This standard specifies a method for testing the leaktightness of assemblies of unplasticized poly(vinyl chloride) (PVC-U) pipes with elastomeric sealing-ring-type socket joints including: - single sockets of pipes; - double sockets; - sockets of fittings. It is also applicable to elastomeric-sealing-ring-type sockets made of ductile cast iron for use with PVC-U pressure piping.
