This document specifies a test method 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 tests are carried out at the following basic test pressures:
— p1: internal negative air pressure (partial vacuum);
— p2: a low internal hydrostatic pressure;
— p3: a higher internal hydrostatic pressure.
It also describes the following four test conditions under which the tests are performed:
a) Condition A: without any additional diametric or angular deflection;
b) Condition B: with diametric deflection;
c) Condition C: with angular deflection;
d) Condition D: with simultaneous angular and diametric deflection.
The applicable selection of the test pressure(s) and the test condition(s) is/are specified in the referring standard.
