Phạm vi áp dụng / Scope of standard

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 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.

1.5 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 7.
