ASTM C1482-24e1

Annotation of standard text ASTM C1482-24e1 :

This specification covers the composition and physical properties of lightweight, flexible open-cell polyimide foam insulation intended for use as thermal and sound-absorbing insulation for a certain temperature range in commercial and industrial environments. The insulations are classified into the following types: Types I, II, III, IV, V, and VI. Polyimide foam shall be manufactured from the appropriate monomers, and necessary compounding ingredients. Different test methods shall be performed in order to determine the following properties of the insulation: density, apparent thermal conductivity, upper temperature limit, high temperature stability, compressive strength, compression deflection, compression set, steam aging, corrosiveness, chemical resistance, surface burning characteristics, radiant panel surface flammability, vertical burn, heat release rate, specific optical smoke density, hydrogen halides in smoke, toxic gas generation, and sound absorption coefficients.
