BS 546 Figure 2 5A Withdrawal-pull Gauges for Contact Effectiveness Dia. 0.199 in. 8 oz

BS 546 Figure 2 5A Withdrawal-pull Gauges for Contact Effectiveness Dia. 0.199 in. 8 oz is a precision testing device designed to evaluate the contact effectiveness, structural compliance, and dimensional precision of 5A plugs and sockets in accordance with BS 546 standards, specifically Figure 2 of BS 546 (“Two-pole and earthing-pin plugs, socket-outlets and adaptors. Specification”). This instrument utilizes a withdrawal-pull method to assess critical contact parameters, strictly adhering to the standard’s specifications for dimensions, tolerances, material properties, hardness, and surface roughness. With a material hardness exceeding 50HRC and a low thermal expansion coefficient, the gauge provides stable and reliable performance, ensuring accurate results in validating the contact effectiveness of 5A electrical connection components.

Test Procedures

Prepare the 5A plug or socket sample for testing, ensuring it is free from damage, corrosion, or debris that could affect contact effectiveness or test results. Inspect the gauge to confirm its surface is clean, free from wear or deformation, and that its nominal diameter (0.199 in.) and weight meet BS 546 Figure 2 specifications. Align the gauge with the sample’s contact points in accordance with Cl…
