18、ucts in aluminium and aluminium alloys for use in contact with food. These requirements cover the chemical composition of the bath, the sealing and the properties of the obtained anodic oxidation coatings. They do not cover dyestuffs and pigments but do cover the metallic deposits produced by electr

26、ion of the supplier confirmed by the purchaser. 4 Ordering information In addition to the information necessary for sufficient definition of the product and its properties as defined by EN 12373-1, order documents shall contain the following information: a) the number of this European Standard; b) a

27、ny requirement on the periodicity of inspection certificates (see Clause 8). 5 Chemical composition of the aluminium or aluminium alloy The chemical composition of the aluminium or aluminium alloys for use in contact with food, intended to be anodised, shall comply with the requirements of EN 601 or

28、 EN 602, as applicable. 6 Chemical composition of the anodization bath The anodization of aluminium or aluminium alloy products intended to be in contact with foodstuff shall be carried out in a diluted aqueous solution of one or more of the following acids: sulfuric acid; sulfomaleic acid; sulfosal

29、icylic acid; oxalic acid; sulfophtalic acid; phosphoric acid. 7 Sealing 7.1 General The anodic oxidation coating shall be sealed unless the coating has been produced in a bath containing only diluted phosphoric acid, or unless the product on which the anodic oxidation coating has been produced will

30、receive another organic or inorganic coating prior to use in contact with food. 7.2 Composition of the sealing bath Sealing shall be done in distilled or demineralized water, which may contain appropriate additives. The inspection certificate shall confirm that the additives and their respective con

31、centrations in the sealing bath comply with current legal requirements. EN 14392:2007 (E) 6 7.3 Technical parameters of the sealing process All the technical parameters of the sealing process, especially the temperature and pH of the bath, the duration of the treatment and the nature and concentrati

32、on of additives shall be chosen to minimise the absorptive power of the anodic oxidation coating and maximise its chemical resistance and to minimizer the migration of potentially hazardous additives. 7.4 Quality assurance and quality assessment The producer shall set up a suitable quality assurance

33、 system in order to monitor the quality of the sealing. The method described in EN 12373-4 and EN 12373-5 shall be used for routine control, and the method described in EN 12373-7 for calibration purpose. NOTE Quality assurance and quality assessment can be done in the framework of a recognised Euro

Box 1507 Tdistrasse 47 CH 8002 Zrich EN 14392:2007 (E) 7 8 Demonstration of conformity with the present standard The anodizing of aluminium and aluminium alloys products for use in contact with food shall be carried out in the

35、 framework of a quality assurance system. This quality assurance system shall allow traceability of a delivered lot to the parameters of the production process that are relevant to the present standard (see Clauses 5 to 7). The manufacturer shall establish an inspection certificate “3.1“ according t

36、o EN 10204 which certifies compliance of the delivered products with the requirements of the present standard. Unless otherwise agreed upon between manufacturer and purchaser, this certificate can be issued at the discretion of the manufacturer either for each delivered lot, or periodically for all

37、products delivered under the present standard within a period of time not exceeding twelve months.

38、. This European Standard does not fall under any Directive of the EU. In the relevant CEN/ CENELEC countries these A-deviations are valid instead of the provisions of the European Standard until they have been removed. Deviation 7.1 (France) The Order of 27th August 1987 concerning aluminium or aluminium alloys materials and objects in contact with foodstuffs, products and food drinks, article 5, enumerates authorized acids put in contact with the above products intended for the French territory.
