This European Standard shall be given the status of a national standard, either by
14、publication of an identical text or by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latest by November 2002. This document will supersede EN 1179:1995. This is one of a series of European Standards for zinc and zinc alloy products. Other p
15、roducts are specified in the following standards: EN 988, Zinc and zinc alloys Specifications for rolled flat products for building. EN 1774, Zinc and zinc alloys Alloys for foundry purposes Ingot and liquid. EN 12844, Zinc and zinc alloys Castings Specification. EN 13283, Zinc and zinc alloys Secon
16、dary zinc. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun- tries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Ma
17、lta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. EN 1179:2003 (E) 4 1 Scope This European Standard specifies the classification, chemical composition, marking and other requirements for primary zinc. The grades of zinc included in the standard are thos
18、e which are traded internationally. The standard does not include requirements for secondary zinc produced by remelting. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropria
19、te places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions 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 publicati
20、on referred to applies (including amendments). EN 12060, Zinc and zinc alloys Method of sampling Specifications. EN 12441-3, Zinc and zinc alloys - Chemical analysis - Part 3: Determination of lead, cadmium and copper - Flame atomic absorption spectrometric method EN 12441-5, Zinc and zinc alloys -

22、Standard, the following terms and definitions apply: 3.1 ingot cast product intended for remelting 3.2 primary zinc zinc obtained from the ore, or other zinc-bearing material, by a process of distillation or by chemical or electrolytic reduction NOTEPrimary zinc is normally supplied in ingot form, b
23、ut may also be available in liquid form. 3.3 cast 3.3.1 cast, for non-continuous casting product of one furnace, or crucible melt 3.3.2 cast, for continuous casting identified volume of liquid metal 3.4 batch number of ingots taken from a single cast EN 1179:2003 (E) 5 3.5 bundle collection of ingot
24、s taken from a single cast and secured, for example by banding, for the purposes of handling, shipment and storage 3.6 jumbo large ingot not suitable for manual handling, weighing at least 30 kg. Normally a jumbo weighs several hundred kilogram 4 Manufacture Zinc ingots shall be manufactured by cast
25、ing from liquid primary zinc. 5 Ordering information The following information shall be supplied by the purchaser in the order to assist the supplier in providing the cor- rect material: a) the number of this European Standard (EN 1179); b) the grade of the primary zinc required (see Table 1); c) th
26、e total mass required; d) for ingots, their individual nominal mass; e) when a specific ingot shape is required (see 6.2); f) when a certificate of analysis or a declaration of conformity is required (see clause 9). 6 Requirements 6.1 Chemical composition The primary zinc shall conform to the chemic
27、al composition given for the appropriate grade in Table 1. In expressing the results for the analysis, the values obtained shall be rounded to the same number of decimal places as used in expressing the specified limit in Table 1. The following rules shall be used for rounding: a) if the figure foll
28、owing the last figure to be retained is less than 5, the last figure to be retained shall be kept un- changed; b) if the figure following the last figure to be retained is equal to or greater than 5, the last figure to be retained shall be increased by one unit. 6.2 Shape of ingots The shape of ingo
29、ts shall be at the suppliers discretion unless a specific shape has been agreed upon between purchaser and supplier and stated in the enquiry and order see clause 5 e). 6.3 Surface condition of ingots The surface condition of ingots shall be such that it does not affect the chemical composition requ
30、irements, and is not detrimental to the end use of the ingots. EN 1179:2003 (E) 6 7 Sampling and analysis The sampling of primary zinc for verification of its conformity to the chemical composition requirements of this stan- dard shall be in accordance with EN 12060. The chemical composition given i
31、n Table 1 shall, in case of dispute, be determined by wet chemical methods given in EN 12441-3, EN 12441-5, and EN 12441-6, unless otherwise agreed. NOTE: Optical emission spectrometry analysis, according to EN 12019, is recommended only for production control purposes and end-product certification.
32、 8 Marking and labelling All ingots or bundles shall be marked, or labelled, with the following minimum information: a) the producers mark; b) the zinc grade (by grade classification or by colour code see Table 1; c) the batch or cast reference; d) the mass of the ingot or bundle. 9 Inspection docum
33、ents If requested by the purchaser at the time of ordering, the supplier shall furnish inspection documents with each consignment. The documentation shall be as chosen by the purchaser see clause 5 f) and shall be in accordance with either a) or b), as follows: a) a certificate of analysis, giving t
