirements as to stability, color and texture, application, adhesion and cohesion, and movement, modulus, and tear characteristics.
SCOPE
1.1 Precured elastomeric silicone joint sealants, hereinafter referred to as seal, are manufactured in flat, cured, extruded shapes and are primarily used to span joint openings in construction. This specification describes the properties of applied, flat shaped precured elastomeric silicone joint sealants, hereinafter referred to as applied seal, that bridge joint openings and are adhered to joint substrates utilizing a liquid applied silicone adhesive sealant, specified by the manufacturer, hereinafter referred to as adhesive to construction substrates, to seal building openings such as panel joints, metal flashing joints, or other building openings in place of conventional liquid applied sealants.  
1.2 Seals are applied in three different configurations:  
1.2.1 As a bridge joint, the seal is applied flat on the surface to cover a joint opening. See Fig. 1.  
1.3 This specification is for a flat extruded shape. A three-dimensional shape used at a joint cross section or termination is being considered for future inclusion in the specification.

1.5 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.

SIGNIFICANCE AND USE
4.1 This guide provides information and guidelines for consideration by the designer or applicator of a joint seal. It explains the properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures such as, substrate cleaning and priming, and installation of the components of a sealed joint. It presents guidelines for the use and application of the various materials, design of a sealant joint for a specific application, and environmental conditions and effects that are known to detrimentally affect a sealant joint. The information and guidelines are also useful for those that supply accessories to the sealant industry and for those that install sealants and accessory materials associated with sealant use.  
4.2 In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for its products and their proper use and installation. Considering the range of properties of commercially available sealants, the variety of joint designs possible, and the many conditions of use, the information contained herein is general in nature.  
4.3 It should be realized that a sealant and sealant joint are expected to have a design life during which they remain functional. However, a sealant and sealant joint will also have a service life. The intent is for service life to meet or exceed design life. There are many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacent materials, installation techniques or deficiencies, sealant joint design (or lack thereof), proper maintenance (or lack thereof), and environmental exposure, among others. The designer of a joint seal should take the above into consideration when designing and specifying sealants for certain applications.  
4.4 The design life of a sealant or sealant joint should be considered in conjunction with the design life of the structure for which it is us...

SIGNIFICANCE AND USE
4.1 Guidelines are provided for the use of silicone sealants in protective glazing. Protective glazing incorporates various forms of glazing that are not covered in Guides C1401 and C1193. The requirements for a sealant in protective glazing are similar to the requirements for structural sealant glazing but for certain applications such as missile impact and bomb blast glazing, sealant requirements may be greater. Modes of failure for bomb blast glazing can be different than the modes of failure for missile impact glazing.  
4.2 Many types of protective glazing systems are relatively new and the test methods and standards for protective glazing are continually evolving. Because the demands on a sealant in protective glazing systems are changing, guidelines are necessarily general in many instances.  
4.3 As a component of a glazing system, the sealant can be a factor in whether a glazing system meets the requirements of a specific test method but other factors such as the frame and glass type may be of greater influence.  
4.4 The designer of a protective glazing system should consult with the various manufacturers of the component materials. The experience and judgment of the glazing system designer working with the sealant manufacturer and other component manufacturers can ultimately determine whether a specific glazing system will successfully meet a specific test requirement.
SCOPE
1.1 This guide covers the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural disasters such as hurricanes, earthquakes, windstorms and forms of forced entry such as blasts, burglary, and ballistic attack.  
1.2 While other glazing accessories and components are used in protective glazing, this document specifically describes the use of silicone sealants for protective glazing systems.  
1.3 This guide provides information useful to design professionals, architects, manufacturers, installers, and others for the design and installation of silicone sealants for protective glazing systems.  
1.4 A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for impact glazing must successfully integrate the frame and its anchorage, glass, or other glazing materials, protective film or interlayer and silicone sealant into a high performance system. Compliance with code or other requirements can be determined through physical testing of the glazing system or through computer simulation.  
1.5 Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and bomb blast test requirements incorporate the use of silicone sealants specifically formulated, tested, and marketed for this application. Sealants that are commonly used today comply with Specifications C920 and C1184.  
1.6 This guide does not discuss sealants intended to protect against radioactivity or provide biological containment.  
1.7 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

SIGNIFICANCE AND USE
5.1 The intent of this guide is to provide the reader with information concerning possible reasons for paint failures where the paint is used over a latex sealant.

