DIN EN 12201-4:2012-04 EN 12201-4:2012 (E) 4 Introduction This European S

24、tandard, known as the System Standard, 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

25、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 product covered by EN 12201: a) this European Standard provides no information as to whether the products may be

26、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

27、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 sub

28、stituted to CP directive (89/106/EC) 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 M/136 which will contain formal references to the a

29、pplicable requirements. Until such amendments, the current national regulations remain applicable. Requirements and test methods for material and components, other than valves, are specified in EN 12201-1:2011, EN 12201-2 and EN 12201-3:2011. Characteristics for fitness of purpose are covered in EN

30、12201-5. CEN/TS 12201-7 1 gives guidance for the assessment of conformity. This Part of EN 12201 covers the characteristics of valves. DIN EN 12201-4:2012-04 EN 12201-4:2012 (E) 5 1 Scope This Part of EN 12201 specifies the characteristics of valves or valve bodies made from polyethylene (PE 100 and

31、 PE 80) for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes. NOTE 1 For valves or valve bodies intended for drainage and sewerage u

32、nder pressure, additional specifications/tests may be necessary according to the requirements of the purchaser, especially for the chemical resistance of the components in contact with the fluids and functioning characteristics. NOTE 2 For PE components intended for the conveyance of water for human

33、 consumption and raw water prior to treatment attention is drawn to 5.4. Components manufactured for water for other purposes may not be suitable for water supply for human consumption. It also specifies the test parameters for the test methods referred to in this European Standard. NOTE 3 Valves ma

34、de from material other than polyethylene (PE) designed for the supply of water intended for human consumption to a relevant standard(s) can be used in PE piping systems conforming to EN 12201 when they have relevant PE connection for butt fusion or electrofusion ends (see EN 12201-3:2011). In conjun

35、ction with Parts 1, 2, 3 and 5 of EN 12201 it is applicable to PE valves, 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 t

36、emperature; c) buried in the ground; d) sea outfalls; e) laid in water; f) above ground, including pipes suspended below bridges. NOTE 4 For applications operating at constant temperature greater than 20 C and up to 40 C, see EN 12201-1:2011, Annex A. EN 12201 covers a range of allowable operating p

37、ressures and gives requirements concerning colours and additives. NOTE 5 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

38、practices or codes. This Part of EN 12201 covers valves for pipes with a nominal outside diameter dn 315 mm. 1) 1 bar = 0,1 MPa = 105Pa; 1 MPa = 1 N/mm2.
