ASTM C1775-13 PDF

1.1 This specification addresses the minimum performance for flexible laminate protective jacket and a pressure sensitive adhesive tape for use over thermal insulation on pipes, duct, and equipment operating at both above and below ambient temperatures and installed outdoors, above ground. It does not include the following: protective metal jacket, homogenous plastic film jacket materials, modified asphalt jacket materials, and butyl rubber membranes.

1.2 This type of material consists of multiple layers of plastic film and foil laminated to one another with layer(s) of reinforcement as an option.

1.3 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. The water vapor transmission tests are for the jacket and tape materials only and not for overlaps or taped joints. All materials are weather resistant and of sufficient strength to provide protection for mechanical insulation.

1.4 Materials covered under this specification will have a high, medium, or low surface emittance and are available in more than one color.

1.5 This specification includes jacket materials both with and without factory applied, pressure sensitive adhesives. The tape materials covered by this specification always have a factory applied, pressure sensitive adhesive.

1.6 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.

1.7 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.
