This document shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2008 and conflicting national standards shall be withdrawn at the latest by May 2008. Within its programme of work, Techn
15、ical Committee CEN/TC 132 has entrusted CEN/TC 132/WG 9 to prepare the following standard: EN 14392, Aluminium and aluminium alloys Requirements for anodised products for use in contact with foodstuff. Attention is drawn to the possibility that some of the elements of this document may be the subjec

19、SIEN 14392:2007 (E) 4 1 Scope This European Standard specifies requirements for coloured or uncoloured anodic oxidation coatings on wrought and cast products in aluminium and aluminium alloys for use in contact with food. These requirements cover the chemical composition of the bath, the sealing and
20、 the properties of the obtained anodic oxidation coatings. They do not cover dyestuffs and pigments but do cover the metallic deposits produced by electrolytic colouring. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、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) any requirement on the periodicity of inspection
29、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 EN 602, as applicable. 6 Chemical composition o
30、f 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; sulfosalicylic acid; oxalic acid; sulfophtalic acid; pho
31、sphoric 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 receive another organic or inorganic coating pri
32、or 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 concentrations in the sealing bath comply with curr
33、ent legal requirements. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 13/05/2008 08:18, Uncontrolled Copy, (c) BSIEN 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 durat
34、ion of the treatment and the nature and concentration 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
35、 producer shall set up a suitable quality assurance 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 assessmen

37、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 framework of a quality assurance system. This quality assurance system shall allow traceability of a delivered lot to the parameters of the productio

The manufacturer shall establish an inspection certificate “3.1“ according to EN 10204 which certifies compliance of the delivered products with the requirements of the present standard. Unless otherwise agreed upon between ma
39、nufacturer and purchaser, this certificate can be issued at the discretion of the manufacturer either for each delivered lot, or periodically for all products delivered under the present standard within a period of time not exceeding twelve months.
