21、ndard, the following definitions apply : 3.1 ingot : Cast product intended for remelting. 3.2 jumbo : Large ingot, not suitable for manual handling, weighing at least 30 kg. Normally a jumbo weighs several hundred kilograms. 3.3 example by banding, for the purposes of handling, shipment and storage.
22、 bundle : Collection of ingots taken from one or more batches (see 3.6) and secured, for 3.4 zinc alloys : Zinc with additions of one or more alloying elements, such as : Al, Mg, Cu, Cr, Ti. NOTE : Zinc alloys are normally supplied in ingot form, but may be available in liquid form. COPYRIGHT DIN DE

24、r identified quantity of liquid metal, taken from a single cast. 4 Alloy designation 4.1 General Zinc alloys conforming to this standard are designated either by symbol (see 4.2) or by number (see 4.3). For marking and labelling purposes only (see clause 9) the short designation and/or colour code m
25、ay be used (see 4.4 and 4.5). NOTE : Informative annex A gives the relationship between the former national alloy designations and those designations used in this standard. 4.2 Designation of zinc alloys by symbol The designation by symbol is derived from the designation system given in IS0 301 :198
26、1. EXAMPLE : ZnAI4Cul designates a zinc alloy containing, nominally, 4 % aluminium and 1 ?LO copper 4.3 Designation of zinc alloys by number The designation by number shall consist of two letters ZL (denoting zinc alloy) and four numerals, having the following significance : - the first two numerals
27、 indicate the nominal aluminium content ; - the third numeral indicates the nominal copper content ; and - the fourth numeral indicates the nominal content of the next highest alloying element. If this is less than 1 YO , the fourth numeral shall be “O“. 4.4 Colour code The alloy colour code shall c
28、onsist of two colours. The colours shall be as given in table 1, in relation to the alloy symbols or alloy numbers. COPYRIGHT DIN DEUTSCHES Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 5 EN 1774 : 1997 4.5 Short designation The short designation of the alloy shall
29、consist of the two letters ZL, followed by one or two numerals. The short designations shall be as indicated in table 1, in relation to the alloy symbol or alloy number. NOTE : For a transitional period of five years from the date of publication of this standard, the short designation, when used as
30、an ingot mark (see 9.1), may be composed in a different form from that given in 4.5, provided that the numerals specified in the short designation in table 1 are used. 5 Manufacture The zinc alloy shall be manufactured from : a) zinc ingots or liquid zinc conforming to grade Z1 of EN 1179, with the
31、addition of appropriate alloying elements (see table 1) ; and/or b) identifiable casting process returns, e.g. sprues, runners and overflows ; and/or c) identifiable castings rejected from the foundry, or after secondary operations. Used, recycled materials and all other materials, which could cause
32、 contamination, such as shredder scrap shall not be used. 6 Ordering information In order to facilitate the enquiry, order and confirmation of order procedures between the supplier and the purchaser, the purchaser shall state on the enquiry and order the following information : a) the number of this
33、 European Standard (EN 1774) ; b) the designation of the zinc alloy required, by either symbol or number (see 4.2 et 4.3) ; c) the total mass required, and whether ingot or liquid form is required ; d) whether a specific ingot shape is required (see 7.2) ; e) whether a certificate of chemical compos
34、ition or a declaration of conformity is required (see clause IO). COPYRIGHT DIN DEUTSCHES Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 6 EN 1774 : 1997 7 Requirements 7.1 Chemical composition The ingots or liquid shall conform to the requirements for chemical compo
35、sition given for the appropriate alloy in table 1. NOTE : Methods of analysis, for use in cases of dispute, are given in prEN 12019. In expressing the results for the analysis, the values obtained shall be rounded in one step to the same number of figures used to expressed the specified limit in tab
36、le I. The following rules shall be used for rounding : a) if the figure immediately after the last figure to be retained is less than five, the last figure to be retained shall be kept unchanged ; b) if the figure immediately after the last figure to be retained is equal to or greater than five, the
37、 last figure to be retained shall be increased by one. 7.2 Shape of ingots The shape of ingots shall be at the discretion of the supplier, unless a specific shape is agreed between the purchaser and the supplier at the time of ordering (see 6 d). 7.3 Surface condition of ingots The surface condition
38、 of the ingots shall be such that it does not affect the chemical composition and is not detrimental to the use of the ingots. 8 Sampling Sampling of zinc alloy ingots and liquid, for verification of compliance with the chemical composition requirements shall be in accordance with prEN 12060. 9 Mark
39、ing and labelling 9.1 Ingot Each ingot shall be marked with the following minimum information : a) name or identification of manufacturer ; b) the zinc alloy designation, by alloy symbol and/or number, and/or colour code, and/or short designation (see clause 4 et table 1).
