Standard Specification for Preformed Open–Cell Sponge Rubber Pail and Drum Gaskets

Standard Specification for Preformed Open–Cell Sponge Rubber Pail and Drum Gaskets

ABSTRACT
This specification covers preformed open-cell sponge rubber gaskets, for use in new or reconditioned pails or drums, of the following classes: Class A and Class B, each divided into Grade 1, Grade 2, and Grade 3. Cellular sponge rubber gaskets shall be made by incorporating a blowing agent into the compound, such as sodium bicarbonate, that gives off a gas which expands the mass during the vulcanization process, and shall be manufactured from natural rubber, synthetic rubber, or rubber-like materials, together with added compounding ingredients. Unless otherwise specified, gasket sponge rubber shall have a natural skin on both the top and bottom surfaces. Cellular rubber shall conform to the prescribed requirements as to physical properties such as (1) compression at deflection, (2) change in volume upon oil immersion, (3) change in compression value after heat aging, (4) compression set, and (5) color (tan or black). The following test methods shall be used: (1) compression deflection test, (2) oil immersion test, (3) heat oven aging test, and (4) compression set test under constant deflection. The formula for calculating the compression set is given. The requirements for sampling, test specimens and slabs, and measurements of test specimen such as width and thickness are detailed as well. The location from which standard test specimens are to be cut when testing standard test slabs or commercial flat sheets and the four-cavity frame for standard test slabs of cellular rubbers are illustrated.

Standard Test Methods for and Suggested Limits for Determining Compatibility of Elastomer Seals for Industrial Hydraulic Fluid Applications

SIGNIFICANCE AND USE
4.1 When more than one elastomer seal material is tested, the test methods yield comparative data on which to base judgements as to expected service quality. Suggested in-service property change limits are provided. Property changes beyond these limits will indicate limited service life of the elastomer seal.  
4.2 These test methods attempt to simulate service conditions through controlled aging and evaluation of property changes but may not give any direct correlations with actual part performance since actual service conditions vary widely. These test methods yield comparative data and indications of property changes of the elastomeric seal material under ideal service conditions. These test methods can be used for quality control purposes, for engineering assessments, for service evaluation, and for manufacturing control. The information from these test methods can be used to anticipate expected service quality.
SCOPE
1.1 These test methods cover the procedure for measuring physical properties of elastomer seals in the form of O-rings after exposure to industrial hydraulic fluids and thermal aging. The measured properties are then compared to the physical properties of elastomer seals that have not been exposed to the industrial hydraulic fluids and thermal aging. The changes in these properties form a basis for assessing compatibility when these changes are compared against the suggested limits in Table 1.  
1.2 While these test methods involve the use of O-rings, they can also be used to evaluate the compatibility of the elastomeric compounds of specialty seals with industrial hydraulic fluids and their resistance to thermal aging. The compounds can be molded into O-rings for evaluation purposes.  
1.3 These test methods provide procedures for exposing O-ring test specimens to industrial hydraulic fluids under definite conditions of temperature and time. The resulting deterioration of the O-ring material is determined by comparing the changes in work function, hardness, physical properties, compression set, and seal volume after immersion in the test fluid to the pre-immersion values.  
1.4 The values stated in SI units are to be regarded as the standard.  
1.4.1 Exception—The values given in parentheses are for information only.  
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.

Standard Test Method for Adhesion and Cohesion of One-Part Elastomeric Solvent Release Sealants

SIGNIFICANCE AND USE
4.1 The failure of a building sealant in a joint that experiences movement is manifested by cohesive failure in the sealant or adhesive failure between the sealant and substrate, or both. This test method evaluates the performance of one-part elastomeric solvent release sealants in joints subjected to movement and temperature aging.
SCOPE
1.1 This test method is a laboratory procedure that determines the adhesion and cohesion performance of one-part elastomeric, solvent release sealants at high and low temperatures by the extension and compression of test specimens.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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. For a specific precautionary statement, see Note 2.

Standard Specification for Dense Elastomeric Silicone Rubber Gaskets and Accessories

ABSTRACT
This standard specification describes products composed of dense elastomeric silicone rubber gaskets and accessories for use in sealing and glazing applications in building constructions. The products are classified according to type, hardness, class, and surface. Types include tear resistant and compression set resistant products. Surface of the product shall be smooth, clean, free from foreign matter, and shall not allow adhesion of sealants. Silicone rubber shall be manufactured from virgin polymer and shall be free from visible internal porosity, surface defects, and dimensional irregularities. The compound color shall be black unless specified otherwise. Test methods for the product shall include low temperature flexibility, hardness, compression, tensile strength, ultimate elongation, heat aging, ozone resistance, tear strength, flame propagation, specific gravity, staining, and color tests.
SIGNIFICANCE AND USE
8.1 This specification describes types (based on resistance to tearing and compression set), grades (based on durometer hardness), class (based on flame propagation requirements), and surfaces (based on surface characteristics) of products as listed in Section 4 for various applications. It is essential, therefore, that the applicable type, grade, class, and surface be specified, as well as other options stated, so that the proper product is provided for the intended use.
SCOPE
1.1 This specification describes products composed of dense elastomeric silicone rubber that are fabricated into gaskets and accessories (such as setting blocks, spacers, and shims) for use in sealing and glazing applications in building construction. These products are used to seal or serve as components of compression sealing systems between mechanically restrained surfaces in building construction and also as components in structural silicone sealant glazing systems.  
1.2 The following precautionary statement 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.  
1.3 Test Method C1166, as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment that takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.  
1.4 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.  
1.5 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
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 Practice for Periodically Measuring and Monitoring Sealant Dimensions to Stability Following a Period of Compression or Tension

