ASTM C1136-23

Annotation of standard text ASTM C1136-23 :

This specification covers vapor retarders for thermal insulation, specifically, flexible materials with permeance and surface burning characteristics. Vapor retarders are classified based on vapor retardance and strength properties: Types I, II, III, IV, V, and VI. The following test methods shall be performed: water vapor permeance; surface burning characteristics; tensile strength; dimensional stability; fungi resistance; thermal integrity of flexible water vapor retarders; burst strength of vapor retarders; permanence of flame retardancy; and elevated temperature and humidity resistance of vapor retarders for insulation.
