19、oreword This document (EN 14758-1:2012) 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 b
20、y endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the latest by September 2012.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 responsibl
21、e for identifying any or all such patent rights. This document supersedes EN 14758-1:2005+A1:2009. In this revised 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 resu
22、lts of the work undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“, which 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 mad
23、e throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommended practice for installation. EN 14758 consists of the following parts under the general title Plastics piping systems for non-pressure underground drainage and sew

According to the CEN
25、/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lit

DIN EN 14758-1:2012-05 EN 14758-1:2012 (E) 5 1 Scope This European Standard specifies the requirements for solid-wall pipes, fittings and the syst
27、em of piping systems made from mineral modified polypropylene materials (PP-MD) in the field of non-pressure underground 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
28、structure (application area code “D“) and outside the building structure. This is reflected in the marking of products 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
29、 pipe series/stiffness classes and gives recommendations concerning colours. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation pr
30、actices or codes. In conjunction with Part 2 and Part 3 of EN 14758 (see Foreword) it is applicable to PP-MD pipes 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-pres
31、sure underground drainage and sewerage. This European Standard is applicable to PP-MD pipes with or without an integral 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 cod
32、e “D“ are given in Table 4, Table 7 and Table 13. NOTE 4 Pipes, fittings and other components conforming to any of 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 giv
