1、Designation: C1775 13Standard Specification forLaminate Protective Jacket and Tape for Use over ThermalInsulation for Outdoor Applications1This standard is issued under the fixed designation C1775; the number immediately following the designation indicates the year oforiginal adoption or, in the cas
2、e of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification addresses the minimum performancefor flexible laminate protective jacket
3、 and a pressure sensitiveadhesive tape for use over thermal insulation on pipes, duct,and equipment operating at both above and below ambienttemperatures and installed outdoors, above ground. It does notinclude the following: protective metal jacket, homogenousplastic film jacket materials, modified
4、 asphalt jacket materials,and butyl rubber membranes.1.2 This type of material consists of multiple layers ofplastic film and foil laminated to one another with layer(s) ofreinforcement as an option.1.3 While all jacket and tape materials covered by thisspecification have low water vapor permeance v
5、alues, they arenot necessarily always used as vapor retarders. The water vaportransmission tests are for the jacket and tape materials only andnot for overlaps or taped joints. All materials are weatherresistant and of sufficient strength to provide protection formechanical insulation.1.4 Materials
6、covered under this specification will have ahigh, medium, or low surface emittance and are available inmore than one color.1.5 This specification includes jacket materials both withand without factory applied, pressure sensitive adhesives. Thetape materials covered by this specification always have
7、afactory applied, pressure sensitive adhesive.1.6 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.7 This standard does not purport to a
8、ddress all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
