No existing British Standard is superseded by this standard. It is incorporated into BS 2782-11, s of testing plastics Part 11 Thermoplastics pipes, fittings and valves, as 1123E 2000, for association with related test s for plastics materials and plastics piping components. The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastics piping systems and components, to Subcommittee PRI/88/4, s of test for plastics piping systems and components, which has the responsibility to aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests ined; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled International Standards Correspondence Index, or by using the Find facility of the BSI Standards Electronic Catalogue. Warning This British Standard, which is identical with EN ISO 13845 2000, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974 and subsequent legislation. Attention should be paid to any appropriate safety precautions and the should be operated only by trained personnel. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2000, and conflicting national standards shall be withdrawn at the latest by October 2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is based on a new working draft, prepared by the International Organization for Standardization ISO. It is recast of the text concerned ISO/TC138/SC2/N673 revised without modification of the technical content. The material-dependent parameters and/or perance requirements are incorporated in the System Standards concerned. This standard is one of a series of standards on test s which support System Standards for plastics piping systems and ducting systems.

It is also applicable to elastomeric-sealing-ring-type sockets made of ductile cast iron for use with PVC-U pressure piping. 2 Principle A joint assembly as test piece consisting of a PVC-U pipe mounted into a PVC-U socket is subjected, within a specified temperature range, to a specified internal pressure regime for a specified test period whilst the pipe is also subject to an angular deflection in the socket. While under pressure the test piece is monitored for signs of leakage. NOTE It is assumed that the following test parameters are set by the standard making reference to this standard a the test pressure and pressure/time regime see 3.2 and 5.6; b the number of test pieces to be used see 4.2. 3 Apparatus 3.1 Framework, comprising at least two fixing devices, one of which is movable to allow angular deflection to be applied to the pipe within the socket. A typical arrangement is shown in figure 1. dnis the nominal outside diameter of the pipe Lis the free length of the pipe section [L 5dn min. 500 mm and max. 1500 mm] 1is the reference point for measuring and adjusting the angle of deflection 2 Figure 1 Typical Arrangement for test apparatus WARNING For safety reasons, adequate measures should be taken in design and operation of the equipment, especially for large test piece sizes.

The assembly shall be carried out in accordance with the socket manufacturers instructions. A pipe of the same nominal pressure as that of the socket shall be used for the test. The length of the pipe section shall be such that the free length, L, between the socket mouth and the end-seal is equal to five times the nominal outside diameter, dn, of the pipe with a minimum of 500 mm and a maximum of 1500 mm. NOTE The mean outside diameter, dem, of the pipe should preferably con 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 con to the maximum values stated by the manufacturer, in order to have dimensions as close as possible to the extreme limits of their relevant tolerances. 4.2 Number The number of test pieces shall be as specified in the referring standard. 5 Procedure 5.1 Secure the socket, without any deation, to the solid framework and align the pipe section with the axis of the socket. 5.2 By inclining the pipe in the test apparatus, determine the free angle of deflection, , which the joint can tolerate without the application of force. If 2, firmly anchor the pipe to maintain the deflected pipe in this position for the remainder of the test. If 2, carry out the test at a deflection of 2 by forcing the pipe to that degree of deflection. 5.3 Fill the test piece with water at a temperature of 20 5 C and release any trapped air. 5.4 Condition the test piece for a period of at least 20 min to ensure equalisation of temperature. 5.5 While testing in accordance with 5.6 a maintain the ambient temperature within 5 C of any temperature between 15 C and 25 C; Licensed Copy Institute Of Technology Tallaght, Institute of Technology, Sun Oct 08 002628 BST 2006, Uncontrolled Copy, c BSI w w w . b z f x w . c o m Page 5 EN ISO 138452000 b examine the joint during the whole test cycle and record any sign of leakage. 5.6 Unless otherwise specified in the standard referring to this test , apply the hydrostatic pressure test regime shown in Figure 2 so that the specified static pressures are maintained within a permitted deviation of 5 0 . fis the factor to be applied to PN during the test NOTE The pressure changes need not be at a linear rate.
