This document shall be given the status of a national standard,
13、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of an identical text or by endorsement, at the latest by May 2008 and conflicting national standards shall be withdrawn at the latest by May 2008.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, Technical Committee CEN/TC 132 has entrusted CEN/TC 132/WG 9 to prepare the following standard: EN 14
14、392, 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 subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rig
15、hts. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses on standardised standard products under reasonable and not discriminatory conditions, then this product shall be removed from the corresponding standard. According to the CEN/CENELEC Internal Regulati
16、ons, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherla

EN 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
18、 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 electrolytic colouring. 2 Normative references T

27、ction 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 composi
28、tion 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; sulfosalicylic acid; oxalic acid; sulfophtalic aci
29、d; 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 receive another organic or inorganic coati
30、ng 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 concentrations in the sealing bath comply wit
31、h 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 concentration of additives shall be chosen to minimis
32、e 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 system in order to monitor the quality of
33、 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 European quality label such as QUALANOD1). 1)Q

35、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 to EN 10204 which certifies compliance of t
