Application Summary AI generated

This standard specifies a discoloration method for determining the thermal stability of poly(vinyl chloride) (PVC) and related chlorine-containing homopolymers, copolymers, and their compounds. It is applied in the rubber and plastics industry to assess material degradation under heat, particularly for quality control and formulation development of PVC-based products. The test is used to evaluate how long a material can withstand processing or service temperatures before visible color change indicates decomposition.
