AS/NZS 3112:2017 Figure G1 Three-Pin Test Plug with Flat and Round Pins for Full-Insertion and Finger Access Prevention Testing

This AS/NZS 3112:2017 Figure G1 Three-Pin Test Plug with Flat and Round Pins for Full-Insertion and Finger Access Prevention Testing is precision-engineered to comply with the exact specifications outlined in AS/NZS 3112:2017 Figure G1, the normative standard for electrical plugs and sockets in Australia and New Zealand. The device is specifically designed for two critical electrical safety compliance tests: full-insertion verification and finger access prevention during normal insertion testing. It features both flat and round pin configurations to accurately simulate real-world plug insertion scenarios and verify socket safety requirements.

By validating proper insertion depth and preventing finger access to live parts, this test plug ensures electrical products meet the rigorous safety and performance requirements of AS/NZS 3112, protecting users against electric shock hazards and ensuring regulatory compliance.

Technical Specifications

• Full compliance with AS/NZS 3112:2017 standard requirements, specifically Figure G1 normative specifications
• Three-pin configuration with dual pin types: flat and round (covering variants: two flat live pins + one round earth pin; two round live pins + one flat earth pin)
• Critical dimensional tolerance: Pin length 38.0±0.03 mm (for both flat and round pins)
• Angular tolerance for pin bevels: 60°±10′
• Spherical radius specifications: S R6±0.5 mm; additional spherical radius 0.3±0.05 mm
• Engineered with precise pin spacing and alignment to replicate standard plug dimensions
• Manufactured from high-quality, durable materials to maintain dimensional stability and ensure repeatable test results
• Designed to facilitate both full-insertion verification and finger access prevention testing procedures

Test Procedures

• Inspect the test plug for any damage, deformation, or dimensional deviations, and confirm its pins, bevels, and radii comply with AS/NZS 3112:2017 Figure G1 specifications.
• Prepare the socket sample, ensuring it is clean, free from burrs, loose components, or structural defects that may affect test results.
• Secure the socket…
