Other measuring methods agreed upon by both supply and demand sides can also be used. 5.7 Continuity of coating The continuity of coating of tin-coated copper-clad steel wire shall be tested in accordance with the provisions of Procedure a) in 5.5 of GB/T 4909.9-2009. The test piece shall be subjected to two immersion cycles. 5.8 Adherence of coating The adherence of coating of tin-coated copper-clad steel wire shall be tested in accordance with the provisions of GB/T 4909.11-2009. The test piece shall be wound on a test rod which does not exceed 4 times the nominal diameter of the wire. The test piece after being wound is subjected to one-cycle immersion test. 5.9 Solderability The normal solderability of tin-coated copper-clad steel wire shall be tested in accordance with the provisions of GB/T 2423.32-2008 and the following detailed rules. a) Test piece preparation. On each coil (shaft) of sample drawn in the specified number, CUT off 2 test pieces with a length of about 30 mm. The test piece shall not be touched by hand or contaminated, and before the test, shall not be cleaned. b) Test conditions. The solder is Sn96.5Ag3.0Cu0.5. The soldering flux is prepared with 25% of rosin and 75% of ethyl alcohol. The test temperature is (245±3)°C. c) Test parameters. The immersing depth is 3 mm. The immersing speed is 20 mm/s. The immersing duration is 5 s. d) Test result. On the automatically-recorded wetting curve, TAKE the than 3 coils (shafts). When the batch is large, it shall not be more than 10 coils (shafts). The test piece shall be cut off from each sample unit (coil or shaft). 6.4 Determination rules If all inspections are qualified, the inspection batch shall be qualified. When there is an unqualified item, it shall take double the number of samples for the second inspection of the unqualified item; if there is still nonconformity, the batch of products shall be judged as unqualified.7 Packaging, product marking, transport, and storage7.1 Packaging Tin-coated copper-clad steel wire shall be evenly and neatly wound around the wire coil (shaft). The wire end shall be firmly fixed. Proper distance shall be maintained between the outermost wire turn and the edge of side plate of wire coil. Each coil (shaft) of wire shall be wrapped with Kraft paper and then packaged in a plastic bag containing desiccant, and then loaded into a barrel (box) lined with moisture-proof paper. 7.2 Product marking Each coil (shaft) of tin-coated copper-clad steel wire products shall be accompanied by a label, which indicates. a) Name of manufacturing enterprise (with bar code attached); b) Type and specification; c) Gross weight and net weight (kg); d) Production date (year and month, or batch number); e) This Standard’s number. 7.3 Transport The product, during transport, shall be protected from wet oxidation and corrosion. 7.4 Storage The product shall be stored in a dry, ventilated, non-corrosive media and hazardous gas warehouse. The storage time shall not exceed half a year. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
