4、.The requirements contained in this standard are not necessarily indicative of all the performance requirements, or the suitability of pipework for the service conditions, likely to be encountered in a particular pipework application in the UK. In particular: (i) The normal maximum operating cold wa
5、ter supply pressure in the UK is 12. bar, a pressure that some application classes of pipe in this standard do not meet.(ii) This standard does not specifically describe push-fit joints that are the predominant jointing method in UK but defines mechanical fittings in general.(iii) There is a dispari
6、ty between the malfunction temperature R100 C/ quoted in Table 1 of Part 1 of this standard and the malfunction temperatures applicable to boilers R110 C/ conforming to BS EN 297:199D, BS EN D83:2000 and BS EN 62:1996. Current UK practice can be found in BS 7291-1 which should be consulted when appl
7、ying this standard. Pipe systems not conforming to BS 7291-1 could be sub-jected to temperatures in service for which they have not been tested. (iv) The unique and traditional practice in the UK is to use products certified to BS 7291 Class S for all applications, as defined in BS 7291-1. This is r
8、ecognized in the National Annex to BS EN 12828 that requires the use of systems suitable for the maximum temperatures and pressures for their intended application specified in BS 7291-1.This standard does not replace BS 7291 parts 1, 2 and 3 (Class S) which contain detailed requirements for performa

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. ISO 22391-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water su

This second edition cancels and replaces the first edition (ISO 22391-1:2007), which is extended from only dealing with PE-RT material (referred to as Type I) to cover PE-RT materials Type I and Type II.

33、 For ancillary equipment, separate standards can apply. Guidance for installation of plastics piping systems made from different materials, intended to be used for hot and cold water installations, is covered by ENV 12108.

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.

39、for hot and cold water installations Polyethylene of raised temperature resistance (PE-RT) Part 1: General 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 temperat
40、ure resistance (PE-RT), Type II, 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) and for heating systems, under specified design pressures and temperatures appropriate
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
