    1. Scope

    1.1 This specification addresses flexible protective jackets, made of a modified asphalt or butyl rubber sealing compound, for use over thermal insulation. The sealing compound is covered with an outer surface material. Typical applications are insulated ducts, pipe, and equipment. These materials shall be used only for outdoor or direct burial applications.

    1.2 The jacket materials covered by this specification have an allowed exposure temperature range, after installation, from –25°F to 284°F (–32°C to 140°C).

    1.3 This specification does not address installation methods of this jacketing material.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 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.
