Standard Guide for Selecting Jacketing Materials for Thermal Insulation
SCOPE
1.1 This guide covers criteria for selecting thermal insulation jacketing materials and is not intended for use as a performance or product specification.
1.2 This guide applies to jacketing materials applied over thermal insulation for piping, ducts, and equipment.
1.3 This guide includes jacketing materials used over thermal insulation whether the insulation is in the form of pipe, board, or blanket, or field applied materials that are self-supporting, including insulation cements.
1.4 This guide 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 guide 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 SI values given in parentheses are for information only.
