ActivePlastics piping systems--Elastomeric-sealing-ring-type socket joints of unplasticized poly(vinyl chloride)(PVC-U)for use with PVC-U pipes--Test method for leaktightness under negative pressure
塑料管道系统 硬聚氯乙烯(PVC-U)管材弹性密封圈式承口接头 负压密封试验方法
Application Summary AI generated
This standard specifies the test method for evaluating the leaktightness of elastomeric-sealing-ring-type socket joints in unplasticized poly(vinyl chloride) (PVC-U) piping systems when subjected to negative (vacuum) pressure. It is applied in the quality control and performance testing of PVC-U pipe joints used in gravity drainage, sewerage, and low-pressure fluid transport systems, ensuring the joint remains sealed under internal vacuum conditions that may occur during operation.
