This part of ISO 21003 specifies the characteristics of fittings for multilayer piping systems intended to beused for hot and cotd water installations inside buildings for the conveyance of water -- whether or not thewater is intended for human consumption (domestic systems) or for heating systems -- under specifieddesign 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 21003ISO 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 ether parts ofISO 21003This part of ISO 21003 covers fusion, solvent cemented and mechanical fittings for a range of serviceconditions (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 ofISO 21003-1:2008NOTE 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 practics or codesThe polymeric materials used for the stress designed layers are the following: pelybutylene (PS), 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, erosslinked polyethylene (PE-X) as well as adhesives are considered asthermoplastic materials.
