EN ISO 21003-3:2008 (E) DIN EN ISO 21003-3:2008-11 Introduction The system standard of which this is Part 3 specifies the re

32、quirements 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 potentially adverse effects on the quality of water intended for human consumption caused by the products covered by ISO 21003: no infor

33、mation 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 the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these prod

34、ucts remain in force. Requirements and test methods for materials and components other than fittings are specified in ISO 21003-1 and ISO 21003-2. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 21003-5. ISO/TS 21003-7 gives guidance on the assessment of conformity. Th

35、is part of ISO 21003 specifies the characteristics of fittings. Other system standards which, at the date of publication of this part of ISO 21003, had been published for plastics piping systems used for the same application are listed in Annex A. 4 DIN EN ISO 21003-3:2008-11 EN ISO 21003-3:2008 (E)

36、 1 Scope This part of ISO 21003 specifies the characteristics of fittings 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 for heating s

37、ystems under specified design pressures and temperatures appropriate 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 multila

38、yer pipes, fittings, their joints, and also to joints with components 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. This part of ISO 210

39、03 covers fusion, solvent-cemented and mechanical fittings for 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 IS

40、O 21003-1:2008. NOTE 1 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 regulations and installation practices or codes. The polymeric materials used for the stres

41、s-designed layers are the following: polybutylene (PB), polyethylene of raised temperature resistance (PE-RT), crosslinked polyethylene (PE-X), polypropylene (PP) and chlorinated poly(vinyl chloride) (PVC-C). The PE-X used shall be fully crosslinked and shall comply with the requirements of the rele

42、vant reference product standard (ISO 15875). NOTE 2 For the purposes of ISO 21003, crosslinked polyethylene (PE-X) as well as adhesives are considered as thermoplastic materials. 2 Normative references The following referenced documents are indispensable for the application of this document.
