26、2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisi
27、ons of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 573-3, Aluminium and aluminium alloys Chemical composition and form of wrought products Part 3:
28、 Chemical composition. 3 Definitions For the purposes of this standard the following definitions apply. 3.1 aluminium metal with a minimum content of 99,0 % by mass of aluminium, provided that the content by mass of any other element does not exceed the limit specified in Table 1 Table 1 Aluminium o
29、ther elements 3.2 aluminium alloy metallic substance in which aluminium predominates by mass over each of the other elements, provided that: a) the content by mass of at least one of the other elements, or iron plus silicon taken together, is greater than the limits specified in Table 1; or, b) the
30、total content by mass of such other elements exceeds 1,0 %. 3.3 wrought product product obtained by hot and/or cold working processes such as extruding, forging, hot rolling, cold rolling or drawing, either exclusively or in combination. Examples for wrought products are rod/bar, wire, tube, profile
31、, sheet, strip, forging 4 Maximum permissible content of elements for foodstuff application 4.1 Wrought aluminium The content by mass of the other elements which are present in wrought aluminium shall not exceed the following limits: iron + silicon k 1,0 %; chromium, magnesium, manganese, nickel, zi
32、nc, titanium, tin k 0,10 % each; copper k 0,2 %. Copper is permitted in a proportion greater than 0,10 % but not more than 0,20 % and provided that neither the chromium nor manganese content exceeds 0,05 %; other elements k 0,05 % each. 4.2 Wrought aluminium alloys The content by mass of the element
33、s which are added to form wrought aluminium alloys or which are present as impurities, shall not exceed the maximum values given in Table 2.

37、ium alloys which shall be used for the fabrication of articles for use in contact with food are those which conform with the requirements in 4.1 or 4.2 as applicable. For every use of a standardized wrought aluminium or aluminium alloy for the fabrication of articles for use in contact with food, th
38、e conformity with this European Standard shall be established by checking the maximum contents specified in EN 573-3 against the requirements in 4.1 or 4.2 as applicable. NOTEIt is strongly recommended to use standardized aluminium or aluminium alloys. The selection of the aluminium or aluminium all
39、oy for a given application shall be the responsibility of the end product manufacturer, depending on the intended final use.
