Scope

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 specified in the referring standard.
