ASTM C612-00

Standard Specification for Mineral Fiber Block and Board Thermal Insulation

SCOPE
1.1 This specification covers the classification, composition, dimension, and physical properties of mineral fiber (rock, slag, or glass) semirigid and rigid board insulation for the use on cooled surfaces and on heated surfaces up to 1800oF (982oC). For specific applications, the maximum and minimum temperature limits shall be agreed upon between the supplier and the purchaser.
1.2 The orientation of the fibers within the boards is primarily parallel to the principal surface (face). This specification does not cover fabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide a fiber orientation that is perpendicular to the principal large surface (face).
1.3 For satisfactory performance, properly installed protective vapor retarders must be used in low-temperature (below ambient) applications to prevent movement of water vapor through or around the insulation towards the colder surface.
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units are given in parentheses for information only and may be approximate.
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.
