    30、on 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 drinking water. The test is based on a programme of alternating periods

    31、 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 all metallic materials in distribution systems. Internal corrosion

    32、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 corrosion products and the rate of metal release can depend on: charact

    33、eristics 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 material comes into contact with water. Their properties depend o

    34、n 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 circulation of water. The flow regime (3.16) used in this test simulates the

    35、 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 operation period (3.19) is taken into consideration. A compilatio

    36、n 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 their release can be observed. DIN EN 15664-1:2014-03 EN 15664-1:20