SIGNIFICANCE AND USE
7.1 This specification covers several classifications of sealants as described in Section 4 for various applications. It should be recognized by the purchaser or design professional that not all sealants meeting this specification are suitable for all applications and all substrates. It is essential, therefore, that the applicable type, grade, class, and use be specified so that the proper classification of sealant is provided for the intended use. Test methods relate to special standard specimen substrates of mortar, glass, and aluminum. If tests are required using substrates in addition to or other than the standard, they should be so specified for testing.

ABSTRACT
This specification covers cold, liquid-applied, single or multi-component, chemically curing, elastomeric secondary edge sealants for sealed structurally glazed insulating glass units. Only the minimum acceptable test requirements for and the durability of these materials are described by this specification. A sealant that qualifies under this specification is classified into two types according to the number of components and into two uses according to application. Sealants should conform to the required values of extrudability, rheology, hardness, heat aging, weight loss, cracking, chalking, durability, tensile strength, and minimum shelf life.
SIGNIFICANCE AND USE
7.1 Not all sealants meeting this specification should be presumed to be suitable for all applications and all substrates. This specification assists in selecting sealants that meet certain minimum standards of performance.  
7.2 This specification does not evaluate the adhesion of the secondary sealant to the IG unit spacer. Adhesion of the secondary sealant to the spacer is generally considered necessary for the successful performance of the IG unit edge seal.  
7.3 When specifying a sealant using this specification, it is essential that the applicable type and use also be included in the requirements. This will ensure that the proper sealant is provided for the intended use.  
7.4 IG units qualified by this specification shall have a low moisture vapor transmission sealant for a primary seal and a structural silicone sealant for a secondary seal.  
7.5 This specification does not address appropriate sealant stiffness since the appropriate stiffness is a function of the particular insulating glass system in which the sealant is used (that is, varies with spacer, shape and set back, and sealant configuration). Test Method C1265 can assist in evaluating these aspects of the sealant in a particular IG system.
SCOPE
1.1 This specification describes the properties of cold, liquid-applied, single or multi-component, chemically curing, elastomeric sealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the “sealant” (see Fig. 1). These sealants are intended to be a structural component of sealed insulating glass (IG) units used in structural sealant glazing (hereinafter referred to as SSG). Typical designs and considerations can be found in Guide C1249. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications.  
1.2 This specification does not describe all of the necessary properties of the sealant. Only those properties for which there are ASTM test methods and industry-agreed-upon minimum acceptable test requirements are described by this specification. Additional properties will be added as ASTM test methods for these properties become available.  
1.3 This specification only addresses the durability of the secondary edge sealants for structurally glazed insulating glass units. Durability of sealed insulating glass units can be found in specifications and guides that reside within ASTM Committee E06.  
1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.

ABSTRACT
This specification describes the properties of one-component solvent release sealants for use in building construction. These sealants are generally formulated to withstand a specified maximum joint movement in extension and compression of the nominal joint width. The sealants shall be tested, and is expected to conform to the following physical properties: extrudability after aging, shore A hardness, indentation hardness, bubbling, adhesive and cohesive loss after cyclic movement, slump, stain index, tack-free time, and accelerated weathering (edge cracking, center cracking, adhesion loss, and color change).
SIGNIFICANCE AND USE
6.1 This specification describes solvent release sealants for general caulking and sealing operations in building construction. However, it should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates and that there is no implication that the sealants are equivalent in all physical properties.  
6.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
SCOPE
1.1 This specification describes the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5 % in extension and 7.5 % in compression of the nominal joint width.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization.

