硬聚氯乙烯(PVC-U) 管材 二氯甲烷浸渍试验方法
Application Summary AI generated
This standard specifies a test method for determining the resistance of unplasticized polyvinyl chloride (PVC-U) pipes to dichloromethane. It is applied in quality control and material verification for PVC-U pipes used in water supply, drainage, and industrial fluid transport, ensuring the pipes have adequate chemical resistance and proper processing quality. The test is conducted by immersing pipe samples in dichloromethane and observing for surface changes, such as swelling or cracking, to assess material integrity.
