Description

BS 546 Figure 2 5A Withdrawal-pull Gauge for Contact Effectiveness Verification is a precision testing instrument engineered to evaluate the contact effectiveness, structural compliance, and dimensional accuracy 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 gauge employs a withdrawal-pull methodology to validate critical contact parameters, maintaining strict adherence to the standard’s requirements for dimensions, tolerances, material properties, hardness, and surface roughness. With material hardness exceeding 50HRC and a low thermal expansion coefficient, the gauge ensures stable and reliable performance, delivering precise results for 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… (truncated)
