20、:2001 BSI 05-2001 1 Scope This part of this European Standard specifies the requirements for the mass other properties and testing of aluminium coatings on steel wire and steel wire products of circular or other cross-section. 2 Normative references This European Standard incorporates by dated or un
21、dated 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 revisions of any of these publications apply to this European Standard only whe
22、n incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

23、ng the mass of aluminium coating on steel products 3 Terms and definitions For the purposes of this European Standard the following terms and definitions apply. 3.1 wire with aluminium coating wire to which an aluminium coating has been applied primarily to protect it against corrosion and/or to imp
24、rove its electrical conductivity. The coating is generally applied by passing the wires individually through a bath of molten aluminium, by extrusion or by cladding 3.2 mass of coating mass of aluminium per unit area is expressed in grams per square meter of stripped wire surface. In the case of thi
25、ck coatings, the quantity of aluminium on the wire may also be expressed by the radial thickness 4 Requirements relating to coating 4.1 Material The ingot of unrefined aluminium used for the coating shall consist of aluminium with less than the following impurities: Copper (Cu)0,10 % max. in mass %
26、Iron (Fe)0,50 % max. in mass % 4.2 Coating mass The minimum mass of aluminium per unit surface area shall comply with the requirements of Table 1. The product standard relating to wire products with an aluminium coating may specify different requirements for minimum mass. Licensed Copy: sheffieldun

The coating on the wire shall b
28、e continuous, reasonably smooth and as evenly distributed as practicable. 4.4 Adherence of the coating The aluminium wire shall be tested in accordance with EN 10244-1. The mandrel for the wrapping test shall have a diameter equal to three times the nominal diameter of the wire tested. 4.5 Special f
29、inishes If the customer requires a special finish it shall be specified at the time of enquiry and order. Similarly if drawing after coating with aluminium is requested it shall be specified at the time of enquiry and order. 5 Tests conditions 5.1 Samples 5.1.1 General See the General requirements i
30、n EN 10244-1. 5.1.2 Length of samples The length of the samples shall be sufficient to allow the various tests to be carried out. 5.2 Determination of mass of coating The mass of the coating shall be determined using the gravimetric method as indicated in EN 10244-1. The stripping solution, sampling
31、, and other procedures, shall be in accordance with ASTM A428. The calculation of the coatings mass is based on the difference in weight in grammes of a test specimen before and after stripping. if m = difference in weight by stripping in grammes; m2 = the weight in grammes of the stripped test samp
