DIN SPEC 19674-1

Abstract

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 conveyance 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. <br>NOTE 1 In this specification, DN refers to the inside diameter of pipes and fittings. <br>It also specifies the test parameters for the test methods referred to in this specification. <br>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 conditions: <br>a) a maximum allowable operating pressure (MOP) up to and including 22 bar; <br>b) an operating temperature of 20 &#176;C as the reference temperature. <br>NOTE 2 DIN SPEC 19674 includes specifications for maximum allowable operating pressures and specifies requirements for the colour of components and the use 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. <br>NOTE 3 For applications at constant operating temperatures higher than 20 &#176;C and up to 40 &#176;C, see Annex A.
