Test Procedures

1. Prepare the test environment to ensure compliance with AS/NZS 3112 standard operating conditions for 33ing.
2. Conduct pre-test inspection of the test plug to verify absence of physical damage, wear, or dimensional deviations.
3. Execute full insertion test by completely inserting the test plug into the socket-outlet under evaluation, verifying alignment with AS/NZS 3112 structural requirements.
4. Perform finger protection test during normal insertion, following AS/NZS 3112 Clauses 3.3.4 and 3.8.1 to validate socket-outlet protection against standard test finger intrusion.
5. Measure and document dimensional fit between test plug and socket-outlet to confirm compliance with specified tolerances…
