The standard has been prepared under the mandate given to CEN by the Commission of the European Communities and the European Free Trade Area deleted text. With respect to

25、potential adverse effects on the quality of water intended for human consumption caused by metallic materials, attention is drawn to the fact that the relevant national regulations remain in force until the adoption of verifiable European acceptance criteria. Water intended for human consumption is

26、hereafter referred to as “drinking water” and means the same as the definition given at Article 2(1) of the Council Directive 98/83/EC on the quality of water intended for human consumption. This European Standard has been drafted in accordance with the CEN Internal Regulations, Part 3. This Europea

27、n Standard is Part 1 of a series dealing with the test method to determine the release of metals from metallic products into drinking water comprising: Part 1: Design and operation; ! Part 2: Test waters.“ Part 1 describes a test method to produce contact waters for the assessment of metal release f

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

The test can be used for three purposes: a) assess a material as a reference material fo
