EN 13148:2001 (E)IntroductionHot-dip tinned strip is manufactured by passing strip through a molten bath of tin, tin-lead alloy or other tin alloys. By thisprocess a solid bond is created between the metallic coating and the strip by formation of an intermetallic layer.The base metal is hot-dip tinned to protect it against corrosion, to facilitate soldering operations, to improve insertion andwithdrawal forces of connectors, to reduce contact resistance at electrical junctions and to avoid whisker growth oncomponents. The properties of coatings can be modified by mechanical and/or thermal treatments.When the strip is emerging from the bath the thickness of the coating is adjusted by partially wiping off the molten film,either by stationary wiping devices or by a flat air jet. The thickness of the coating can be continuously measured andregulated on both sides of the strip during or after the tinning process. Usually strips are tinned in larger widths and slitto narrower width specified by the customer. In this case, the final slit product has untinned edges.1
ScopeThis European Standard specifies:– the composition and tolerances on dimensions of strip in the thickness range from 0,10 mm up to and including1,50 mm of copper and copper alloys to be tinned, with tin, a tin-lead alloy or other tin alloys;– the composition of material normally used for the melt;– the properties of strip before tinning;–the properties of hot-dip tinned strip;– the preferred thicknesses (mean values) and thickness ranges of coatings;– the edgewise curvature of hot-dip tinned strip;– the sampling procedure;– the methods of test to be used for verification of conformity to the requirements of this standard;– the delivery conditions.2

Requirements6.1
Composition6.1.1
Strip to be tinnedThe composition of the strip shall conform to the requirements for the appropriate material given in Tables 1 and 2.Percentage content of the elements shown as "remainder" (Rem.) is usually calculated by difference from 100 %.6.1.2
Material for the coatingUnless otherwise specified, the composition of the material for the coating shall conform to the requirements for theappropriate material given in Table 3. Other material for the coating shall conform to the requirements agreedbetween the purchaser and the supplier [see 5 i)].6.2
Mechanical properties and grain size of the base materialThe mechanical properties and the grain size, if required, shall conform to the appropriate requirements given inTable 4. The tests shall be carried out in accordance with 8.2 to 8.4.6.3
Dimensions and tolerances6.3.1
Tolerances on thicknessThe thickness of strip before tinning shall conform to the appropriate tolerances given in Table 6. The thickness oftinned strip shall conform to the appropriate combination of tolerances for the thickness of the strip given in Table 6and the thickness range of the coatings ordered, for both faces, given in Table 5.9SIST EN 13148:2004
EN 13148:2001 (E)NOTE
The minimum thickness of the tinned strip is equal to the minimum thickness of the strip before tinning plus the minimumthickness of the coating on each face. The maximum thickness of the tinned strip is equal to the maximum thickness of the stripbefore tinning plus the maximum thickness of the coating on each face.For partially hot-dip tinned strip it can be the case that in the non-coated parts max. 0,03 mm of the base material is removed.6.3.2
Tolerances on widthsGenerally the edges of a supplied strip are not tinned, because a strip is normally tinned in a larger width and slitto the ordered width after hot-dip tinning. In this case the same tolerances as for strip before tinning shall apply asgiven in Table 7. When strip with coated edges is ordered, the tolerance on width shall be agreed between thepurchaser and the supplier.6.4
Edgewise curvature cFor the straightness of the longitudinal edge, which unless otherwise agreed between the purchaser and the suppliershall be based on a measuring length of 1 000 mm, the edgewise curvature c (see Figure 1) shall not exceed thevalues given in Table 8.If the purchaser and the supplier agree on a measuring length of 2 000 mm, the edgewise curvature c shall notexceed the values given in Table 8 multiplied by 4.Keya

Properties of the coating6.5.1
ConditionThe products shall be clean and free from injurious defects which shall be specified by agreement between thepurchaser and the supplier at the time of enquiry and order. A thin film of lubricant or interleaved paper may bepresent to avoid surface damage.6.5.2
AppearanceThe appearance depends on the cooling condition of the liquid film, the coating type and the technique used toremove the excess molten metal. The appearance of the surface may be either bright or dull or a combination ofboth. The appearance of the coating does not affect the suitability of the coating. If there are special requirementsfor appearance of the coating, they shall be agreed between the purchaser and the supplier.6.5.3
SolderabilityIf solderability is required, the acceptance criteria shall be agreed between the purchaser and the supplier. The testshall be carried out in accordance with annex A.10SIST EN 13148:2004
EN 13148:2001 (E)6.5.4
AdhesionIf verification of the coating adhesion is required, the acceptance criteria shall be agreed between the purchaser andthe supplier. The tests shall be carried out in accordance with 8.7.7
Sampling7.1
