1.1 The specification covers the physical properties of self-supported spray applied cellulosic fibers intended for use as thermal or acoustical insulation, 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 When the installation or use of insulation materials, accessories, and systems may pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the recommended use of the company's products, and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
1.6 This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices prior to use.
