36、 pipes, fittings and valves for the transport of fluids”. DIN EN ISO 1452-2:2010-04 EN ISO 1452-2:2009 (E) 3 Introduction The System Standard, 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 s
37、ystem 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. a)
38、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 material and components, other than pip
39、es, are specified in ISO 1452-1, 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 characteristics of pipes. Guidance for installation is given in ISO/TR 41911. Guidance for assessment of conformi
40、ty is provided in ENV 1452-72. DIN EN ISO 1452-2:2010-04 EN ISO 1452-2:2009 (E) 4 1 Scope This part of ISO 1452 specifies the characteristics of solid-wall pipes made from unplasticized poly(vinyl chloride) (PVC-U) for piping systems intended for water supply and for buried and above-ground drainage
41、 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-U pipes without a socket and pipes with a socket (integral or not), intended to be used for t
42、he 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 is applicable to piping systems intended for the supply of water under pressure up to and inc
43、luding 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 up to and including 45 C. For temperatures between 25 C and 45 C, Figure A.1 applies. NOTE 1 T
44、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. This part of ISO 1452 specifies a range of pipe sizes and pressure classes, and gives requirements concerning colours. NOTE 2 It is the responsibility of the purchaser
45、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 references The following referenced documents are indispensable for the application of this doc
