5.1 Residential duct systems are often field designed and assembled. There are many joints, often of dissimilar materials that require both mechanical connection and air sealing. Without this sealing, duct systems would be extremely leaky and hence inefficient. While some duct sealants are rated on their properties at the time of manufacture or during storage, none of these ratings adequately addresses the in-service lifetime. This test method has been developed to address this durability issue.5.2 This standard applies to products which list duct sealing as one of their uses. This includes duct tape (cloth, metal foil, or plastic backed), mastics, and sprayed/aerosol sealants. It does not apply to caulks or plaster patches that are not intended to be permanent duct sealing methods.5.3 The standard duct leak site is a collar to plenum connection for round duct that is 10 cm to 20 cm [4 in. to 8 in.] in diameter. This perpendicular connection was chosen because almost all residential duct systems have this type of connection and in field observations of duct systems, it is often this type of connection that has sealant failure.1.1 This test method describes an accelerated aging test for evaluating the durability of duct sealants by exposure to temperatures and static pressures characteristic of residential duct systems.1.2 This test method is intended to produce a relative measure of the durability of duct sealants. This standard does not measure durability under specific conditions of weather and building operation that might be experienced by an individual building and duct system. Instead it evaluates the sealant method under fixed conditions that do not include the manifold effects of installation practice.1.3 This test method only addresses sealants not mechanical strength of the connections.1.4 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.1.5 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. For specific hazard statements see Section 7.1.6 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.

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.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.

4.1 Staining of a building is an aesthetically undesirable occurrence. This test method evaluates the likelihood of a sealant causing an early stain on a porous substrate, when the stain is caused by gross exudation from the sealant. This test method does not predict staining caused by other factors.4.2 See also Test Method C510.1.1 This test method covers a laboratory procedure for determining whether a sample of sealant will cause staining of the substrate when in the contact with masonry, concrete, or stone (marble, limestone, sandstone, granite, etc.).1.2 The values stated in SI (metric) units are to be regarded as the standard. The values given in parentheses are provided for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 The intent of this test method is to determine the time dependence of modulus in building joint sealants using two loading-unloading cycles to identify and mitigate any Mullins effect, and followed by a stress relaxation procedure to determine the time dependent modulus.5.2 This test method has found applications in screening the performance of building joint sealants since the modulus is one indicator of the ability of elastomeric building sealant to withstand environmental induced movements.1.1 This test method covers a procedure for measuring the time dependence of modulus in elastomeric joint sealants in a test specimen configuration described in Test Method C719. These sealant materials are typified by highly filled rubber materials. Any Mullins effect is first assessed and mitigated in two loading-unloading cycles. Time dependence of modulus in materials is then determined using a stress relaxation procedure.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.

5.1 The tack-free time is a measure of the surface cure time and may generally be correlated to a variety of useful parameters such as the time interval before the sealant (1) resists damage by touch or light surface contact, (2) resists job-site or airborne dirt pick-up, (3) resists impinging rainfall.5.2 The tack-free time is sometimes used as an on-the-job quality assurance test. A quality product that is consistent and reproducible will generally fall within a maximum and minimum tack-free time.5.3 This test for tack-free time can be used at any temperature and humidity. It is important that if a sealant will be used in a climate quite different than the standard conditions called out in this test method, then those conditions be used to test the sealant.1.1 This test method covers a procedure for the determination of the tack-free time property of single- and multi-component elastomeric sealants commonly used for sealing, caulking, and glazing in buildings and related construction.1.2 This test method is applicable to self-leveling and non-sag grades of sealant. Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.NOTE 1: See Specification C920 for type and grade definitions.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 all of the safety concerns, if any, associated with its use.
