20、eration of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that comm

21、ittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accorda

22、nce with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires

23、 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 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22391-3 was prepared by Technical

24、 Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies. This second edition cancels and replaces the first edition (ISO 22391-3:2007), which is extended from only dealing with PE-RT material (referred

25、to as Type I) to cover PE-RT materials Type I and Type II. ISO 22391 consists of the following parts1), under the general title Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance (PE-RT): Part 1: General Part 2: Pipes Part 3: Fittings Part 5: F

26、itness for purpose of the system 1) This System Standard does not incorporate a Part 4: Ancillary equipment or a Part 6: Guidance for installation. For ancillary equipment, separate standards can apply. Guidance for installation of plastics piping systems made from different materials, intended to b

27、e used for hot and cold water installations, is covered by ENV 12108. BS EN ISO 22391-3:2009ISO 22391-3:2009(E) ISO 2009 All rights reserved vIntroduction The System Standard, of which this is Part 3, specifies the requirements for a piping system and its components when made from polyethylene of ra

28、ised temperature 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

29、ISO 22391 provides 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

30、 publication of 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 pipin

33、characteristics of fittings for 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 and cold water installations within buildings for the conveyance of water, whether or

34、not the water is intended for human consumption (domestic systems) and for heating systems, under the design pressures and temperatures appropriate to the class of application according to ISO 22391-1. This part of ISO 22391 covers a range of service conditions (classes of application), design press

35、ures and pipe dimension classes, and also specifies test parameters and test methods. In conjunction with the other parts of ISO 22391, it is applicable to fittings made of PE-RT, as well as to those made of other materials, intended to be fitted to pipes conforming to ISO 22391-2 for hot and cold w

36、ater installations, the joints of which are in accordance with ISO 22391-5. This part of ISO 22391 is applicable to the following types of fitting: mechanical fittings; socket fusion fitting; electrofusion fittings; fittings with incorporated inserts. It is not applicable to values of design tempera

37、ture, 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 regu
