20、e 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. Each member body interested in a subject for which a technical committ
21、ee 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 International Electrotechnical Commission (IEC) on all matters of electrotechn
22、ical 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 Standards adopted by the technical committees are circulated to the member
23、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 subject of patent rights. ISO shall not be held responsible for identifying
24、any or all such patent rights.

28、oride) (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 for human consumption, caused by the products covered by this part of ISO 1452, the
29、 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 these products remain in force. Requirements and test methods for components require
30、ments and test methods are specified in ISO 1452-2, ISO 1452-3 and ISO 1452-4. This part of ISO 1452 establishes the characteristics of fitness for purpose of the plastics piping system composed of pipes, fittings, valves, ancillaries and their joints. Guidance for installation is given in ISO/TR 41
31、911. Guidance for assessment of conformity is provided in ENV 1452-72.

33、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, ISO 1452-3 and ISO 1452-4, it is applicable to joints and assemblies with components of PVC-U, other plastics and non-plastics materia

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
36、 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 temperatures above 45 C on a case-by-case basis. 2 Normative references The following referenced documents are indispensable for the application of this docume
