ASTM E1730-99 - 10.10.1999
 
1. Scope

1.1 This specification covers rigid, closed cell, polyurethane and polyisocyanurate thermal insulation for sandwich panels used in shelter construction for exposure to ambient temperatures of -25° to 160°F (-32° to 71°C). Painted surfaces of shelters in actual field use reach temperatures of 200°F (93°C). The materials in this specification must be capable of withstanding processing, (laminating) temperatures of 110°C (230°F).

1.2 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only.

1.3 The following precautionary caveat pertains only to the test method portion, Section 12, of this specification: 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.
