AS 4176.1:2010 pdf free download – Multilayer pipes for pressureapplications Part 1: Multilayer piping systems for hotand cold water plumbing applications—General.
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 — 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 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 applies only to multilayer pipes with their inner layer made of plastics.
It covers a range of service conditions (application dasses) and design pressures. It is not applicable for values of design temperature, 7’D’ maximum design temperature, Tm, and malfunction temperature, Tmai, fl excess of those in Table 1.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropnate selections from these aspects, taking into account their particular requirements and any relevant nahonal 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 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 as adhesives are considered as thermoplastic rnatenals
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.
This Appendix sets out additional requirements and variations to ISO 21003-1:2008, appropriate for manufacture and application of the products in Australia. The variations do not negate the requirements of ISO 21003-1:2008.
