24、 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 committee. Int

25、ernational 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 accordance with t

26、he 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 approval

27、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 1452-3 was prepared by the European Committ

32、vIntroduction The System Standard, of which this is Part 3, specifies the requirements for a piping system and its components made from unplasticized poly(vinyl chloride) (PVC-U). The piping system is intended to be used for water supply and for buried and above-ground drainage and sewerage under pr

33、essure. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the products covered by this part of ISO 1452, the following are relevant. a) This part of ISO 1452 provides no information as to whether the products may be used without restriction. b)

34、 Existing national regulations concerning the use and/or the characteristics of these products remain in force. Requirements and test methods for material and components, other than fittings, are specified in ISO 1452-1, ISO 1452-2 and ISO 1452-4. Characteristics for fitness for purpose (mainly for

35、joints) are established in ISO 1452-5. This part of ISO 1452 specifies the characteristics of fittings. Guidance for installation is given in ISO/TR 41911. Guidance for the assessment of conformity is provided in ENV 1452-72. For the convenience of users of this part of ISO 1452, marking on fittings

36、 and flanges according to withdrawn International Standards (e.g. ISO 4422-3:1996) may be considered valid for a period, e.g. up to three years from the date of publication of this part of ISO 1452.

38、cs of fittings made from unplasticized poly(vinyl chloride) (PVC-U) for piping systems intended for water supply and for buried and above-ground drainage and sewerage under pressure. It also specifies the test parameters for the test methods referred to in this part of ISO 1452. In conjunction with

39、ISO 1452-1, ISO 1452-2 and ISO 1452-5, it is applicable to PVC-U fittings and to joints with components of PVC-U, other plastics and non-plastics materials intended to be used for the following: a) water mains and services buried in the ground; b) conveyance of water above ground for both outside an

40、d inside buildings; c) buried and above-ground drainage and sewerage under pressure. It is applicable to fittings in piping systems intended for the supply of water under pressure up to and including 25 C (cold water), intended for human consumption and for general purposes as well as for waste wate

41、r under pressure. This part of ISO 1452 is also applicable to components for the conveyance of water and waste water up to and including 45 C. For temperatures between 25 C and 45 C, Figure A.1 of ISO 1452-2:2009 applies. NOTE 1 The producer and the end-user can come to agreement on the possibilitie

42、s of use for temperatures above 45 C on a case-by-case basis. Depending on the jointing method, this part of ISO 1452 is applicable to the following types of fittings: fittings for solvent cementing; elastomeric ring seal fittings. PVC-U fittings can be manufactured by injection-moulding and/or be f

43、abricated from pipe. This part of ISO 1452 is also applicable to PVC-U flange adapters and to the corresponding flanges made from various materials. This part of ISO 1452 covers a range of fitting sizes and pressure classes and gives requirements concerning colours. NOTE 2 It is the responsibility o

44、f 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.
