SIST EN 12201-1:2011
4 Introduction The System Standard, of which this is Part 1, specifies the requirements for a piping system and its components when made from polyethylene (PE). The piping system is intended to be used for water supply intended for human consumption, including the conveyance of raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the products covered by EN 12201 (all parts): a) this standard provides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) products intended for use in water supply systems must comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. NOTE On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact with drinking water. In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EEC) and for the revision of drinking water directive (98/83/EC). If relevant, when the outputs of these processes will be known, European Product Standards will be amended by the addition of an Annex Z under Mandate M136 which will contain formal references to the applicable requirements. Until such amendments, the current national regulations remain applicable. Requirements and test methods for components of the piping system are specified in EN 12201-2:2011, EN 12201-3:2011 and prEN 12201-4:2011. Characteristics for fitness for purpose are covered in EN 12201-5:2011.[1] CEN/TS 12201-7 [2] gives guidance on the assessment of conformity. This Part of EN 12201 covers the general aspects of the plastics piping system. SIST EN 12201-1:2011
It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 2 to 5 of EN 12201, it is applicable to PE pipes, fittings, valves, their joints and to joints with components of other materials intended to be used under the following conditions: a) allowable operating pressure, PFA, up to 25 bar 1); b) an operating temperature of 20 °C as a reference temperature; c) buried in the ground; d) sea outfalls; e) laid in water; f) above ground, including pipes suspended below bridges. NOTE 2 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see Annex A. EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements concerning colours and additives. NOTE 3 It is the responsibility 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
