Standard Specification for Mineral Fiber Blanket Thermal Insulation for Commercial and Industrial Applications
|Publication Date:||10 October 2002|
|ICS Code (Thermal and sound insulating materials):||91.100.60|
1.1 This specification covers the classification, composition, physical properties, and dimensions of mineral fiber (rock, slag, or glass) blanket intended for use as thermal insulation on surfaces at temperatures below ambient or above ambient up to 1200°F (649°C). For specific applications, the actual temperature limit shall be agreed upon between the supplier and the purchaser.
1.2 The orientation of the fibers within the blanket 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 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 This standard does not purport to provide the performance requirements of hourly-rated fire systems. Consult the manufacturer for the appropriate system.
1.5 The values stated in inch-pound units shall be regarded as the standard. The System International (SI) equivalents of inch-pound units are given in parentheses and are for information only and are approximate.
1.6 This standard does not purport to address all of the safety concerns 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.
