32、1:2008-11 Introduction The system standard of which this is Part 1 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 potentially adverse effects on the quality of water i
33、ntended 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 the adoption of verifiable European criteria, existi
34、ng 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 21003-2 and ISO 21003-3. Characteristics relating to fitness for purpose (mainly for joints) are covered in
35、ISO 21003-5. ISO/TS 21003-7 gives guidance on the assessment of conformity. This part of ISO 21003 specifies the general aspects of multilayer piping systems. For ancillary equipment, separate standards can apply. Guidance on installation of plastics piping systems made from various materials intend
36、ed to be used 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 EN ISO 21003-1:2008 (E) DIN EN ISO 21003
37、-1:2008-11 1 Scope This part of ISO 21003 specifies the general aspects 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 heating systems
38、under specified design pressures and temperatures appropriate to the class of application (see Table 1). ISO 21003 is a reference product standard (see 3.4.3). It is applicable to multilayer pipes, fittings, their joints, and also to joints with components made of other plastics and non-plastics mat
39、erials 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 applies only to multilayer pipes with their inner layer made of plastics. It covers a range of service conditions (applicat
40、ion 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. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from thes
41、e 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 resistance (PE-RT), crosslinked
42、 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, crosslinked polyethylene (PE-X) as well
43、 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 ou
44、ter layers, including the thickness of the adhesives used, shall be u 0,4 mm. 5 EN ISO 21003-1:2008 (E) DIN EN ISO 21003-1:2008-11 2 Normative references The following referenced documents are indispensable for the application of this document.
