3、entation of EN ISO 21003-2:2008+A1:2011. It was derived from ISO 21003-2:2008,incorporating amendment 1:2011. It supersedes BS EN ISO 21003-2:2008,which is withdrawn.The UK participation in its preparation was entrusted by Technical CommitteePRI/88, Plastics piping systems, to Subcommittee PRI/88/2,
4、 Plastic piping forpressure applications. A list of organizations represented on this committee can be obtained onrequest to its secretary.The UK Committee would like to emphasise that compliance with this BritishStandard does not necessarily mean that products are fit for non-potable hotwater pipes
5、.The requirements contained in this standard are not necessarily indicative ofall the performance requirements, or the suitability of pipework for the serviceconditions likely to be encountered in a particular pipework application in theUK. In particular: This standard does not replace BS 7291 parts
6、 1, 2 and 3 (Class S) whichcontain detailed requirements for performance and contact with drinkingwater for pipes, fittings and joints manufactured from Polybutylene and PEXmaterials. (i) The normal maximum operating cold water supply pressure in theUK is 12.5 bar, a pressure that some application c
7、lasses of pipe inthis standard do not meet. (ii) This standard does not specifically describe push-fit joints that arethe predominant jointing method in the UK but defines mechanicalfittings in general. (iii) There is a disparity between the malfunction temperature (100 C)quoted in Table 1 of Part 1
8、 of this standard and the malfunctiontemperatures applicable to boilers (110 C) conforming to BS EN 297:1994, BS EN 483:2000 and BS EN 625:1996. Current UKpractice can be found in BS 7291-1 which should be consulted whenapplying this standard. Pipe systems not conforming to BS 7291-1could be subject
9、ed to temperatures in service for which they have notbeen tested. (iv) The unique and traditional practice in the UK is to use productscertified to BS 7291 Class S for all applications, as defined in BS 7291-1. This is recognized in the National Annex to BS EN 12828that requires the use of systems s
10、uitable for the maximumtemperatures and pressures for their intended application specifiedin BS 7291-1.

36、rdization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right t
37、o be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Sta
38、ndards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an In
39、ternational Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

42、 EN ISO 21003-2:2008+A1:2011EN ISO 21003-2:2008+A1:2011 (E)vIntroduction The system standard of which this is Part 2 specifies the requirements for a multilayer piping system. The multilayer piping system is intended to be used for hot and cold water installations inside buildings. In respect of pot
43、entially adverse effects on the quality of water intended for human consumption caused by the products covered by ISO 21003: no information is provided as to whether the products may be used without restriction in any of the member states of the EU or EFTA; it should be noted that, while awaiting th
44、e adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. Requirements and test methods for material and components other than pipes are specified in ISO 21003-1 and ISO 21003-3. Characteristics relating
45、 to fitness for purpose (mainly for joints) are covered in ISO 21003-5. ISO/TS 21003-7 gives guidance on the assessment of conformity. This part of ISO 21003 specifies the characteristics of pipes. Other system standards which, at the date of publication of this part of ISO 21003, had been published
46、 for plastics piping systems used for the same application are listed in Annex A.

47、ics of pipes for multilayer piping systems intended to be used for hot and cold water installations inside buildings for the conveyance of water whether or not the water is intended for human consumption (domestic systems) or heating systems under specified design pressures and temperatures appropri
48、ate to the class of application (see Table 1 of ISO 21003-1:2008). It also specifies the test parameters for the test methods referred to in this part of ISO 21003. ISO 21003 is a reference product standard. It is applicable to multilayer pipes, fittings, their joints, and also to joints with compon
49、ents made of other plastics and non-plastics materials intended to be used for hot and cold water installations. This part of ISO 21003 is intended for use only in conjunction with all the other parts of ISO 21003. ISO 21003 covers a range of service conditions (application classes) and design pressures. It is not applicable for values of design temperature, TD, maximum design temperature, Tmax, and malfunction temperature, Tmal, in excess of those in Table 1 of ISO 21003-1:2008.
