Plastics piping systems for hot and cold water installations -- Polyethylene of raised temperature resistance (PE-RT) -- Part 5: Fitness for purpose of the system
Это стандарт пересмотрен ISO 22391-5:2009
ISO 22391-5:2007 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.
