Abstract
This practice establishes the standard procedures for determining the material and physical properties for jacketing materials applied over thermal insulation on piping and equipment, including materials applied solely for physical protection, and materials applied as vapor retarders. This practice does not cover field applied mastics or barrier coatings and their attendant reinforcements, nor does it cover jackets for buried insulation systems. Jackets covered here are grouped into two types, each of which are subdivided further into grades and classes. Properties to which the jackets should conform to are permeance, tensile strength, puncture resistance, surface burning characteristics, flame resistance permeance, dimensional stability, fungi resistance, elevated temperature and humidity resistance, and thermal integrity.
Scope
1.1 This practice 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 practice provides material and physical requirements, or both, for jackets. Guidance in selecting the proper jacket for a given application can be found in Guide C1423.
1.3 This practice 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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