GeneralWhen required (e.g. if necessary in accordance with specified procedures of a supplier's quality system, or when thepurchaser requests inspection documents with test results, or for use in cases of dispute), an inspection lot shall besampled in accordance with 7.2 and 7.3.7.2
Analysis of the base materialThe sampling rate shall be in accordance with ISO 1811-2. A test sample, depending on the analytical technique tobe employed, shall be prepared from each sampling unit and used for the determination of the composition.NOTE 1
When preparing the test sample, care should be taken to avoid contaminating or overheating the test sample. Carbidetipped tools are recommended; steel tools, if used, should be made of magnetic material to assist in the subsequent removal ofextraneous iron. If the test samples are in finely divided form (e.g. drillings, millings), they should be treated carefully with a strongmagnet to remove any particles of iron introduced during preparation.NOTE 2
In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be followed.NOTE 3 Results may be used from analyses carried out at an earlier stage of manufacturing the product, e.g. at the casting ormaster coil stage, if the material identity is maintained and if the quality system of the manufacturer is certified as conforming toEN lSO 9001 or equivalent.7.3
Tensile, hardness, grain size and technological testsThe sampling rate shall be one test sample per master coil. Sampling units shall be selected from the hot-dip tinnedproducts. The test samples shall be cut from the sampling units. Test samples, and test pieces prepared from them,shall not be subjected to any further treatment, other than any machining operations necessary in the preparationof the test pieces, except in the case of tensile or hardness tests when the coating and any intermetallic layers shallbe removed without deleteriously affecting the base material, e.g. etching is recommended.8
Test methods8.1
Analysis of the base materialAnalysis shall be carried out on the test pieces, or test portions, prepared from the test samples obtained inaccordance with 7.2. Except in cases of dispute, the analytical methods used shall be at the discretion of thesupplier. For expression of results, the rounding rules given in 8.10 shall be used.NOTE
In cases of dispute concerning the results of analysis, the methods of analysis to be used should be in accordance withthe appropriate ISO standards.8.2
Tensile test of the base materialThe tensile properties shall be determined in accordance with EN 10002-1 on the test pieces prepared from the testsamples obtained in accordance with 7.3.8.3
Hardness test of the base materialThe Vickers hardness shall be determined in accordance with EN ISO 6507-1 using a suitable test force selectedfrom those given, on the test pieces prepared from the test samples obtained in accordance with 7.3.11SIST EN 13148:2004
EN 13148:2001 (E)8.4
Estimation of average grain size of the base materialThe average grain size shall be estimated in accordance with EN ISO 2624 on the test pieces prepared from the testsamples obtained in accordance with 7.3.8.5
Edgewise curvature cThe edgewise curvature c shall be measured by appropriate devices.8.6
SolderabilityThe solderability shall be determined as described in annex A.8.7
AdhesionThe adhesion of the coating shall be tested in accordance with EN ISO 7438:2000, 4.2 (bending device with a V-block).8.8
Measurement of coating thicknessThe method of thickness testing is left to the discretion of the supplier.In cases of dispute the X-ray spectrometric method in accordance with ISO 3497 shall be applied, where the totalthickness of the coating (both of the intermetallic phases and of the metallic tin or metallic tin alloy) is measured.Details of test essentials are given in annex B.8.9
RetestsIf there is a failure of one, or more than one, of the tests in 8.1 to 8.5, two test samples from the same inspectionlot shall be permitted to be selected for retesting the failed property (properties). One of these test samples shall betaken from the same sampling unit as that from which the original failed test piece was taken, unless that samplingunit is no longer available, or has been withdrawn by the supplier.If the test pieces from both test samples pass the appropriate test(s), then the inspection lot represented shall bedeemed to conform to the particular requirement(s) of this standard. If a test piece fails a test, the inspection lotrepresented shall be deemed not to conform to this standard.8.10
Rounding of resultsFor the purpose of determining conformity to the limits specified in this standard, an observed or a calculated valueobtained from a test shall be rounded in accordance with the following procedure, which is based upon the guidancegiven in annex B of ISO 31-0 : 1992. It shall be rounded in one step to the same number of figures used to expressthe specified limit in this standard, except that for tensile strength the rounding interval shall be 10 N/mm2 and forelongation the value shall be rounded to the nearest 1 %.The following rules shall be used for rounding:a)if the figure immediately after the last figure to be retained is less than 5, the last figure to be retained shall bekept unchanged;b)if the figure immediately after the last figure to be retained is equal to or greater than 5, the last figure to beretained shall be increased by one.12SIST EN 13148:2004
