18、:2009ISO 1452-1:2009(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 technical committees.
19、 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 with the Interna
20、tional 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 International Stan
21、dards 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 may be the subje
22、ct of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1452-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 155, Plastics piping systems and ducting systems, in collaboration with ISO Technical Committee
23、 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 first edition cancels and replaces ISO 4422-1:1996,
24、which has 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(vinyl chloride) (PVC-U): Part 1: General Part 2: Pipes Part 3: Fittin

26、erved vIntroduction The System Standard, of which this is Part 1, 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 un
27、der pressure. 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 or not the products can be used without re
28、striction. b) Existing national regulations concerning the use and/or the characteristics of these products remain in force. Requirements and test methods for components are specified in ISO 1452-2, ISO 1452-3 and ISO 1452-4. Characteristics for fitness for purpose (mainly for joints) are establishe
29、d in ISO 1452-5. This part of ISO 1452 specifies the general aspects of PVC-U. Guidance for installation is given in ISO/TR 41911. Guidance for assessment of conformity is provided in ENV 1452-72.

31、age under pressure Unplasticized poly(vinyl chloride) (PVC-U) Part 1: General 1 Scope This part of ISO 1452 specifies the general aspects of unplasticized poly(vinyl chloride) (PVC-U) solid-wall piping systems intended for water supply and for buried and above-ground drainage and sewerage under pres
32、sure. In conjunction with ISO 1452-2, ISO 1452-3, ISO 1452-4 and ISO 1452-5, it is applicable to PVC-U pipes, fittings, valves and ancillary equipment, their joints and to joints with components of other plastics and non-plastics materials intended to be used for the following: a) water mains and se
33、rvices 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 is applicable to piping systems intended for the supply of water under pressure up to and including 25 C (cold water), intended
34、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 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 T
35、he 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
