39、 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 information is provided as to wh
40、ether 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 products remain in force. Requi
41、rements and test methods for material and components other than pipes are specified in ISO 21003-1 and ISO 21003-3. Characteristics relating 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 sp
42、ecifies the characteristics of pipes. 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. DIN EN ISO 21003-2:2011-07 EN ISO 21003-2:2008 + A1:2011 (E) 51 Scope This par
43、t of ISO 21003 specifies the characteristics 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 d
44、esign 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 multilayer pipes, fittings, the
45、ir 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 covers a range of service conditio
46、ns (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 purchaser or specifier to make the
47、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), polyethylene of raised temperature
48、 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 the purposes of ISO 21003, crossli
49、nked polyethylene (PE-X) as well as adhesives are considered as thermoplastic materials. Solid-wall pipes with thin outer layers (applied as protection layers or barrier layers, for instance) are not covered by ISO 21003 but are specified in the Amendments to ISO 15874-2, ISO 15875-2 and ISO 15876-2. The total thickness of such outer layers, including the thickness of the adhesives used, shall be 0,4 mm. 2 Normative references The following referenced documents are indispensable for
