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: p 1: internal negative air pressure (partial vacuum); p 2: a low internal hydrostatic pressure; p 3: a higher internal hydrostatic pressure. It also describes the following four test conditions under which the tests are performed: Condition A: without any additional diametric or angular deflection; Condition B: with diametric deflection; Condition C: with angular deflection; 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.
