ASTM C1149-02

Standard Specification for Self-Supported Spray Applied Cellulosic Thermal Insulation

SCOPE
1.1 The specification covers the physical properties of self-supported spray applied cellulosic fibers intended for use as thermal insulation or an acoustical absorbent material, or both.
1.2 This specification covers chemically treated cellulosic materials intended for pneumatic applications where temperatures do not exceed 82.2°C (180°F) and where temperatures will routinely remain below 65.6°C (150°F).
1.2.1 Type I—Material applied with liquid adhesive and suitable for either exposed or enclosed applications.
1.2.2 Type II—Materials containing a dry adhesive that is activated by water during installation and intended only for enclosed or covered applications.
1.3 This is a material specification only and is not intended to deal with methods of application that are supplied by the manufacturer.
1.4 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are 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 determine the applicability of regulatory limitations prior to use.
