Annotation of standard text ASTM C1534-26 :

This specification covers the composition, dimensions, and physical properties of flexible unfaced foam sheet, used to insulate interior surfaces of HVAC ducts, plenums and equipment used for the distribution of conditioned air. The flexible polymeric insulations of this specification are classified into Types I and II. Type I is a closed flexible foam. Type II is an open cell flexible foam. Following test methods shall be performed: apparent thermal conductivity; surface burning characteristics; hot service performance; water vapor sorption; water absorption; dimensional stability; odor emission; fungi resistance; erosion resistance; and sound absorption coefficient.
