27、5:2015Plastics piping systems Elastomeric-sealing-ring-type socket joints for use with thermoplastic pressure pipes Test method for leaktightness under internal pressure and with angular deflectionWARNING Persons using this International Standard should be familiar with normal laboratory practice, i
28、f applicable. The use of this International Standard may involve hazardous materials, operations, and equipment. This International Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this International Standard to
29、 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1 ScopeThis International Standard specifies a method for testing the leak tightness under internal pressure with angular deflection of assembled joints between elastomeric-seali
30、ng-ring-type sockets made of plastic or metal and plastic pressure pipes.2 PrincipleA joint assembly as test piece consisting of a plastic pipe mounted into a socket is subjected, within a specified temperature range, to a specified internal pressure regime for a specified test period while the pipe
31、 is also subject to an angular deflection in the socket. While under pressure, the test piece is monitored for signs of leakage.3 Test parameters and requirementsThe test parameters of the International Standard which refers to this test International Standard shall be used and the requirements shal
32、l be fulfilled. If one or more parameters are not given in the referring International Standard, the ones given in Annex A shall apply.NOTE The following test parameters should be given by the International Standard which refers to this test International Standard:a) test medium;b) test pressure bar
33、 or MPa;c) test duration h;d) test temperature C;e) angle of deflection () ;f) free length mm.4 Apparatus4.1 Framework, comprising at least two fixing devices, one of which is movable to allow angular deflection to be applied to the test joint.

For practical reasons, the manufact
37、urer can wait a shorter time before testing. In case of dispute, a duration of 24 h shall apply.The assembly shall be carried out in accordance with the socket manufacturers instructions.A pipe of the same nominal pressure (PN) or the same pipe series S as that of the socket shall be used for the te
38、st.The mean outside diameter, dem, of the pipe should preferably conform to the minimum specified value, and the socket dimensions (mean inside diameter, dim, and the diameter of the groove for housing the sealing ring) should preferably conform to the maximum values stated by the manufacturer, in o
39、rder to have dimensions as close as possible to the extreme limits of their relevant tolerances.6 Procedure6.1 Secure the socket, without any deformation, to the solid framework and align the pipe section with the axis of the socket.6.2 By inclining the pipe in the test apparatus, determine the free
40、 angle of deflection, free, which the joint can tolerate without the application of force.If the free angle of deflection is greater or equal to the required one, firmly anchor the pipe to maintain the deflected pipe in this position for the remainder of the test.2 ISO 2015 All rights reservedBS EN
41、ISO 13845:2015ISO 13845:2015(E)If the free angle of deflection is less than the required one, carry out the test at the required deflection measured at the starting point (see Figure 1), by forcing the pipe to that position.6.3 Fill the test piece with the test medium at the specified temperature. I
42、f water is used as test medium, ensure all air is removed and excluded from the test piece for the remainder of the procedure.6.4 Condition the test piece to ensure equalization of temperature.Minimum conditioning times are given in Table 1.Table 1 Conditioning periodsNominal wall thickness of the p
