Standard Specification for Polyimide Rigid Cellular Thermal Insulation
|Publication Date:||15 December 2011|
This specification covers the composition and physical properties of polyimide foam insulation with nominal densities from 1.0 lb/ft3 to 8.0 lb/ft3 (16 kg/m3 to 128 kg/m3) and intended for use as thermal and sound-isolating insulation for temperatures from −423°F to +600°F (−253°C to +316°C) in commercial and industrial environments.
The annex shall apply to this specification for marine applications.
This standard is designed as a material specification and not a design document.
The values stated in Table 1 and Table 2 are not to be used as design values. It is the buyer's responsibility to specify design requirements and obtain supporting documentation from the material supplier.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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 requirements prior to use.
NOTE 1-The subject matter of this material specification is not covered by any other ASTM specification. There is no known ISO standard covering the subject of this standard.
