1.1 This practice lists significant properties of thermal insulation jacketing materials and test methods for determining them. 1.2 This practice applies to jacketing materials applied over thermal insulation for piping, ducts, and equipment operating at temperatures from -40 to 1200°F (-40 to 649°C), ambient temperatures from -60 to 130°F (-51 to 54°C), and surface temperatures from -60 to 200°F (-51 to 93°C). 1.3 This practice includes jacketing materials used over thermal insulation whether the insulation be in the form of rigid pipe or board, semirigid or blanket, or field applied materials that are self-supporting, including cements. 1.4 This practice does not include covers or other retaining walls that contain loose fill, other nonsupporting insulation materials, or conduits or containers for buried insulation systems. 1.5 This practice does not include mastics and coatings and their reinforcements. 1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.7 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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. |
