Thermoplastics piping systems for underground non-pressure applications. Test method for leaktightness of elastomeric sealing ring type joints. | Status: Superseded, Withdrawn

1 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:

1. a) Condition A: without any additional diametric or angular deflection;
2. b) Condition B: with diametric deflection;
3. c) Condition C: with angular deflection;
4. 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.
