AS/NZS 3112 Figure 3.6 Lateral Strain Resistance Test Gauge (Three-Pin Configuration)

AS/NZS 3112 Figure 3.6 Lateral Strain Resistance Test Gauge (Three-Pin Configuration) is engineered specifically to assess the lateral strain resistance of plugs and sockets compliant with Australian/New Zealand Standard AS/NZS 3112. This precision instrument is manufactured to meet the exact technical specifications outlined in AS/NZS 3112 Figure 3.6, featuring stable dimensional performance, high material hardness exceeding 50HRC, and reliable tolerance control—making it an essential tool for verifying product compliance and structural integrity in quality assurance laboratories.

Specifications:

• Complies with AS/NZS 3112 “Approval and test specification – Plugs and socket-outlets” Figure 3.6 requirements
• Material: High-grade steel with hardness exceeding 50HRC
• Minimal thermal expansion coefficient ensures dimensional stability across temperature variations
• Critical dimensions and tolerances meet standard specifications (including 1.58±0.02mm, 6.2±0.02mm, 19.94±0.02mm, 42±0.5mm, R6.0±0.5mm, R20mm, 60° bevel angle, 0.3±0.05mm, 5±0.5mm)
• Surface roughness conforms to AS/NZS 3112 standard requirements
• Uniform width and thickness maintained across all three contact pins

Test Procedures:

1. Prepare the AS/NZS 3112-compliant plug or socket sample, ensuring it is free from cracks, deformation, or surface imperfections that could compromise test validity.
2. Inspect the test gauge to verify cleanliness, absence of debris or wear, and confirm all dimensions remain within specified tolerance ranges.
3. Secure the sample in a stable, fixed test fixture to prevent movement during force application.
4. Align the three pins of the gauge with corresponding contact points on the sample per AS/NZS 3112 Figure 3.6 alignment requirements.
5. Apply the specified lateral force to the gauge as mandated by the standard, ensuring uniform and controlled force distribution.
6. Maintain the applied force for the duration specified in AS/NZS 3112 to evaluate the sample’s lateral strain resistance.
7. Following force application, carefully remove the gauge and inspect the sample for deformation, contact loosening, or structural compromise.
