CEN/TC 155 Plastics piping systems and ducting systems
European Norm
23.040.80 Seals for pipe and hose assemblies
This standard specifies three basic test methods for determining the leaktightness of elastomeric sealing ring type joints for buried thermoplastics non-pressure piping systems. It also gives a combined test method where the three methods are executed successively. Unless otherwise specified in the referring standard, the methods use the following pressures respectively: - method 1: a low internal hydrostatic pressure for assessing leaktightness; - method 2: a higher internal hydrostatic pressure for assessing performance; - method 3: internal negative air pressure (partial vacuum).
