21、uropean standard specifies the requirements for the mass, other properties and testing of non-ferrous metal coatings on steel wire and steel wire products of circular or other cross- section. This European standard deals with requirements of general application and is of use for those coatings for w
22、hich no particular requirements have been laid down in the following parts (2 to 6). Deviations are possible, particularly if required for well-defined products. In such cases, appropriate requirements shall be part of the relevant product standard. 2 Normative reference This European Standard incor
23、porates 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 revisions of any of these publications apply to this Euro
24、pean Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

25、 Part 1: Test methods 3 Term and definition For the purposes of this European standard the following term and definition apply. 3.1 wire with non-ferrous metallic coating wire to which a non-ferrous metallic coating has been applied. Depending on the metal, the coating may be obtained by dipping in
26、a bath of molten metal, by conversion using a bath of metallic salts in solution, by extrusion, by cladding, by electroplating using an electrolytic solution or by other methods 4 Requirements relating to coating 4.1 Requirements for the specific type of metal and alloy The type, quality and grade o
27、f coating metal or alloy shall be stated at the time of enquiry and order. 4.2 Coating mass The coating mass shall be explicitly specified, preferably by reference to the appropriate product standard. If not the appropriate part of this standard shall apply. Licensed Copy: sheffieldun sheffieldun, n
28、a, Thu Oct 26 04:13:16 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 5 EN 10244-1:2001 The mass of the coating shall preferably be expressed as being the mass of coating per unit of surface area of bare wire (g/m2). Other expressions may be accepted, such as the quantity of coating per unit of wei
29、ght of coated wire or the thickness of coating. This last is generally expressed as being the minimum required thickness. NOTEThe thickness of the coating may be converted into an equivalent mass per unit of bare wire surface or vice versa on the basis of the specific mass of the coating material (s
30、ee Table 1). A coating of 1 micrometer (1m) gives a diameter of 2 micrometer (2m) greater.

31、ing The coating shall be reasonably smooth, as evenly distributed as industrially practicable and not show discontinuities such as bare patches, dross contamination, etc. 4.4 Special finishes If the purchaser requires a special finish e.g. wax-coating; agreed upon at the time of enquiry and order or
32、 sets out additional requirements for the coating, these special details shall be agreed at the time of enquiry and order. The inspection methods shall be defined at the same time. 4.5 Adherence of coating The adherence wrapping test shall be carried out in accordance with EN 10218-1 and the coating
33、 shall adhere to the steel below the coating. It shall not crack or split to such an extent that slivers of coating can be removed by simply rubbing with the fingers. The flaking or removal during testing of small particles resulting from mechanical polishing of the coating surface or by contact wit
34、h the forming equipment shall not be considered to be a cause for rejection. The wrapping test shall be carried out on wire with a nominal diameter of 7,5 mm or less. Unless otherwise specified, the relationship between the diameter of the coiling mandrel and the diameter of the wire shall be in acc
35、ordance with 5.3.

36、ndrel. 5 Test conditions 5.1 Selection of samples 5.1.1The number and the basis for the selection of test pieces shall be defined in the product specification. In the absence of such a standard, the manufacturer and purchaser shall agree between them on the degree of sampling. 5.1.2When taking the s
37、amples, care shall be taken to avoid damaging the surface. Parts of the wire which are visibly damaged shall not be used. 5.1.3 A test piece of a suitable length for the specified tests shall be taken from one or both ends of each coil selected for sampling. 5.2 Determination of mass of coating 5.2.
38、1 Gravimetric method 5.2.1.1 General The mass of coating shall be determined using a gravimetric method. The metallic coating on a surface of known area is dissolved in a suitable solution to remove the coating completely without attacking the surface of the steel wire. If necessary a suitable inhib
39、itor is added to the solution. The resulting mass loss is determined by weighing the test piece before and after the coating has dissolved. 5.2.1.2 Procedure If necessary the test piece shall be degreased using an organic solvent which does not attack the coating and the test piece shall then be dri
40、ed. Before stripping, the test piece shall be weighed with high accuracy i.e. better than 1 % of the assumed mass of the coating. The test piece shall be immersed fully in the stripping solution at ambient temperature and left until the coating dissolves completely. A sufficient quantity of solution
41、 shall be used to limit any changes in the composition of the stripping solution. After stripping, the test piece shall be rinsed under running water and, if necessary, brushed to remove any loose substances which may be adhering to the surface; it shall then be plunged into alcohol or any other app
42、ropriate solvent, rapidly dried and once again weighed to the accuracy stipulated above. The surface area of the exposed surface shall then be determined to an accuracy of 1 % by measuring the dimensions of the test piece.

44、ssed in grams A : The coated surface of the sample in mm2 I : The length of the sample in mm d : The diameter of the chemically stripped wire (in case of round wire) in mm m : Weight loss of the sample by the chemical stripping mA : The mass of coating in g/m2 The mass of coating on the samples is:
45、m = m1-m2 The mass of coating per unit surface area = 2 g/mm A m? expressed in g/m2 - this becomes : 2 6 A g/m A 10? ? m m (1) For round wire the surface area can be expressed as : A = ? ? d ? l(2) 3 2 2 1085 , 7 l 4 ? ? d m = (? ? d ? l) d ? 1,962 ? 10- 3 (3) Combining (2) and (3) results in: g1096

47、) 5.2.2 Other methods Depending on the type of coating, other methods may be used to obtain the mass of the coating more simply and more quickly. The use of these methods is authorized under the following conditions: proof of the validity of the method shall be supplied and in the event of any dispu
48、te, only the gravimetric method shall apply. 5.3 Adherence test If the wire diameter is less than or equal to 7,5 mm, the adherence of the coating shall be tested by wrapping the wire for at least six tight turns around a cylindrical mandrel. Wires of diameter greater than 7,5 mm shall undergo a ben
49、ding test at an angle of at least 90 around the mandrel. Unless otherwise specified in the subsequent parts of this standard or in the product standard the relationship between the diameter of the mandrel and the diameter of the wire shall be in accordance with Table 2. Table 2 Diameter of mandrel for wrapping test Diameter of wire dDiameter of mandrel 4mm4d 4mm5d 5.4 Retests Testing and retesting shall be in accordance with EN 10021.
