5.2.2 Test tab
5.2.2.1 Test tabs for the insertion-withdrawal test described in Clause 6.4 shall be made of unplated brass, identified as CDA C26000 Alloy with a hardness of 62 ±7 on the Rockwell 30T scale.
5.2.2.2 Test tabs for the temperature and current cycling tests described in Clause 6.5 shall be made of tin-plated steel or corrosion resistant steel having a hardness of 68 ±5 on the Rockwell 30T scale.
5.2.2.3 In regard to Clause 5.2.2.2, for connectors intended exclusively for use with production tabs of copper alloy, an unplated brass test tab of C26000 Alloy with a hardness of 62 ±7 on the Rockwell 30T scale may be used.
5.3.3 Test tab
5.3.3.1 Single-ended test tabs for the insertion-withdrawal test shall have the configuration shown in Figures 2 to 4 and the dimensions specified in Tables 2 and 3. The "C" dimension tolerance shall be ±0.008 mm (0.0003 in) for brass and ±0.013 mm (0.0005 in) for steel, and raised plateaus around the detent shall be limited to a combined total of 0.03 mm (0.001 in) for both sides.
5.3.3.2 Double-ended test tabs for the temperature and current cycling tests shall be constructed in accordance with Clause 5.3.3.1 and have the configuration shown in Figure 5.
