Gauge for Flat and Round Pin Plugs of AS/NZS 3112 Figure F1

Gauge for Flat and Round Pin Plugs of AS/NZS 3112 Figure F1 is engineered to assess the structural and dimensional compliance of Australian/New Zealand Standard plugs and sockets with AS/NZS 3112, specifically targeting three-pin plugs of two types: those with two flat live pins and a round earth pin, and those with two round live pins and a flat earth pin (as illustrated in Figure 2.1(f) and Figure 2.1(g) of the standard). It adheres to the precise requirements of AS/NZS 3112 Figure F1, featuring stable material properties, accurate dimensions, and reliable tolerances to ensure rigorous and consistent testing results for quality verification.

Specifications

Test Procedures
• Prepare a suitable test environment that meets the operating conditions specified by AS/NZS 3112.
• Visually and physically inspect the gauge to ensure no damage, wear, or dimensional irregularities that could affect test accuracy.
• Identify the type of three-pin plug to be tested (either with two flat live pins + round earth pin or two round live pins + flat earth pin).
• Align the plug pins with the corresponding openings of the gauge (matching Figure F1(a) or F1(b) based on plug type).
• Insert the plug pins through the gauge at all depths of insertion, verifying that they pass easily without obstruction.
• Check the positional disposition of the plug pins against the gauge to confirm compliance with dimensional and structural requirements.
• Record test data and observations, then determine if the plug meets AS/NZS 3112 standards based on the results of steps 4 to 6.

Applications
• Quality control and compliance testing of three-pin plugs (flat/round pin combinations) in the electronics industry.
• Dimensional and structural verification of electrical appliances equipped with AS/NZS 3112-compliant plugs.
• Conformance inspection for manufacturers producing plugs and sockets to ensure alignment with Australian/New Zealand standards.
• Routine auditing and performance validation in industries related to electrical components, plug-and-socket production, and electrical equipment manufacturing.
