The work of preparing International Standards is nor

20、mally 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in

21、the work. ISO collaborates closely with 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 prepar

22、e 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 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that som

23、e 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 1452-2 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 155, Plastics piping systems and ducting sys

24、tems, in collaboration with ISO Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This f

25、irst edition cancels and replaces ISO 4422-2:1996 and ISO 2045, which have been technically revised. ISO 1452 consists of the following parts, under the general title Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure Unplasticized poly(viny

27、ndard, of which this is Part 2, 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 pressure. In respect of potent

28、ial 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 or not the products can be used without restriction. b) Existing national re

29、gulations concerning the use and/or the characteristics of these products remain in force. Requirements and test methods for material and components, other than pipes, are specified in ISO 1452-1, ISO 1452-3 and ISO 1452-4. Characteristics for fitness for purpose (mainly for joints) are established

30、in ISO 1452-5. This part of ISO 1452 specifies the characteristics of pipes. Guidance for installation is given in ISO/TR 41911. Guidance for assessment of conformity is provided in ENV 1452-72.

31、eserved 1Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure Unplasticized poly(vinyl chloride) (PVC-U) Part 2: Pipes 1 Scope This part of ISO 1452 specifies the characteristics of solid-wall pipes made from unplasticized poly(vinyl chloride)

32、 (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 ISO 1452-1 and ISO 1452-5, it is applicable to extruded PVC

33、-U pipes without a socket and pipes with a socket (integral or not), 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 pressure. It

34、 is applicable to 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 specifies pipes for the conveyance of water and waste water

35、up to and including 45 C. For temperatures between 25 C and 45 C, Figure A.1 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. This part of ISO 1452 specifies a range of pipe sizes and pressure classes

36、, and gives requirements concerning colours. NOTE 2 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 r