ABSTRACT
This specification describes the properties of cold liquid applied, single-component or multicomponent, chemically curing elastomeric structural silicone sealants herein referred to as the sealant. These sealants are intended to structurally adhere components of structural sealant glazing systems. Sealants shall be classified as to types and uses: Type S; Type M; Use G; and Use O. The physical, mechanical, and performance properties of the sealant shall conform to the requirements described. The following test methods shall be performed: rheological properties; extrudability; hardness; heat aging; tack-free time; tensile adhesion; and shelf life.
SCOPE
1.1 This specification describes the properties of cold liquid applied, single-component or multicomponent, chemically curing elastomeric structural silicone sealants herein referred to as the sealant. These sealants are intended to structurally adhere components of structural sealant glazing systems.  
1.2 Only those properties for which there are industry-agreed-upon minimum acceptable requirements, as determined by available ASTM test methods, are described in this specification. Additional properties may be added as ASTM test methods for those properties become available.  
1.3 The values stated in metric (SI) units are to be regarded as the standard. The values in parentheses are for information only.  
1.4 Committee C24, with jurisdiction over this specification, is aware of two comparable standards by other organizations: ETAG No. 002 and the Chinese national standard GB16776.

SIGNIFICANCE AND USE
5.1 The old saying “A chain is only as strong as its weakest link” is very applicable to a SSG system. In reality, a SSG system, to be successful, must establish and maintain a chain of adhesion. For example, a factory applied finish must adhere adequately to a metal framing member, a structural glazing sealant to that metal finish, that structural glazing sealant to a reflective coating on a glass lite, and lastly, that reflective coating to a glass surface. This guide will assist in the identification and development of, among others, performance criteria, test methods, and industry practices that should be implemented to obtain the required structural glazing sealant adhesion and compatibility with other system components.  
5.2 Although this guide has been arranged to permit easy access to specific areas of interest, it is highly recommended that the entire guide is read and understood before establishing the requirements for a particular SSG system.  
5.3 This guide should not be the only criteria upon which the design and installation of a SSG system is based. The information herein is provided to assist in the development of a specific program with a goal of achieving a successful SSG system installation. Information and guidelines are provided for the evaluation, design, installation, and maintenance of a SSG system and many of its various components. Considering the range of properties of structural glazing silicone sealants, as well as the many types of framing system designs, material combinations that can be used, various material finishes, and the many types and varieties of accessories, the information contained herein is general in nature.  
5.4 Generally, the design, fabrication, and installation of a SSG system requires more technical knowledge and experience then is required for a conventionally glazed window or curtain wall system. To ensure the success of a SSG system, it is important that suppliers, fabricators, and installers of materials an...
SCOPE
1.1 Structural sealant glazing, hereinafter referred to as SSG, is an application where a sealant not only can function as a barrier against the passage of air and water through a building envelope, but also primarily provides structural support and attachment of glazing or other components to a window, curtain wall, or other framing system.  
1.2 This guide provides information useful to design professionals, manufacturers, contractors, and others for the design and installation of a SSG system. This information is applicable only to this glazing method when used for a building wall that is not more than 15° from vertical; however, limited information is included concerning a sloped SSG application.  
1.3 Only a silicone chemically curing sealant specifically formulated, tested, and marketed for structural sealant glazing is acceptable for a SSG system application.  
1.4 The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.  
1.5 The calculations and values stated in SI units are to be regarded as the standard. Values in parenthesis and inch-pound units are for information only. SI units in this guide are in conformance with IEEE/ASTM SI 10.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification describes preformed tape sealants for use in glazing applications. These materials are generally used to serve as components of glazing systems. They are intended to serve as a water and air barrier. The preformed tape sealant shall be composed of appropriate raw materials conformed to the requirements specified. The preformed tape sealant shall be of uniform dimensions and consistency. When properly applied, this material shall form a seal to prevent air and water from entering the system. Different test methods shall be performed in order to determine the following properties: low temperature flexibility, weight loss, vehicle migration, backing removal, yield strength, compression or recovery, water absorption, and flow.
SIGNIFICANCE AND USE
6.1 This specification describes only preformed tape sealants for glazing applications. Their use is specific under glazing systems to serve as a water and air barrier. The test methods chosen are to determine their efficiency in this use. This specification does not describe all required properties of the preformed tape sealants. It should be recognized by the purchaser and design professional that not all preformed tape sealants meeting this specification are suitable for all applications. In some instances, additional requirements will be agreed to by the supplier and user.
