This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2010, and conflicting national standards shall be withdrawn at the latest by August 2010. Attent

15、ion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document is one of a series of test methods which support associated product standards.

16、 This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). In respect of potential adverse effects on the quality of water intended for human consumption caused by metallic

17、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 hereafter referred to as “drinking water“ and means the same as the definition given at Article 2(1)

18、 of the Council Directive 98/83/EC on the quality of water intended for human consumption 1. This document has been drafted in accordance with the CEN Internal Regulations, Part 3.

DIN EN 15664-2 EN 15664-2:2010 (E) 4 Introduction The test method given in Part 1 of E

22、N 15664 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 of once-through flow and stagnation in a rig simulating the conditions in a domestic distribution system. The test can be used fo

23、r three purposes as follows: a) to assess a material as a reference material for a category of materials using the results of several investigations in different waters covering a broad range of water compositions; b) to assess a material for approval by way of comparative testing; c) to obtain data

24、 on the interaction of local water with a material. This part of EN 15664 specifies test water(s) when the test procedure is used for the purposes a) to c) above. To assess a new category of materials it is required to test the candidate reference material in several waters. This set of waters repre

25、sents a parameter set of conditions which might be realistically observed in the field as extreme conditions. The test waters defined in this part of EN 15664 are based on an overview on drinking water qualities in Europe and consider the present knowledge on the dependence of metal release on water

26、 qualities. To add a new material to a category, a comparative test against the reference material is required with specific test water. These test waters are defined in this document. DIN EN 15664-2 EN 15664-2:2010 (E) 5 1 Scope This European Standard defines the requirements for test waters used i

27、n the dynamic test rig defined in EN 15664-1. This document specifies test water(s) when the test procedure is used to: a) assess a material for approval as a reference material for a category of materials; b) assess a material for approval by way of comparative testing; c) obtain data on the intera

28、ction of local water with a material. NOTE Local waters used for test waters are not treated with corrosion inhibitors. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated

29、references, the latest edition of the referenced document (including any amendments) applies.

31、and definitions given in EN ISO 8044:1999, EN 12502-1:2004 and EN 15664-1:2008 apply. 4 Test rig The test rig shall be constructed and operated according to EN 15664-1. 5 Test water 5.1 Principles for the selection of test waters For the selection of test waters all the following principles apply: p

32、arameters of the test waters are within the requirements of the Council Directive 98/83/EC 1; test waters shall be local waters and shall not be treated with corrosion inhibitors (except for 5.4); test waters shall represent realistic worst case waters for the purpose of the test. The test water sha

33、ll be selected depending on the purpose of the test, see 5.2, 5.3 and 5.4. DIN EN 15664-2 EN 15664-2:2010 (E) 6 5.2 Test water for reference materials Three test waters shall be used to collect data for the assessment of a new category of metallic material. These are: very hard neutral, soft acidic

34、and soft alkaline. For these waters, annual mean values are given in Table 1. Table 1 Test water characteristics for testing reference materials Characteristics pH Alkalinity mmol/l Sum of Cl- and SO42- mmol/l Oxygen TOC mg/l Test water 1 Very hard neutral water 7,1 to 7,5 5,0 3 70 % saturation 1,5

35、Test water 2 Soft water weakly acidic 6,7 to 7,1 0,5 to 1,3 - 70 % saturation Test water 3 Soft water alkaline 8,0 to 8,4 0,7 to 1,3 - 70 % saturation TOC shall not be increased by adding organic substances to the test water. 5.3 Test water for comparative testing For comparative testing a local dri

36、nking water shall be used, provided that the water is suitably corrosive. This means that metal release rate(s) of the element(s) under consideration shall be high enough to result in metal concentrations for a valid comparison to be made. NOTE It is recommended that the metal release behaviour of t

37、he reference material in the proposed test water is available. 5.4 Test water for interaction of a local water with a material When the test procedure is used to obtain data on the interaction of local water with a material, the test water shall be the local water representative of the particular supply zone under consideration. In this case, the water may contain corrosion inhibitors.
