ASTM C921-02

Standard Specification for Jackets for Thermal Insulation

SCOPE
1.1 This specification covers jackets applied over thermal insulation on piping and equipment, including materials applied solely for physical protection, and materials applied as vapor retarders.
1.2 This specification provides material and/or physical requirements for jackets. Guidance in selecting the proper jacket for a given application can be found in Guide C 1423.
1.3 This specification does not cover field applied mastics or barrier coatings and their attendant reinforcements, nor does it cover jackets for buried insulation systems.
1.4 The values stated in inch-pound units are to be regarded as standard. SI units are given in parenthesis.
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.
