The Committee would like to point out
7、the provisions regarding the colour of pipes intended to convey water for human consumption (see Subclause 5.2) applicable in Germany as laid down in the body of technical rules and standards for gas and water issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and S
8、cientific Association for Gas and Water). According to DVGW GW 335-A2 the following colours apply: Pipes Stripes Outer peelable layer Outer coextruded layer PE 80 black RAL 9004 Light blue RAL 5012 PE 100 royal blue RAL 5005 PE 100 black RAL 9004 Royal blue RAL 5005 Royal blue RAL 5005 Royal blue RA
9、L 5005 The colours of the outer surfaces should be roughly equivalent to the specified RAL colours (see table). In Germany, blue or black with blue stripes normally indicate pipes intended for drinking water. Amendments This standard differs from DIN EN 12201-2:2011-11 as follows: a) wall thicknesse

DIN EN 12201-2:2013-12 EN 12201-2:2011+A1:2013 (E) 5 Introduction The System Standard, of which this is Part 2, specifies the requirements for a piping system and its components when made
37、 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 effec
38、ts on the quality of water intended for human consumption, caused by the product covered by EN 12201 (all parts): a) this standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; b) products intended for use in water su
39、pply 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 method
40、s 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,
41、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
42、 and test methods for material and components, other than pipes, are specified in EN 12201-1:2011, EN 12201-3:2011 1 and prEN 12201-4:2011 2. Characteristics for fitness of purpose are covered in EN 12201-5:2011 and CEN/TS 12201-7 3 gives guidance for the assessment of conformity. This Part of EN 12
43、201 covers the characteristics of pipes. DIN EN 12201-2:2013-12 EN 12201-2:2011+A1:2013 (E) 6 1 Scope This part of EN 12201 specifies the characteristics of pipes made from polyethylene (PE 100, PE 80 and PE 40) for buried and above ground applications, intended for the conveyance of water for human
44、 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 5.3 of this European Standa
45、rd. Components manufactured for water for general 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 Part 1 and Parts 3 to 5 of EN 12201, it is applic
46、able to PE pipes, 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 outfalls;
47、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 of EN 12201-1:2011. NOTE 3 Pipes constructions including barrier layers are not covered by this document. EN 12201 cove
48、rs a range of allowable operating pressures and gives requirements concerning colours and additives. It covers three types of pipe: PE pipes (outside diameter dn) including any identification stripes; PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total out
49、side diameter dn) as specified in Annex B, where all layers have the same MRS rating; PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (coated pipe) as specified in Annex C. NOTE 4 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 installat
