ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Int
19、ernational 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 Standards adopted by the technical committees are circulated to the member bodies for voting. Public

The pipin
25、g 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 for human consumption, caused by the products covered by this part of ISO 1452, the following are relevant.
26、a) This part of ISO 1452 provides no information as to whether or not the products can be used without restriction. 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
27、-2, ISO 1452-3 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 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

29、rt 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 pressure. In conjunction with ISO 1452-2, ISO 1452-3, ISO 1452-4 and ISO 1452-5, it is applicable
30、 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 services buried in the ground; b) conveyance of water above ground for both outside and inside
31、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 for human consumption and for general purposes as well as for waste water under pressure. Thi
32、s 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 The producer and the end-user can come to agreement on the possibilities of use for temperatur
33、es above 45 C on a case-by-case basis. 2 Normative references The following referenced documents are indispensable for the application of this document.
