Standard Specification for Flexible, Low Permeance Vapor Retarders for Thermal Insulation
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers vapor retarders for thermal insulation, specifically, flexible materials with permeance of 0.10 perm or lower and surface burning characteristics of 25 flame spread/50 smoke or lower. These materials are intended for use at temperatures of -20 to 150°F (-29 to 66°C). It does not cover mastics or barrier coatings applied in liquid form, nor materials intended for use as weather barriers.
1.2 This specification provides physical requirements for vapor retarders. Practice C755 should provide assistance in solving problems related to moisture vapor transmission through thermal insulation materials.
1.3 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.
1.4 The following precautionary caveat pertains to the test methods portion only, 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.
