21、pply”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by January 2015, and conflicting national standards shall be withdrawn at the latest by January 2015.

22、 Attention 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 supersedes EN 12873-1:2003. The major revisions of EN 12873-1:2003 are:

23、 the inclusion of procedures for testing glassy (porcelain/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 exam

24、ples of extended collection and analysis of migration waters (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, C

BS EN 12873-1:2014EN 12873-1:2014 (E) 5 Introduction 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 r

27、egulations remain in force. This European Standard has 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 hum

28、an consumption. Annex A, which is normative, describes 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

29、 C, which is informative, describes a schedule for the 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

30、is informative, provides information on a Cell system 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

31、of migration from materials on water intended for human 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:

32、Test method for ion exchange and absorbent resins; Part 4: Test method for membrane water treatment systems. BS EN 12873-1:2014EN 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

33、contact with water intended for human consumption. 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 inte

34、nded for human consumption, including raw water used 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 documen

46、porcelain, vitreous enamel coating (as defined in EN 15826) that is in contact with water and applied to a variety of products that produce or store water at elevated temperature 4 Principle Each test piece is subjected to a specified pre-treatment procedure of stagnation and prewashing. The surface

47、 of the test piece that is exposed in practice to water intended for human consumption, is brought into contact with test water during at least three sequential migration periods. A migration period is either: 72 h at (23 2) C for products intended to come into contact with cold water; 24 h at a spe

48、cified temperature at (60 2) C (warm water test) and/or (85 2) C (hot water test) for products intended to come into contact with warm or hot water. Migration rates for the first three migration periods are determined by analysis of the required substances in the corresponding migration waters. Refe

49、rring product standards and/or national regulatory authorities may specify the number of sequential migration periods to be carried out. NOTE 1 The test is carried out under conditions to ensure that calculation of a reliable migration rate is facilitated. These conditions are not meant to simulate real use conditions. Relating the results obtained from this standard to real use conditions is carried out using a conversion procedure. This procedure will be specified in product standards or national regulations.
