EN 13603:2013 (E) 4 1 Scope This European Standard specifies methods for assessing the tin coating on drawn round copper wire for the manufacture of electrical conductors, e.g. according to EN 13602. This European Standard includes test methods for the determination of the following characteristics: a) thickness of the unalloyed tin coating; b) continuity of the tin coating; c) adherence of the tin coating. WARNING — This European Standard can involve the use of hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with their use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 610, Tin and tin alloys — Ingot tin 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 unalloyed tin coating layer of pure tin on the surface of tinned wire 3.2 alloyed tin coating diffusion layer of copper and tin formed at the copper wire and tin coating interface during tinning and subsequent drawing and annealing processes 3.3 total tin coating sum of the thicknesses of the unalloyed tin coating and the alloyed tin coating 3.4 measuring area area of the surface over which a single measurement is made 4 Thickness of the unalloyed tin coating 4.1 Principle Anodic dissolution of a well-defined area of the unalloyed coating using a suitable electrolyte, followed by detection of the virtually complete dissolution of the unalloyed coating by a rapid change in cell voltage. SIST EN 13603:2013
EN 13603:2013 (E) 5 Calculation of the unalloyed coating thickness from the quantity of electricity (in coulombs) used, which can in turn be calculated from: a) the time interval between the start of the test and the first rapid change of cell voltage, if it is conducted at constant current density; or b) the integrated quantity of electricity used in dissolving the unalloyed coating. 4.2 Reagents and materials 4.2.1 Electrolyte, either a hydrochloric acid electrolyte or an electrolyte recommended by the instrument manufacturer. For the hydrochloric acid electrolyte, dilute 170 ml of hydrochloric acid (HCl), ρ = 1,18 g/ml, to 1 000 ml with deionised water. NOTE The unalloyed tin coating dissolves anodically at an efficiency of nearly 100 %; for determination of the electrolyte efficiency, see 4.5.6. WARNING — Hydrochloric acid causes burns and is irritating to the respiratory system. Avoid breathing the vapour and prevent contact with eyes and skin. This electrolyte dissolves tin coatings at very low cell voltages at which there is no anodic attack on the substrates when they are exposed at the end of the test. 4.2.2 Tin, tin grade in accordance with EN 610. 4.3 Apparatus Suitable instruments may be constructed from readily available components. Alternatively, a proprietary instrument may be used. 4.3.1 Direct reading instruments Proprietary direct reading instruments are available for use with electrolytes recommended by the manufacturer. The calculation of thickness of tin coating from current density is made electronically. The instrument shall have some means of indicating when the unalloyed tin coating has been fully removed. 4.3.2 Other instruments Instruments other than proprietary direct reading instruments record the quantity of electricity, in coulombs, used in dissolving the unalloyed coating from the measuring area, usually in arbitrary units, from which the thickness can be calculated using factors or tables. 4.3.3 Electrolytic cell The electrolytic cell consists of a container for the electrolyte, a cathode and an anode, which is the test sample. If the container is made of metal, such as stainless steel, the container can serve as the cathode. If the container is made of insulating material, a separate cathode is required. Also required are a device for supporting the appropriate length of the test sample and an agitation mechanism. Depending on the wire diameter, the test sample may be a straight length of wire or, if necessary to obtain sufficient surface area for smaller diameter wires, a holding device such as that shown schematically in Figure 1 is required. A magnetic stirrer or similar system shall be used to provide agitation. SIST EN 13603:2013

If necessary, clean the test surface with a suitable organic solvent (see 4.5.4.5). Care should be taken to avoid removal of metal during the cleaning operation. 4.5 Procedure for determining the thickness of unalloyed tin coatings 4.5.1 General If commercial equipment is used, follow the manufacturer's instructions with respect to the operating procedure for measurement, the electrolyte and, if necessary, calibration. Appropriate attention shall be given to the factors listed in 4.5.4. The performance of the instrument shall be checked using a reference specimen of pure tin wire. A tin grade in accordance with EN 610 shall be used. The test shall be carried out in accordance with 4.5.6. If the instrument readings or the calculation of K give an electrolytic efficiency of equal to or greater than 98 %, the instrument may be used without further adjustment. Otherwise, the cause of discrepancy shall be remedied. Proprietary instruments shall be calibrated in accordance with the manufacturer's instructions. SIST EN 13603:2013
EN 13603:2013 (E) 7 4.5.2 Determination of measuring area For the determination of the measuring area, the length L of the test piece in millimetres shall be determined with an accuracy of 1 % and the diameter d of the test piece for wires with a nominal diameter of < 0,6 mm shall be determined with an accuracy of 1 % and for wires with a nominal diameter of ≥ 0,6 mm with an accuracy of 0,5 %. The measuring area A in square centimetres is given by the Formula (1): 100π
L
d = A×× (1) NOTE An exact area of stripping is necessary for accuracy and the main source of error is due to the meniscus and current field at the electrolyte surface. 4.5.3 Electrolysis (Dissolution of the unalloyed tin coating) The electrolyte (4.2.1) and test piece shall be introduced into the cell so that a known area is exposed to the electrolyte. Efforts shall be made to ensure that no gas bubbles occur on the measuring area by use of the agitation mechanism. The electrical connections shall be made and the agitator operated. Electrolysis shall be continued until dissolution of the unalloyed tin coating is complete, as indicated by a sharp change in the anode potential or cell voltage, or by the operation of the automatic cut-out. After completion of the test, the test piece shall be removed from the cell, rinsed with water and examined to ensure that complete removal of the unalloyed tin coating has occurred over the measuring area (see 4.5.4.9). 4.5.4 Factors affecting the measuring accuracy 4.5.4.1 Coating thickness The optimum accuracy is achieved with coating thicknesses in the range 0,2 m up to 50 m. 4.5.4.2 Current variation For instruments using the constant current and time measuring technique, current variation will cause errors. For instruments using a current-time integrator, too large a change in current can change the anode current efficiency or interfere with the end-point, causing an er
