ASTM C1071-25

Annotation of standard text ASTM C1071-25 :

This specification covers fibrous glass insulation used as a thermal and sound absorbing liner for interior surfaces of ducts, plenums, and other air handling equipment. The insulation shall be of the following types: Type I and Type II. The basic material shall be made from glass processed from the molten state into fibrous form with a binder added to form dimensionally stable insulation. The following test methods shall be performed: corrosiveness; water vapor sorption; fungi resistance; temperature resistance; erosion resistance; odor emission; surface burning characteristics; apparent thermal conductivity; sound absorption coefficients; bacteria resistance; and combustion characteristics.
