DIN EN 12201-3:2013-01 EN 12201-3:2011+A1:2012 (E) 6 Introduction The System Standard, of which this is
33、 Part 3, specifies the requirements for a piping system and its components when made from polyethylene (PE), 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
34、water for other purposes. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by EN 12201 (all parts): a) this European Standard provides no information as to whether the products may be used without restriction in any of the
35、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 p
36、ropose 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) a
37、nd for the revision of drinking water directive (98/83/EC). If relevant, when the ouputs 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 amend
38、ments, the current national regulations remain applicable. Requirements and test methods for material and components, other than fittings, are specified in EN 12201-1, EN 12201-2 and prEN 12201-4:2011. Characteristics for fitness of purpose are covered in EN 12201-5. CEN/TS 12201-7 2 gives guidance
39、for the assessment of conformity. This Part of EN 12201 covers the characteristics of fittings. DIN EN 12201-3:2013-01 EN 12201-3:2011+A1:2012 (E) 7 1 Scope This !European Standard“ specifies the characteristics of fittings made from polyethylene (PE 100 and PE 80) intended for the conveyance of wat
40、er for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. NOTE 1 For PE components intended for the conveyance of water for human consumption and raw water prior to treatment, attention is drawn to 5.6 of this pa
41、rt of EN 12201. Components manufactured for water for other purposes, drainage and sewerage may not be suitable for water supply for human consumption. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2 ,4 and 5 of EN 12201, it is
42、applicable to PE fittings, their joints and to joints with components of PE and 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 o
43、utfalls; e) laid in water; f) above ground, including pipes suspended below bridges. NOTE 2 For applications operating at constant temperature greater than 20 C and up to 40 C, see Annex A of EN 12201-1:2011. EN 12201 (all parts) covers a range of allowable operating pressures and gives requirements
44、 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. These fitti
45、ngs can be of the following types: a) fusion fittings; 1) electrofusion fittings; 2) spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion); 3) socket fusion fittings (see Annex A); b) mechanical fittings; 1) compression fittings; 2) flanged fittings; c) fabricated
46、fittings (see Annex B). 1) 1 bar = 0,1 MPa = 105Pa; 1 MPa = 1 N/mm2.DIN EN 12201-3:2013-01 EN 12201-3:2011+A1:2012 (E) 8 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
