Over deze norm
1.1 This specification covers two grades of extruded preformed flexible cellular polyolefin thermal insulation. Grade 1 is for operating temperatures from –150°F to 200°F (–101°C to 93°C). Grade 2 is for operating temperatures from –297°F to 250°F (–182°C to 121°C). For specific applications, the actual temperature limit shall be agreed upon between the manufacturer and the purchaser.
1.2 The use of thermal insulation materials covered by this specification are governed by codes and standards that address fire performance. Contact manufacturer for specific performance of product at the intended use thickness.
1.3 This specification covers the physical properties of preformed flexible cellular polyolefin thermal insulation, which have been deemed mandatory for thermal design. Physical properties such as density and coefficient of thermal expansion (CTE) have been deemed nonmandatory for thermal design. Nonmandatory physical properties have been included in Appendix X1 for information purposes only.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
