ASTM C1630-24 - Standard Guide for Development of Coverage Charts for Loose-Fill Thermal Building Insulations

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 C764), or cellulosic fiber (Specification C739) materials; granular types including vermiculite (Specification C516) and perlite (Specification C549); pelletized products; and any other insulation materials that are 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 Commission’s 16 CFR 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 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.
