This Eur

25、opean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2015, and conflicting national standards shall be withdrawn at the latest by January 2015. Attention is drawn to the possibility that some of the el

26、ements 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 supersedes EN 12873-1:2003. The major revisions of EN 12873-1:2003 are: the inclusion of procedures for testing glassy (porcelain

27、/vitreous enamel) materials. This inclusion enabled an improvement of the title of the standard; the test temperatures, outlined in Clause 4 Principle, are more specific; the use of chromic acid is removed because of safety concerns; the examples of extended collection and analysis of migration wate

28、rs (Annex C) are more systematic. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav

29、Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

30、ion In respect of potential adverse effects on the quality of water intended for human consumption caused by the materials, it is called to mind that, while awaiting the adoption of verifiable European acceptance criteria, the relevant national regulations remain in force. This European Standard has

31、 been drawn up with the objective to describe a test method to determine the migration of substances from products made from, or incorporating, organic and glassy (porcelain/vitreous enamel) material for use in contact with water intended for human consumption. Annex A, which is normative, describes

32、 an alternative arrangement for flushing pipes having a nominal size greater than DN 80. Annex B, which is informative, describes additional procedures for testing non-homogeneous products and pipes having a nominal size greater than DN 80. Annex C, which is informative, describes a schedule for the

33、 preparation of migration waters. Annex D, which is informative, describes procedural tests using standard additions (positive controls). Annex E, which is informative, describes the migration test procedure in a schematic manner. Annex F, which is informative, provides information on a Cell system

34、for testing glassy materials. This European Standard will result in one of a series of standards on test methods which support the appropriate standards. This standard, Part 1, is the first in a series of standards for dealing with the influence of migration from materials on water intended for huma

35、n consumption, including: Part 1: Test method for factory-made products made from or incorporating organic and glassy (porcelain/vitreous enamel) materials; Part 2: Test method for non-metallic and non-cementitious site-applied products; Part 3: Test method for ion exchange and absorbent resins; Par

36、t 4: Test method for membrane water treatment systems. DIN EN 12873-1:2014-09EN 12873-1:2014 (E) 6 1 Scope This European Standard specifies a procedure to determine the migration of substances from factory-made or factory-applied products for use in contact with water intended for human consumption.

37、 Materials used to make such products include plastics, rubber and glassy (porcelain/vitreous enamel) materials. This European Standard is applicable to products intended to be used under various conditions for the transport and storage of water intended for human consumption, including raw water us

38、ed for the production of water intended for human consumption. It covers the extraction by water of substances from the finished products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
