ASTM C1775-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1775 − 14 C1775 − 22
Standard Specification for
Laminate Protective Jacket and Tape for Use over Thermal
Insulation for Outdoor Applications
This standard is issued under the fixed designation C1775; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
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 shall consist of multiple layers of polymer film and aluminum foil laminated to one another with layer(s)
of reinforcement as an option.
1.3 Jacket and tape materials covered by this specification shall have low water vapor permeance values; however, they are not
necessarily always used as vapor retarders. The water vapor transmission tests address the jacket and tape materials only and do
not address overlaps or taped joints. All materials shall be weather resistant and intended to have sufficient strength to provide
protection for mechanical insulation.
1.4 Materials covered under this specification shall have a high, medium, or low surface emittance.
1.5 The top layer shall be on of the following: aluminum foil, a polymer film, or a polymer coating.
1.6 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.
1.7 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.
1.8 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.9 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
This specification is under the jurisdiction of ASTM Committee C16 on Thermal Insulation and is the direct responsibility of Subcommittee C16.40 on Insulation
Systems.

3. Terminology
3.1 Definitions:
3.1.1 Definitions in Terminology C168 apply to terms used in this specification.
3.1.2 laminate jacket, n—a thin, flexible sheet material intended for use as a jacket over thermal insulation on pipe, duct, or
equipment, and consisting of multiple layers of plastic film and foil bonded together.
3.1.2.1 Discussion—
A laminate jacket is available with or without a factory applied pressure sensitive adhesive.
3.1.2.2 Discussion—
While laminate jacket is commercially available in different widths, it typically is provided commercially in approximately the
same width as pipe insulation sections.
3.1.3 laminate tape, n—a thin, flexible sheet material intended for use as a tape to seal and secure a compatible laminate jacket
over thermal insulation on pipe, duct, or equipment.
3.1.3.1 Discussion—
Laminate tape always has a factory applied, pressure sensitive adhesive which first requires removal of a release liner.
3.1.3.2 Discussion—
Laminate tape is commercially available in several different widt
