15、ECISS/TC 30, Steel wires, the Secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2001, and conflicting national standards shall be withdrawn at the late
16、st by September 2001. This European Standard for non-ferrous metallic coating on steel wire is made up of the following parts: Part 1: General principles Part 2: Zinc and zinc alloy coatings Part 3: Aluminium coatings Part 4: Tin coatings Part 5: Nickel coatings Part 6: Copper, bronze and brass coat

18、, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 4 EN 10244-3:2001 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-sec
19、tion. 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
20、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 publication referred to applies (including amendments). EN 10244-1, Steel wire and wire products Non-ferrous metallic coating
21、s on steel wire Part 1: General principles ASTM A428, Test method for determining 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 c
22、oating has been applied primarily to protect it against corrosion and/or to improve 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 e
23、xpressed in grams per square meter of stripped wire surface. In the case of thick 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 alumi
24、nium with less than the following impurities: Copper (Cu) 0,10 % max. in mass % 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
25、 may specify different requirements for minimum mass.Page 5 EN 10244-3:2001 BSI 05-2001 4.3 Appearance of coating The aluminium coated wire shall be free of slivers, scale and other imperfections not consistent with good commercial practice. The coating on the wire shall be continuous, reasonably sm
26、ooth 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 finishes If the customer req
27、uires 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 in EN 10244-1. 5.1.2 Length
28、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, and other procedures, sha
29、ll 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; m 2= the weight in grammes of the stripped test sample; d = the diameter of the
30、 (round) wire in mm; m A= the mass of coating in g/m 2 ; 2 1 962 = A m m d mPage 6 EN 10244-3:2001 BSI 05-2001 Table 1 Requirements for the mass of aluminium coating Diameter of wire (mm) d Coating mass Class A amin.
