28、nt 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
29、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 diametri
30、c 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.2 Normative referencesThere are no normative references in this do
