Full Description

1.1This specification covers faced or unfaced, rigid cellular phenolic thermal insulation. Boards shall be faced or unfaced. Tubular forms covered by this standard shall be unfaced. It does not apply to field expanded cellular phenolic materials.

1.2Materials covered by this specification are used as roof insulation; sheathing or rigid board for non-load bearing, building material applications; and pipe insulation for use between40 and 257F (40 and 125C). Type II and Type III materials with an appropriate vapor retarder covering on the warm surface are used to a lower temperature limit of 290F (180C). (See 7.3.)

1.3The 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.

1.4This specification covers closed cell rigid cellular phenolic thermal insulation manufactured using blowing agents with an ozone depletion potential of 0 (ODP 0).

1.5This 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.

For specific precautionary statements, see Section 16.
