EN 12201-2:2003 (E)4IntroductionThe System Standard, of which this is Part 2, specifies the requirements for a piping system and its componentswhen made from polyethylene (PE). It is intended to be used for water supply intended for human consumption,including the conveyance of raw water prior to treatment.In respect of potential adverse effects on the quality of water intended for human consumption, caused by theproduct covered by this standard:a)
this standard provides no information as to whether the product may be used without restriction in any of theMember States of the EU or EFTA;b)
it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulationsconcerning the use and/or the characteristics of this product remain in force.Requirements and test methods for material and components, other than pipes, are specified in EN 12201-1, EN12201-3 and EN 12201-4. Characteristics for fitness of purpose are covered in EN 12201-5 and prCEN/TS 12201-7gives guidance for the assessment of conformity.This Part of this European Standard covers the characteristics of pipes.SIST EN 12201-2:2003
EN 12201-2:2003 (E)51 ScopeThis Part of this European Standard specifies the characteristics of pipes made from polyethylene (PE) intended forthe 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 other Parts of this European Standard (see Foreword) it is applicable to PE pipes, their jointsand 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 reference 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 concerningcolours and additives.NOTE 2It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account theirparticular 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 compound used for the manufacture of products to thisspecification is required in accordance with Table 2 of EN 12201-1:2003.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
