BS 546 Figure 5 Minimum Go Gauge for Socket-Outlet

The BS 546 Figure 5 Minimum Go Gauge for Socket-Outlet is a precision dimensional verification instrument engineered to validate the structural and dimensional compliance of socket-outlets with BS 546:1950 standards, specifically as detailed in Figure 5 of BS 546 (‘Two-pole and earthing-pin plugs, socket-outlets and adaptors. Specification’). This specialized testing tool adheres strictly to the standard’s requirements for critical parameters including dimensions, tolerances, material properties, hardness specifications, and surface roughness criteria. The gauge features a precision-engineered design specifically calibrated to verify the minimum acceptable size and fit parameters for socket-outlets as mandated by the standard.

Constructed with material hardness exceeding 50HRC and featuring a low thermal expansion coefficient, the gauge ensures exceptional dimensional stability and reliable performance across varying environmental conditions. This provides accurate confirmation that socket-outlets meet the critical ‘go’ criteria for electrical compatibility and safety compliance. The instrument delivers consistent, repeatable results essential for quality control processes in manufacturing and certification environments.

Test Procedures

1. Prepare the socket-outlet sample for testing, ensuring it is free from physical damage, debris accumulation, deformation, or excessive wear that could compromise test accuracy.
2. Inspect the minimum Go gauge to confirm its surface is clean, free from scratches or dimensional misalignment, and all specifications meet BS 546 Figure 5 requirements.
3. Align the gauge with the socket-outlet’s contact slots and structural features, ensuring proper positioning in accordance with the standard’s geometric guidelines.
4. Attempt to insert the gauge into the socket-outlet smoothly, verifying proper fit and dimensional compliance with the minimum acceptable parameters specified in BS 546.
