Scope

This European standard specifies three basic test pressures for determining the leaktightness of elastomeric sealing ring type joints for buried thermoplastics non-pressure piping systems. Unless otherwise specified in the referring standard, the methods pressures used are the following: - p1: internal negative air pressure (partial vacuum); - p2: a low internal hydrostatic pressure; - p3: a higher internal hydrostatic pressure. It also describes four test conditions under which the test can be executed, as follows: A: without any additional diametric or angular deflection; B: with diametric deflection; C: with angular deflection; D: with simultaneous angul
