22、 This document (EN 12201-5:2011) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endor

23、sement, at the latest by March 2012, and conflicting national standards shall be withdrawn at the latest by March 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifyi

24、ng any or all such patent rights. This document supersedes EN 12201-5:2003, EN 13244-5:2002. System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“, which is a Technical Committee of the International Org

25、anization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the system Standard.

31、gdom. BS EN 12201-5:2011EN 12201-5:2011 (E) 4 Introduction The System Standard, of which this is Part 5, specifies the requirements for a piping system and its components when made from polyethylene (PE). It is intended to be used for water supply intended for human consumption, including the convey

32、ance of raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by EN 12201 (all parts): a) this standard prov

33、ides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) products intended for use in water supply systems must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drink

34、ing water. NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water. In parallel, EC Commission has launched processes for

35、 a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC). If relevant, when the ouputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Manda

36、te M136 which will contain formal references to the applicable requirements. Until such amendments, the current national regulations remain applicable. Requirements and test methods for components of the piping system are specified in EN 12201-1, EN 12201-2, EN 12201-3 and prEN 12201-4:2011. CEN/TS

37、12201-7 1 gives guidance for the assessment of conformity. This Part of EN 12201 covers the characteristics of the fitness for purpose of the system. BS EN 12201-5:2011EN 12201-5:2011 (E) 5 1 Scope This Part of EN 12201 specifies the characteristics of the fitness for purpose of the assembled piping

38、 systems intended for the conveyance of water intended for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. It also specifies the method of preparation of test piece joints, and the tests to be carried out on t

39、hese joints for assessing the fitness for purpose of the system under normal and extreme conditions. NOTE 1 For PE components intended for the conveyance of water for human consumption and raw water prior to treatment attention is drawn to the introduction of this part of EN 12201. Components manufa

40、ctured for water for other purposes may not be suitable for water supply for human consumption. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1 to 4 of EN 12201 it is applicable to PE pipes, fittings, valves, their joints and to jo

41、ints with components of other materials intended to be used under the following conditions: a) allowable operating pressure, PFA, up to 25 bar 1); b) an operating temperature of 20 C as a reference temperature. c) buried in the ground; d) sea outfalls; e) laid in water; f) above ground, including pi

42、pes suspended below bridges. NOTE 2 For applications operating at constant temperatures greater than 20 C up to 40 C, see Annex A of EN 12201-1:2011. EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives. NOTE 3 It is the respons

43、ibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes. 2 Normative references The following referenced documents are indispen
