Scope1.1 This specification covers structural insulating board forgeneral thermal insulating, fire-resistive, and marine bulkheadapplications. Th

3、e rigid, preformed structural insulating board isfor use at temperatures up to 1700F (927C). For specificapplications, the actual temperature limit shall be agreed uponbetween the manufacturer and the purchaser.1.2 The structural insulating board maintains its structuralintegrity after immersion in

4、water.1.3 Rapid cycling over a wide temperature range is notrecommended because of potential damage due to thermalshock.1.4 The values stated in inch-pound units are to be regardedas the standard. The approximate SI equivalents of inch-poundunits are given in parentheses.1.5 This standard does not p

5、urport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.6 When the installation or use of thermal

6、 insulationmaterials, accessories and systems, may pose safety or healthproblems, the manufacturer shall provide the user appropriatecurrent information regarding any known problems associatedwith the recommended use of the companys products, andshall also recommend protective measures to be employe

7、d intheir safe utilization. The user shall establish appropriate safetyand health practices and determine the applicability of regula-tory requirements prior to use.2.
