27、e resistance (PE-RT). The piping system is intended to be used for hot and cold water installations. In respect of potential adverse effects on the quality of water intended for human consumption caused by the products covered by ISO 22391, the following are relevant. a) This part of ISO 22391 provi

28、des no information as to whether the products can be used without restriction. b) Existing national regulations concerning the use and/or characteristics of the products remain in force. This part of ISO 22391 specifies the general aspects of the plastics piping system. At the date of publication of

29、 this part of ISO 22391, System Standards Series for piping systems of other plastics materials used for the same application are the following: ISO 15874 (all parts), Plastics piping systems for hot and cold water installations Polypropylene (PP) ISO 15875 (all parts), Plastics piping systems for h

31、O 22391-1:2010-04 EN ISO 22391-1:2009 (E) 4 1 Scope This part of ISO 22391 specifies the general characteristics of piping systems made of polyethylene of raised temperature resistance (PE-RT), Type I, and polyethylene of raised temperature resistance (PE-RT), Type II, intended to be used for hot an

32、d cold water installations within buildings for the conveyance of water, whether or not the water is intended for human consumption (domestic systems) and for heating systems, under specified design pressures and temperatures appropriate to the class of application. This part of ISO 22391 covers a r

33、ange of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and defines terms. In conjunction with the other parts of ISO 22391, it is applicable to PE-RT pipes, fittings, their joints and to joints having components of PE-RT,

34、as well as of other plastics and non-plastics materials, respectively, used for hot and cold water installations. It is not applicable to values of design temperature, maximum design temperature or malfunction temperature in excess of those it specifies. NOTE It is the responsibility of the purchase

35、r 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. 2 Normative references The following referenced documents are indispensable for the application of this d
