26、N ISO 22391-1:2009ISO 22391-1:2009(E) iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technic

27、al committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wi

28、th the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Inte

29、rnational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document ma

30、y be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

34、duction The System Standard, of which this is Part 1, specifies the requirements for a piping system and its components when made from polyethylene of raised temperature resistance (PE-RT). The piping system is intended to be used for hot and cold water installations. In respect of potential adverse

35、 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 provides no information as to whether the products can be used without restriction. b) Existing national regulations concerning the use a

36、nd/or characteristics of the products remain in force. This part of ISO 22391 specifies the general aspects of the plastics piping system.

41、 to the class of application. This part of ISO 22391 covers a range 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, fi

42、ttings, their joints and to joints having components of PE-RT, 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 th

43、ose it specifies. 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. 2 Normative references The following refer
