ASTM C739-03e1

Standard Specification for Cellulosic Fiber Loose-Fill Thermal Insulation

SCOPE
1.1 This specification covers the composition and physical requirements of chemically treated, recycled cellulosic fiber loose-fill type thermal insulation for use in attics or enclosed spaces in housing, and other framed buildings within the ambient temperature range from -45 to 90°C (-49 to 194°F) by pneumatic or pouring application. While products that comply with this specification may be used in various constructions, they are adaptable primarily, but not exclusively, to wood joist, rafters, and stud construction.
1.2 The values stated in SI 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.