SIGNIFICANCE AND USE
5.1 Many sealants have been observed to dimensionally change following a period of compression or tension, such as occurs during exposure in accordance with Practice C1589. It has been shown that for some sealants, increasing exposure to weathering increases the time required for dimensional stability and decreases the magnitude of dimensional change. Dimensional stability and knowledge of the stable sealant dimensions are critical to the accurate measurement of the sealant’s modulus by a test such as Test Method C1735.  
5.2 This practice will find application in improving the accuracy of the modulus determined by a standard such as Test Method C1735 by using the accurate dimensions determined by this practice after stability is attained.
SCOPE
1.1 This practice covers a procedure for measuring and monitoring the physical dimensions of an elastomeric joint sealant in a test specimen configuration described in Test Method C719 following a period of compression or tension. These sealant materials are typically highly filled elastic materials. The dimensional change of these sealant materials is determined by measuring the dimensions at specific intervals over a period of time.  
1.2 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.  
1.3 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.

Standard Specification for Elastomeric Cellular Preformed Gasket and Sealing Material

ABSTRACT
This specification covers elastomeric cellular preformed gasket and sealing materials. Elastomeric cellular materials shall be manufactured from natural rubber, synthetic rubber, rubber-like materials, or mixture of these, with added compounding ingredients. The material shall conform to the required physical properties such as: compression-deflection, compression set, heat aging, dimensional stability, ozone resistance, low-temperature brittleness, water absorption, flame propagation, and nonstaining. The two classifications of material according to ozone resistance are Type I and Type II. Test for each physical properties shall be made.
SIGNIFICANCE AND USE
9.1 Flame Propagation:  
9.1.1 This specification has two options:
9.1.1.1 Option I—Flame propagation test is required.
9.1.1.2 Option II—Flame propagation test is not required.  
9.1.2 In case no option is specified, Option I will apply.  
9.2 This specification has two classifications as related to ozone resistance. These are Type I and Type II, with the latter having the greater resistance to ozone. The type should be specified when making reference to this specification but in the event that the type is not specified, Type II shall apply.
Note 2: Type II is included in this specification for use where greater ozone resistance is required.
SCOPE
1.1 This specification applies to those elastomeric cellular materials of a firm grade that are manufactured in preformed shapes for use as gaskets and for use as sealing materials, in the form of compression seals or gaskets, or both, for glazing other building joint applications.  
Note 1: For softer cellular elastomeric materials used in secondary sealing applications, refer to Specification D1056.  
1.2 Test Method C1166, as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions.

Standard Specification for Preformed Open–Cell Sponge Rubber Pail and Drum Gaskets

ABSTRACT
This specification covers preformed open-cell sponge rubber gaskets, for use in new or reconditioned pails or drums, of the following classes: Class A and Class B, each divided into Grade 1, Grade 2, and Grade 3. Cellular sponge rubber gaskets shall be made by incorporating a blowing agent into the compound, such as sodium bicarbonate, that gives off a gas which expands the mass during the vulcanization process, and shall be manufactured from natural rubber, synthetic rubber, or rubber-like materials, together with added compounding ingredients. Unless otherwise specified, gasket sponge rubber shall have a natural skin on both the top and bottom surfaces. Cellular rubber shall conform to the prescribed requirements as to physical properties such as (1) compression at deflection, (2) change in volume upon oil immersion, (3) change in compression value after heat aging, (4) compression set, and (5) color (tan or black). The following test methods shall be used: (1) compression deflection test, (2) oil immersion test, (3) heat oven aging test, and (4) compression set test under constant deflection. The formula for calculating the compression set is given. The requirements for sampling, test specimens and slabs, and measurements of test specimen such as width and thickness are detailed as well. The location from which standard test specimens are to be cut when testing standard test slabs or commercial flat sheets and the four-cavity frame for standard test slabs of cellular rubbers are illustrated.
SCOPE
1.1 This specification covers preformed open–cell sponge rubber gaskets of the following classes for use in new or reconditioned pails or drums.  
1.1.1 Class A—Non–Oil Resistant.  
1.1.2 Class B—Oil Resistant.  
1.2 The values stated in SI units are to be regarded as the standard.  
1.3 The following safety hazards caveat pertains only to Section 10, General Test Methods. 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: ISO Equivalency Statement—This proposed specification was found to be not equivalent.  
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.

Standard Test Method for Extrusion Rate of Elastomeric Sealants

SIGNIFICANCE AND USE
4.1 Sealants are supplied with various rheological properties ranging from pourable liquids to nonsagging pastes. Single-component sealants are supplied ready for use upon opening the container. Multicomponent sealants are supplied as a base component(s) and a curing agent separately packaged. After mixing the two or more parts, the sealant is ready for application. This test method is intended to provide a means to measure the extrusion rate spanning the range of rheological properties.  
4.2 This test method also covers the option of measuring the freeze-thaw and heat stability of such sealants.  
4.3 This test method provides for an option of either a metal or plastic nozzle. It is intended that the metal nozzle be used when greater precision is required, such as in ASTM specifications. The plastic nozzle may be used for general screening of sealant properties or for developmental purposes when a large number of test specimens are being tested.  
4.4 This test method measures the volume of sealant extruded over a given period of time at a given pressure (kPa or psi).
SCOPE
1.1 This test method covers two laboratory procedures for determining the extrusion rate of elastomeric sealants for use in building construction.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
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.  
1.4 There is no known ISO equivalent to this test method.  
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.
