ASTM-C656 2007

1.1 This specification covers structural insulating board for general thermal insulating, fire-resistive, and marine bulkhead applications. The rigid, preformed structural insulating board is for use at temperatures up to 1700F (927C). For specific applications, the actual temperature limit shall be agreed upon between the manufacturer and the purchaser.

1.2 The structural insulating board maintains its structural integrity after immersion in water.

1.3 Rapid cycling over a wide temperature range is not recommended because of potential damage due to thermal shock.

1.4 The values stated in inch-pound units are to be regarded as the standard. The approximate SI equivalents of inch-pound units are given in parentheses.

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.

1.5 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.
