AS/NZS 3112 Figure A1 Dimensional Verification Gauge for Three-Pin 250V Maximum Flat-Pin Plugs

AS/NZS 3112 Figure A1 Dimensional Verification Gauge for Three-Pin 250V Maximum Flat-Pin Plugs is engineered for precise dimensional compliance verification of three-pin flat-pin plugs with maximum rated voltage of 250V, in strict accordance with AS/NZS 3112 Figure A1 specifications. Manufactured using high-precision machining techniques and durable materials, this gauge ensures consistent, accurate dimensional measurements to support reliable quality assessment of electrical plugs, making it an essential tool for manufacturers, inspectors, and quality control personnel in the electrical industry.

Specifications:

• Complies with AS/NZS 3112 standard, fully conforming to dimensional requirements specified in Figure A1
• Designed for dimensional verification of three-pin flat-pin plugs with maximum 250V rating
• Material: High-strength steel with hardness exceeding 50HRC for superior wear resistance and deformation resistance
• Dimensional tolerance: Meets AS/NZS 3112 specified precision requirements, with critical dimensions controlled within ±0.02mm tolerance
• Low thermal expansion coefficient ensures dimensional stability across varying test environments (operating temperature range: 15°C – 35°C)
• Surface roughness: Ra ≤ 0.8μm to prevent scratching of test plug surfaces during verification procedures
• Pin spacing and configuration strictly conform to flat-pin plug dimensional standards

Test Procedures:

1. Prepare the three-pin 250V maximum flat-pin plug sample, ensuring it is free from damage, deformation, burrs, or surface contamination that could affect test results.
2. Pre-inspect the verification gauge: Check for surface scratches, wear, or dimensional deviations, and clean with a lint-free cloth to remove any debris.
3. Place the plug sample on a stable, flat test bench and secure with appropriate fixtures if necessary to prevent movement during testing.
4. Align the gauge with the plug’s pin holes and contact areas in strict accordance with orientation specifications in AS/NZS 3112 Figure A1.
5. Gently insert the gauge into the plug’s pin receiving structure with uniform force, ensuring no forced insertion that may damage the sample or gauge…
