BS1363-2 Figure 16 Withdrawal Pull Gauges for Contact Verification

BS1363-2 Figure 16 Withdrawal Pull Gauges for Contact Verification is a precision testing instrument engineered to assess contact effectiveness, structural compliance, and dimensional accuracy of plugs and sockets according to BS 1363 standards, as specified in Figure 16 of BS 1363-2. This tool encompasses two specific gauge variants for focused evaluations, strictly conforming to the standard’s specifications regarding dimensions, tolerances, material properties, hardness, and surface roughness. Featuring a material hardness exceeding 50HRC and a low thermal expansion coefficient, the gauge guarantees stable and reliable performance, providing accurate results for contact effectiveness evaluations through simulated insertion and specified force application.
