1.1 This specification covers two grades of preformed flexible cellular non-crosslinked 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 -40°F to 158°F (-40°C to 70°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 may be governed by building codes that address fire performance.

1.3 This specification covers the physical properties of preformed flexible cellular non-crosslinked 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 the standard. The metric unit equivalents of inch-pound units, given in parentheses, may be approximate.

1.5 The following safety hazards caveat pertains only to the test methods portion, Section 11, 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.
