ASTM C578-03a

Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation

SCOPE
1.1 This specification covers the types, physical properties, and dimensions of cellular polystyrene intended for use as thermal insulation for temperatures from -65 to + 165°F (-53.9 to + 73.9°C).
1.1.1 For Type XIII only, this specification covers the physical properties, and dimensions of cellular polystyrene intended for use as thermal insulation for temperatures from -297 to +165°F (-183 to +73.9°C).
1.2 Consult the manufacturer for specific recommendations and properties in cryogenic conditions.
1.2.1 This specification does not cover cryogenic properties except for the k-factors for Type XIII in . For Type XIII in specific cryogenic applications, the manufacturer and purchaser shall agree upon the actual temperature limits and physical property requirements in addition to the k-factors in Appendix X1.
1.3 The use of thermal insulation materials covered by this specification may be regulated by building codes that address fire performance. For some end uses, specifiers should also address the effect of moisture. Guidelines regarding these end use considerations are included in Appendix X1.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.5 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.
