This Technical Specification can be used to support the elaboration of national third party certification procedures for products coning 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 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 Standardization ISO. They are supported by separate standards on test s to which references are made throughout the System Standard. The System Standards are consistent with standards on general functional requirements and standards on recommended practice for installation. EN 12201 consists of the following Parts, under the general title “Plastics piping systems for water supply Polyethylene PE“. Part 1 General Part 2 Pipes Part 3 Fittings Part 4 Valves Part 5 Fitness for purpose of the system Part 7 Guidance for the assessment of conity this Technical Specification NOTEIt was decided not to publish a Part 6 Recommended practice for installation. Instead, existing national installation practices would be applicable. This Part of EN 12201 includes the following Annex A Normative Change of PE compound Annex B Normative Change of design Bibliography System Standards for piping systems of other plastics materials used for the conveyance of water under pressure include the following EN 1452, Plastics piping systems for water supply Unplasticized polyvinyl chloride PVC-U EN 1796, Plastics piping systems for water supply with or without pressure Glass-reinforced thermosetting plastics GRP based on unsaturated polyester resin UP According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this CEN Technical Specification Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

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 ination as to whether the product may be used without restriction in any Member States 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 assessment of conity of materials, components, joints and assemblies and is intended to be used by certification bodies, inspection bodies, testing laboratories and manufacturers.

This Technical Specification includes a requirements for materials, components, joints and assemblies given in Parts 1 to 5 of EN 12201; b requirements for the manufacturers quality system; NOTE 1It is recommended that the quality system cons to EN ISO 90012000 [1] c definitions and procedures to be applied if third party certification is involved. NOTE 2If third party certification is involved, it is recommended that the certification body is accredited to EN 45011[2] or EN 45012[3], as applicable. In conjunction with one or more Parts of EN 12201 see Foreword it is applicable to polyethylene PE piping systems intended to be used for water supply intended for human consumption including the conveyance of raw water prior to treatment. 2 Normative references This Technical Specification incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter.
