This European standard specifies three basic test pressures for determining the leaktightness of elastomericsealing 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 angular and diametric deflection.These conditions can be applied individually or in combination. The applicable selection of the method(s)and the condition(s) should be specified in the referring standard.
