Thermoplastics piping systems for underground non-pressure applications. Test method for leaktightness of elastomeric sealing ring type joints
| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 18 |
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.
