11、sing the “Search” facility of the BSI Electronic Catalogue or of British Standards Online. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Attention is drawn to the following statutory regulations: Health and
12、 Safety at Work etc. Act 1974 and subsequent regulations. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because this is not a full European standard and under CEN rules member bodies
13、 have only to announce that it is available; however, the DD documents are an accepted means of announcing that the CEN/TS is available. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of t
14、his Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken
15、on its status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support th
16、e conversion into a European standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee PRI/88/2 at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document reference and cla

28、N. This Technical Specification can be used to support the elaboration of national third party certification procedures for products conforming to the applicable Parts of EN 12201. This Technical Specification is a Part of a System Standard for plastics piping systems of a particular material for a
29、specified application. There are a number of such System Standards. 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 Standardiza
30、tion (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard.

36、CEN/TS 12201-7:2003 (E) 4 Introduction The System Standard, of which this is Part 7, specifies the requirements for a piping system and its components made from polyethylene (PE), intended to be used for water supply intended for human consumption including the conveyance of raw water prior to treat
37、ment. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this Technical Specification: 1) This Technical Specification provides no information as to whether the product may be used without restriction in any Member States
38、of the EU or EFTA; 2) It should be noted that, while awaiting adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. This Part of EN 12201 gives guidance for the procedures and requirements for the assess
39、ment of conformity of materials, components, joints and assemblies and is intended to be used by certification bodies, inspection bodies, testing laboratories and manufacturers.
