DESCRIPTION
CSN EN ISO 13259
CSN EN ISO 13259 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. Original English text of CSN EN Standard. The price of the Standard included all amendments and correcturs.
