Annotation of standard text ČSN EN ISO 13259 (646459):
This International Standard specifies three basic test pressures 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 methods use the following pressures: p1: internal negative air pressure (partial vacuum); p2: low internal hydrostatic pressure; p3: higher internal hydrostatic pressure. It also describes the following four conditions under which the test can be executed: a) A: without any additional diametric or angular deflection; b) B: with diametric deflection; c) C: with angular deflection; d) D: with simultaneous angular and diametric deflection. These conditions can be applied individually or in combination. The applicable selection of the method(s) and the condition(s) should be specified in the referring standard
