34、ort of fluids”. EN ISO 1452-4:2009 (E) DIN EN ISO 1452-4:2010-04 Introduction The System Standard, of which this is Part 4, 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 suppl
35、y 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. a) This part of ISO 1452 provides no informatio
36、n 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 material and components, other than valves, are specified in ISO 1452-1, ISO 1452-2 and
37、 ISO 1452-3. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 1452-5. This part of ISO 1452 covers the characteristics of valves. Guidance for installation is given in ISO/TR 41911. Guidance for assessment of conformity is provided in ENV 1452-72. For the convenience of
38、 users of this part of ISO 1452, marking on valves according to withdrawn International Standards (e.g. ISO 4422-4:1997) may be considered valid for a period, e.g. up to three years from the date of publication of this part of ISO 1452. 4 EN ISO 1452-4:2009 (E) DIN EN ISO 1452-4:2010-04 1 Scope This
39、 part of ISO 1452 specifies the characteristics of valves made from unplasticized poly(vinyl chloride) (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
40、this part of ISO 1452. In conjunction with ISO 1452-1, ISO 1452-2, ISO 1452-3 and ISO 1452-5 it is applicable to PVC-U valves 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 ground; b) conveyance of wate
41、r above ground for both outside and inside buildings; c) buried and above-ground drainage and sewerage under pressure. It is applicable to valves 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 pur
42、poses as well as for waste water under pressure. This part of ISO 1452 is also applicable to valves 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 1 The producer and the end-user can come to ag
43、reement on the possibilities of use for temperatures above 45 C on a case-by-case basis. This part of ISO 1452 is applicable to valves of the following types: valves for solvent cementing; valves for elastomeric ring seal joints; valves for flanged joints. NOTE 2 It is the responsibility of the purc
44、haser 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. 5 EN ISO 1452-4:2009 (E) DIN EN ISO 1452-4:2010-04 2 Normative references The following referenced do
