適用范圍：This part of ISO 21003 specifies the characteristics of pipes for multilayer piping systems intended to be usedfor hot and cold water installations inside buildings for the conveyance of water — whether or not the water isintended for human consumption (domestic systems) or heating systems — under specified design pressuresand 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, their joints, and also tojoints with components made of other plastics and non-plastics materials intended to be used for hot and coldwater installations. This part of ISO 21003 is intended for use only in conjunction with all the other parts ofISO 21003.ISO 21003 covers a range of service conditions (application classes) and design pressures. It is not applicablefor 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 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), polyethyleneof raised temperature resistance (PE-RT), crosslinked polyethylene (PE-X), polypropylene (PP) andchlorinated poly(vinyl chloride) (PVC-C).The PE-X used shall be fully crosslinked and shall comply with the requirements of the relevant referenceproduct standard (ISO 15875).NOTE 2 For the purposes of ISO 21003, crosslinked polyethylene (PE-X) as well as adhesives are considered asthermoplastic materials.Solid-wall pipes with thin outer layers (applied as protection layers or barrier layers, for instance) are notcovered 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.
