This specification covers the standard for high-temperature fiber blanket thermal insulation for use at various temperatures. The insulation should be tested and comply accordingly to physical and mechanical properties of the insulation such as apparent thermal conductivity, density, and temperature of use. The insulation shall also be tested for non-fibrous content, linear shrinkage, and tensile strength.

1.1 This specification covers high-temperature fiber blanket thermal insulation for use at various temperatures from 1350F (732C) up to 3000F (1649C), except when used in high-temperature furnaces.

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.

1.2 When the installation or use of thermal insulation materials, accessories, and systems may pose safety or health problems, the manufacturers shall provide the user with 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.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
