ISO 22391-5:2007 Plastics piping systems for hot and cold water installations - Polyethylene of raised temperature resistance (PE-RT) - Part 5: Fitness for purpose of the system
This part of ISO 22391 specifies the characteristics of the fitness for purpose of piping systems made from
polyethylene of raised temperature resistance (PE-RT), intended to be used for hot and cold water
installations within buildings for the conveyance of water — whether or not the water is intended for human
consumption (domestic systems) or heating systems — under the design pressures and temperatures
appropriate to the class of application according to ISO 22391-1.
It covers a range of service conditions (classes of application), design pressures and pipe dimension classes,
and also specifies test parameters and test methods. When used in conjunction with the other parts of
ISO 22391, it is respectively applicable to PE-RT pipes, fittings, their joints, and to joints having components
of PE-RT as well as of other plastics and non-plastics materials, used for hot and cold water installations.
It is not applicable for values of design temperature, maximum design temperature or malfunction temperature
in excess of those specified in ISO 22391-1.
NOTE 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.
