Someof the chemicals listed could be deleterious to a specificcompound, causing radical changes in the physica

When service conditions include stress or otherfactors, or both, test chemical resistance of the PVC/CPVCcompound under actual service conditions.1This classification is under the jurisdiction of ASTM Committee
