18、ystems 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of an identical text or by endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the l

19、atest by September 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 identifying any or all such patent rights. This document supersedes EN 14758-1:2005+A1:2009. In this rev

20、ised document the following changes are made: relevant test methods are changed from EN to ISO versions; the long term durability test are removed. The System Standards are based on the results of the work undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“, wh

21、ich is a Technical Committee of the International Organization for Standardization (ISO). The System Standards are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional req

22、uirements and on recommended practice for installation.

BS EN 14758-1:2012EN 14758-1:2012 (E) 5 1 Scope This European Standard specifies the requirements for solid-wall pipes, fittings and the system of piping systems made from mineral modified polypropylene materials (PP-MD) in the field of non-pressure underg

26、round drainage and sewerage outside the building structure (application area code “U“), and non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D“) and outside the building structure. This is reflected in the marking of produ

27、cts by “U“ and “UD“. It also specifies the test parameters for the test methods referred to in this European Standard. This European Standard covers a range of nominal sizes, a range of pipe series/stiffness classes and gives recommendations concerning colours. NOTE 1 It is the responsibility of the

28、 purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with Part 2 and Part 3 of EN 14758 (see Foreword) it is applicable to PP-MD pipes

29、and fittings, their elastomeric sealing ring joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage. This European Standard is applicable to PP-MD pipes with or without an inte

30、gral socket. NOTE 2 The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings. NOTE 3 Requirements and limiting values for application area code “D“ are given in Table 4, Table 7 and Table 13. NOTE 4 Pipes, fittings and other components conforming to any of

31、the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this European Standard, when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 13. 2 Normative references The following documents, in whole or in
