C612-93 Standard Specification for Mineral Fiber Block and Board Thermal Insulation

1. Scope

1.1 This specification covers the composition, dimensions, and physical properties of mineral fiber (rock, slag, or glass) board insulation for use on cooled surfaces and on heated surfaces up to 1800°F (982°C). 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 board is primarily parallel to the surface. 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.

1.3 For satisfactory performance, properly installed protective vapor retarders must be used in low-temperature 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 values shown in parentheses are provided for information only.

1.5 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.

1.6 This standard does not purport to address all of the safety problems, 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.
