This standard specifies the characteristics of pipes made from crosslinked polyethylene (PE-X) for piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems), and for heating systems, under design pressures and temperatures appropriate to the class of application (see Table 1 of KS M ISO 15875-1).
This standard covers a range of service conditions (application classes), design pressures and pipe dimension classes.
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. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with KS M ISO 15875-1, KS M ISO 15875-3 it is applicable to PE-X pipes, their joints and to joints with components of PE-X, other plastics and non-plastics materials intended to be used for hot and cold water installations. It is applicable to pipes with or without (a) barrier layer(s).
NOTE 2 In the case of plastics pipes provided with a thin barrier layer, e.g. to prevent or greatly diminish the diffusion of gases and the transmission of light into or through the pipe wall, the design stress requirements are totally met by the base polymer (PE-X). 1.2 Annex C(Normative) shall be effective with the body of this standard until Dec 31, 2006, but it shall be deleted after that.
