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

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 error. 4.5.4.3 Area variation The accuracy of the thickness measurement will be no better than the accuracy to which the measuring area is known. Area variations due to electrolyte level (excessive agitation), can lead to measurement errors. In some cases it can be advantageous to measure the length after electrolysis is complete and re-calculate the area. 4.5.4.4 Agitation Agitation (i.e. the rate of stirring) shall be sufficient to remove any gas bubbles formed during the test, which can adhere to the test piece or cathode. Excessive agitation shall be avoided to prevent interference with the length of test piece submerged. 4.5.4.5 Condition of the test piece surface Oil, grease, paint, corrosion products, staining or other surface
