Standard Specification for Secondary Edge Sealants for Structurally Glazed Insulating Glass Units

Standard Specification for Secondary Edge Sealants for Structurally Glazed Insulating Glass Units

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.

Standard Guide for Evaluating Temperature Effects to Aerosol Foam Sealant During and After Dispensing

SIGNIFICANCE AND USE
5.1 This guide is not intended to measure the precise temperature range for dispensing and curing product under all the possible substrate and environmental factors but to provide a basis for benchmarking a foam sealant product under specific laboratory conditions.  
5.2 The product user is encouraged to evaluate each application and determine suitability for actual use.
SCOPE
1.1 This guide covers the general effects of temperature from the aerosol foam sealant (either polyurethane or latex types) under the use temperatures.  
1.2 The guide is intended to estimate the observed product dispensing characteristics and foam quality of aerosol foam dispensed or cured, or both, at specific temperatures and standard conditions.  
1.3 Such foam sealants are primarily intended to reduce air movement in and out of building enclosures.  
1.4 Currently two main foam sealant types are applicable to this standard: single component polyurethane and latex.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 There are no other known test methods specific for measuring the product temperature range for aerosol foam sealant.  
1.7 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.  
1.8 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.

ASTM C1257-15(2023)(Test Method)
Standard Test Method for Accelerated Weathering of Solvent-Release-Type Sealants

SIGNIFICANCE AND USE
5.1 It is difficult to establish a precise correlation between laboratory accelerated and natural weathering because of  (1) geographical climatic variations, local weather variation from normal, and local pollutants and (2) the fact that the acceleration factor is material dependent, varying with the type of material as well as its formulation. This test method is used to determine the resistance of a sealant to laboratory accelerated weathering and, if a control material with known outdoor weathering performance is used, the relative weathering performance of the sealant against that of the control material.  
5.2 This test method is conducted using aluminum channels. Other substrate materials may show different results.
SCOPE
1.1 This test method includes two laboratory accelerated exposure procedures for predicting the effects of ultraviolet or ultraviolet/visible radiation, heat, and moisture on color, chalking, cracking, and adhesion of solvent-release sealants.  
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 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.

ASTM C1401-23(Guide)
Standard Guide for Structural Sealant Glazing

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.

Standard Test Method for Slump of Sealants

SIGNIFICANCE AND USE
4.1 Excessive sealant slump or sag in a vertical joint may cause improper bead shape or inadequate sealant thickness in the completed joint. Slump measurements, as described in this test method, serve to evaluate only this application characteristic; they do not predict the performance capability of the sealant after installation.
SCOPE
1.1 This test method covers a laboratory procedure for the determination of the degree of slump of a sealant when used in a vertical joint in a structure.  
1.2 The values stated in either inch-pound or SI (metric) units are to be separately regarded as the standard. Within the text, the inch-pound units are shown in parentheses.  
1.3 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.
Note 1: A related ISO standard is ISO 7390. The user should compare to determine how it differs from this test method.  
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.

ASTM C1021-08(2023)(Practice)
Standard Practice for Laboratories Engaged in Testing of Building Sealants

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.

ASTM C782-13(2023)(Test Method)
Standard Test Method for Softness of Preformed Tape Sealants

SIGNIFICANCE AND USE
5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in a variety of sealing applications. This procedure measures the softness of a preformed tape sealant and gives an indication of the preformed tape sealant's ease of compression during installation. The resistance to penetration may also give an indication of the toughness of the preformed tape sealant.
SCOPE
1.1 This test method describes a laboratory procedure for determining the softness of preformed tape sealants.  
Note 1: Cone penetration methods applicable to greases and to petrolatum are described in Test Methods D217 and D937. Test Method D2451 also uses a penetration technique for determining the degree of set in sash glazing compounds.  
1.2 The values stated in SI units are to be regarded as standard. Temperature values are also provided (in parentheses) in degrees Fahrenheit.  
1.3 The subcommittee with jurisdiction is not aware of any similar ISO 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.

ASTM C793-23(Test Method)
Standard Test Method for Effects of Laboratory Accelerated Weathering on Elastomeric Joint Sealants

SIGNIFICANCE AND USE
5.1 It is known that solar radiation contributes to the degradation of sealants in exterior building joints. The use of a laboratory accelerated weathering machine with actinic radiation, moisture and heat appears to be a feasible means to give indications of early degradation by the appearance of sealant cracking. However, simulated weather factors in combination with extension may produce more severe degradation than weather factors only. Therefore, the effect of the weathering test is made more sensitive by the addition of the bending of the specimen at cold temperature.
SCOPE
1.1 This test method covers a laboratory procedure for determining the effects of accelerated weathering on cured-in-place elastomeric joint sealants (single- and multicomponent) for use in building construction.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
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.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.

Standard Specification for Cylindrical Sealant Backing for Use with Cold Liquid-Applied Sealants

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.

Standard Test Method for Determining Compatibility of Liquid-Applied Sealants with Accessories Used in Structural Glazing Systems

SIGNIFICANCE AND USE
5.1 In structural sealant glazing systems, the sealant functions as the structural adhesive and may also function as the primary weather seal. As the structural adhesive, the integrity of the adhesive bond is critical.  
5.2 Changes in color and adhesion after exposure are two of the criteria that can be used to determine the compatibility of the system. Experience has shown that accessories that cause loss of adhesion or discoloration in this test method may also cause these occurrences in actual use.
SCOPE
1.1 This test method covers a laboratory screening procedure for determining the compatibility of liquid-applied structural sealant glazing sealants when in contact with accessories such as dry glazing gaskets, spacers, shims, and setting blocks after exposure to heat and ultraviolet light.  
1.2 This test method includes the observation of three parameters as follows:  
1.2.1 Changes in the color of the sealant,  
1.2.2 Changes in the adhesion of the sealant to glass, and  
1.2.3 Changes in the adhesion of the sealant to the accessory being tested.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.
Note 1: At this time, no comparable ISO standard exists.  
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.
