28、BS EN 15664-1:2008+A1:2013 EN 15664-1:2008+A1:2013 (E)5 Introduction The main application of metallic materials in water supply is within the domestic installation. The test method given in this standard is designed to provide information on metal release over time from metallic materials into drink

29、ing water. The test is based on a programme of alternating periods of once-through flow and stagnation in a rig, simulating the conditions in a domestic distribution system. The test conditions are more relevant than conditions of continuous through-flow or sit and soak tests and are applicable to a

30、ll metallic materials in distribution systems. Internal corrosion of metallic products in water conveying systems generally leads to the build-up of layers, which might or might not be protective. The factors influencing corrosion are described in EN 12502-1. Type and rate of the production of corro

31、sion products and the rate of metal release can depend on: characteristics of the metallic material; characteristics of the water; design and construction; pressure testing and commissioning; operating conditions and duration of operation. Corrosion product layers begin to form as soon as a metallic

32、 material comes into contact with water. Their properties depend on the factors noted above and for a given water/material combination especially on the operating conditions. It is not possible to reproduce the conditions of an actual installation in tests by constant once-through flow or circulatio

33、n of water. The flow regime (3.16) used in this test simulates the operating conditions in domestic drinking water installations where stagnation times of water considerably exceed the times of through-flow. An assessment by testing is possible only if the influence of the flow regime (3.16) and the

34、 operation period (3.19) is taken into consideration. A compilation of data are needed, which has been determined under defined conditions over a prolonged period of time. In most cases, metal release decreases with operation time. For some alloying elements and impurities, however, an increase in t

35、heir release can be observed.
