Normenausschuss Wasserwesen (NAW, Water Practice Standards Committee) 2010-11-01 3 DIN SPEC 19674-1:2011-02 Introduction This DIN SPEC is the result of the work of a group of experts consis
13、ting of experienced representatives of the plastics industry. The DIN SPEC is intended to be a step on the way to further standardization in an area not yet covered by any DIN standard. The individual user is responsible for verifying whether the DIN SPEC is suitable for his purpose and whether the
14、current level of knowledge is taken into account. DIN SPEC 19674 specifies the requirements for a piping system and its components made from glass fibre reinforced polyethylene (PE-GF). The piping system is intended to be used for water supply, including the conveyance of raw water prior to treatmen
15、t, for drainage and sewerage under pressure, vacuum sewerage systems, and for systems for the conveyance of water for general purposes. With respect to the possible effects of products in accordance with DIN SPEC 19674 on the quality of water for human consumption (potable water), the following shal
16、l be considered: a) this specification does not indicate whether the products may be used without restrictions; b) products intended for use in water supply systems shall conform to national regulations and to test requirements which ensure the fitness for purpose regarding the contact with water fo
17、r human consumption. For pipes, the requirements and test methods of DIN SPEC 19674-2 apply. 1 Scope This part of DIN SPEC 19674 specifies the general requirements for pressure piping systems (main and connecting pipes) made from glass fibre reinforced polyethylene (PE-GF) intended for the conveyanc
18、e of water for human consumption, including raw water prior to treatment, for drainage and sewerage under pressure, vacuum sewerage systems, and for systems for the conveyance of water for general purposes. NOTE 1 In this specification, DN refers to the inside diameter of pipes and fittings. It also
19、 specifies the test parameters for the test methods referred to in this specification. In conjunction with the other parts of DIN SPEC 19674, it applies to pipes and fittings from PE-GF, their joints with each other and to components from other materials intended for use under the following conditio
20、ns: a) a maximum allowable operating pressure (MOP) up to and including 22 bar; b) an operating temperature of 20 C as the reference temperature. NOTE 2 DIN SPEC 19674 includes specifications for maximum allowable operating pressures and specifies requirements for the colour of components and the us
21、e of additives. It is the responsibility of the purchaser or specifier to make the appropriate selection from these criteria while taking into account their own particular requirements as well as any relevant national guidelines or regulations and installation practices or codes. NOTE 3 For applicat
22、ions at constant operating temperatures higher than 20 C and up to 40 C, see Annex A. 4 DIN SPEC 19674-1:2011-02 2 Normative references The following referenced documents are indispensable for the application of this document.
