35、 ISO 1452-3:2010-04 3 piping systems and ducting systems”, the secretariat of which is held by NEN, in collaboration with Technical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids”. Introduction The System Standard, of which this is Part 3, specifies the require
36、ments 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 pressure. In respect of potential adverse effects on the quality of water intended
37、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) Existing national regulations concerning the use and/or the characteristics of t
38、hese 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 joints) are established in ISO 1452-5. This part of ISO 1452 specifies the charac
39、teristics 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 For the convenience of users of this part of ISO 1452, marking on fittings and flanges according to withdrawn International Standards (e.g. ISO 4422-3:1996
40、) may be considered valid for a period, e.g. up to three years from the date of publication of this part of ISO 1452. EN ISO 1452-3:2009 (E) DIN EN ISO 1452-3:2010-04 4 1 Scope This part of ISO 1452 specifies the characteristics of fittings made from unplasticized poly(vinyl chloride) (PVC-U) for pi
41、ping 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 ISO 1452-1, ISO 1452-2 and ISO 1452-5, it is applicable to PVC-U fittings
42、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 and inside buildings; c) buried and above-ground drainage and sewerage under
43、 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 water under pressure. This part of ISO 1452 is also applicable to components f
44、or 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 possibilities of use for temperatures above 45 C on a case-by-case basis. Depending on
45、 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 fabricated from pipe. This part of ISO 1452 is also applicable to PVC-U fla
46、nge 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 of the purchaser or specifier to make the appropriate selections from these
47、 aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
