significance And Use:

scope:

1.1 This guide provides information to manufacturers for the development of a loose-fill thermal insulation product coverage chart. This guide is limited to developing a coverage chart from density versus thickness, apparent thermal conductivity versus density, and thickness versus area mass relationships obtained through product testing.

1.2 This guide applies to a wide variety of loose-fill thermal insulation products including mineral fiber (Specification C 764), or cellulosic fiber (Specification C 739) materials; granular types including vermiculite (Specification C 516) and perlite (Specification C 549); pelletized products; and any other insulation material that can be installed pneumatically or poured in place.

1.3 Coverage charts for loose-fill insulation products are required by regulation under the United States Federal Trade Commissions 16CFR Part 460. Other countries or local governing agencies may have coverage chart requirements in addition to, or that differ from, those presented in this guide; see the Appendix for examples.

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

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