21、e for the assessment of conformity This issue of CEN/TS 12201-7 takes into account the technical changes made in the revision of EN 12201-1, EN 12201-2, EN 12201-3, EN 12201-5 and EN 12201-4, published in 2011 and respectively in 2012. Guidance for the assessment of conformity given in this document

22、 has been revised to reflect the changes made to test methods and requirements given in EN 12201-1, EN 12201-2, EN 12201-3, EN 12201-4 and EN 12201-5. Two new types of pipe have been introduced, i.e. coextruded pipes and peelable layer pipes. The sampling procedures and sampling frequencies for thes

23、e types of pipes have been introduced into the tables for TT, BRT, PVT and AT for pipes.

29、ts and assemblies in accordance with the applicable part(s) of EN 12201 intended to be included in the manufacturers quality plan as part of the quality management system and for the establishment of certification procedures. It is recommended that the quality management system conforms to or is no

30、less stringent than the relevant requirements to EN ISO 9001 1. NOTE 1 If certification is involved, the certification and inspection body is preferably compliant with EN ISO/IEC 17065 5, EN ISO/IEC 17021 3 or EN ISO/IEC 17020 2, as applicable. In conjunction with Parts 1 to 5 of EN 12201 (see Forew

31、ord) this document is applicable to polyethylene (PE) plastics piping systems for water supply, and for drainage and sewerage under pressure. It is applicable to PE pipes, fittings, and valves, their joints and to joints with components of other materials intended to be used under the following cond

32、itions: a) allowable operating pressure, PFA, up to 25 bar1); 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 temperatur

33、e greater than 20 C and up to 40 C, see EN 12201-1:2011, Annex A. 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
