ASTM C764-04

Standard Specification for Mineral Fiber Loose-Fill Thermal Insulation

SCOPE
1.1 This specification covers the composition and physical properties of nodulated mineral fiber thermal insulation for use in attics or enclosed spaces in housing and other framed buildings.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only.
1.3 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.
