28、003-5:2008 has been approved by CEN as a EN ISO 21003-5:2008 without any modification. Introduction The system standard of which this is Part 5 specifies the requirements for a multilayer piping system. The multilayer piping system is intended to be used for hot and cold water installations inside b
29、uildings. In respect of potential 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 note
30、d that, while awaiting the 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 components of the piping system are specified in ISO 21003-1, ISO 21003-2 and ISO 2100
31、3-3. ISO/TS 21003-7 gives guidance on the assessment of conformity. This part of ISO 21003 specifies the characteristics for fitness for purpose. For ancillary equipment, separate standards can apply. Guidance on installation of plastics piping systems made from various materials intended to be used
32、 for hot and cold water installations is given in ENV 12108. 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 21003-5:2008-11 EN ISO 21003-5:2008 (E) 1
33、Scope This part of ISO 21003 specifies the characteristics for the fitness for purpose of 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 f
34、or heating systems under specified design pressures and temperatures appropriate to the class of application (see Table 1 of ISO 21003:2008). 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
35、to multilayer 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. ISO 21003
36、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. NOTE 1 It is the responsibility of the p
37、urchaser 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 stress-designed layers are the following: polybutylene (PB),
38、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 relevant reference product standard (ISO 15875). NOTE 2 For
39、the purposes of this 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.
