1.1 This specification covers the requirements for all metal prefabricated, reflective insulation systems for equipment and piping operating at temperatures above ambient in air. Typical applications are in nuclear power-generating plants and industrial plants.

1.2 Reflective insulation is thermal insulation that reduces radiant heat transfer across spaces by the use of surfaces of high reflectance and low emittance.

1.3 The values stated in inch-pound units are to be regarded as the standard. the values given in parentheses are for information only.

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