1.Scope 1.1.This specification addresses the minimum performance for flexible laminate protective jacket and tape, with an integral adhesive, for use over thermal insulation on pipes, duct, and equipment operating at both above and below ambient temperatures and installed above ground. It does not include protective metal jacket nor does it include homogeneous plastic film jacket materials. For aluminum jacket, see C1729. 1.2.This type of material consists of multiple layers of film and foil laminated to one another with layer(s) of reinforcement as an option. Jacket materials containing paper and designed for indoor use are addressed in specification C1136 and are not addressed in this specification. 1.3.This specification includes jacket and tape materials designed for use outdoors but that does not preclude the use indoors so long as the material meets code requirements. 1.4.While all jacket and tape materials covered by this specification have low water vapor permeance values, they are not necessarily always used as vapor retarders. All are weather resistant and of sufficient strength to protect any mechanical insulation. 1.5.Materials covered under this specification may have a high, medium, or low surface emittance and are available in more than one color. 1.6.This specification includes jacket materials both with and without factory applied, pressure sensitive adhesives. However, the tape materials covered by this specification always have a factory applied, pressure sensitive adhesive. Fabricator or field applied adhesives are not included. 1.7.This specification does not include protective jacket made with single or multiple layers of sheet rubber or rubberized bitumen with or without a film or foil facing. 1.8.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. 1.9.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.
Laminate protective jacket materials, for use over thermal insulation, are commercially available and are being used extensively on insulated ducts and to a lesser degree on insulated pipe and equipment. A standard specification for this type of jacket material is long overdue.
