Attention is also drawn to any appropriate safety precautions. It is assumed in the drafting of a standard that the execution of its provisions is entrusted to
11、 appropriately qualified people. Additional information With reference to the Introduction and 5.3, as yet there is no pan-European agreement on water quality requirements, so existing UK regulations remain in force. Regulation 25 of the Water Supply (Water Quality) Regulations 1989 specifies the ci
12、rcumstances in which water undertakers may use products in contact with water supplies in England and Wales. As part of the UK regulations, all pipes and fittings used to convey drinking water supplies are required to be approved under the provisions of Regulation 25(1) (a) or (b) as appropriate and
13、 the Water Regulation Advisory Scheme (WRAS) to ensure that their use will not cause adverse effect on water quality or a risk to health of consumers. In Scotland and Northern Ireland there are similar provisions. These regulations will be revised as necessary to comply with the EU Drinking Water Qu

26、oreword This document EN 12201-2:2003 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
27、 endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at the latest by March 2005. This standard is a Part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards
28、. 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 Organization for Standardization (ISO). They are supported by separate standards on test metho
29、ds to which references are made throughout the System Standard. The System Standards are consistent with standards on general functional requirements and standards on recommended practices for installation. This European Standard consists of the following Parts, under the general title Plastics pipi
30、ng systems for water supply Polyethylene (PE). Part 1: General. Part 2: Pipes (this standard). Part 3: Fittings. Part 4: Valves. Part 5: Fitness for purpose of the system. Part 7: Guidance for the assessment of conformity.1) NOTEIt was decided not to publish a Part 6: Recommended practice for instal
31、lation. Instead, existing national practices would be applicable. This Part of this European Standard includes the following: Annex A (informative): Relationship between PN, MRS, S and SDR; Bibliography. System Standards for piping systems of other plastics materials used for the conveyance of water
32、 include the following: EN 1452, Plastics piping systems for water supply Unplasticized poly(vinyl chloride) (PVC-U); prEN 1796, Plastics piping systems for water supply with or without pressure Glass-reinforced thermosetting plastics (GRP) based on polyester resins (UP).

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countri
34、es are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovak Republic, Spain, Sweden, Switzerland and the United Kingdom. 1) to be published a
35、s a CEN/TS. EN 12201-2:2003 (E) 4 Introduction The System Standard, of which this is Part 2, 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 conveyance of raw
36、water prior to treatment. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard: a) this standard provides no information as to whether the product may be used without restriction in any of the Member States of
37、the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Requirements and test methods for material and components, other than pipes, are speci
38、fied in EN 12201-1, EN 12201-3 and EN 12201-4. Characteristics for fitness of purpose are covered in EN 12201-5 and prCEN/TS 12201-7 gives guidance for the assessment of conformity. This Part of this European Standard covers the characteristics of pipes. EN 12201-2:2003 (E) 5 1 Scope This Part of th
39、is European Standard specifies the characteristics of pipes made from polyethylene (PE) intended for the conveyance of water for human consumption, including raw water prior to treatment. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with oth
40、er Parts of this European Standard (see Foreword) it is applicable to PE pipes, their joints and to joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure, MOP, up to 25 bar 2); b) an operating temperature of 20 C as a ref
41、erence temperature. NOTE 1For applications operating at constant temperatures greater than 20 C and up to 40 C, see annex A of EN 12201-1:2003. This European Standard covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 2It is the responsibility
42、 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. NOTE 3Assessment of the resistance to slow crack growth of the PE pipe compou
43、nd used for the manufacture of products to this specification is required in accordance with Table 2 of EN 12201-1:2003. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropria
44、te places in the text, and the publications are listed hereafter.
