Abstract:

This specification covers the standard for the composition and physical properties of expanded perlite loose fill insulation. This specification also covers the testing procedures used in determining the acceptability of the materials which deal primarily with material performance in the temperature range associated with the thermal envelope of buildings. This specification also covers the standard for surface-treated perlite proposed for use in dust suppression. Requirements for the insulation shall include conformance to standard of the following: bulk density, grading, thermal resistance, moisture absorption, combustibility, surface burning characteristics, and dust suppression.

Scope:

1.1 This specification covers the composition and physical properties of expanded perlite loose fill insulation. The specification also includes the testing procedures by which the acceptability of the material is determined. These testing procedures deal primarily with material performance in the temperature range associated with the thermal envelope of buildings; however, the commercially usable temperature range for this insulation is from 459 to 1400°F (1 to 1033 K). For specialized applications, refer to the manufacturer's instructions.

1.2 The specification also covers the composition and properties of perlite that has been surface-treated to produce dust suppression for installations where dust is a factor.

1.3 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.

1.4 When the installation or use of thermal 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. For additional precautionary statements, see Section 12.

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.
