AS/NZS 3112 Figure C1 Three-Pin Test Plug for Checking Three-Pin Flat-Pin 250 V Max. Socket-Outlets

AS/NZS 3112 Figure C1 Three-Pin Test Plug for Checking Three-Pin Flat-Pin 250 V Max. Socket-Outlets is specifically designed to verify whether three-pin flat-pin socket-outlets (with a maximum voltage of 250 V) comply with the requirements of AS/NZS 3112, particularly focusing on structural and dimensional conformance through full insertion tests and finger tests during normal insertion. It adheres to strict standard specifications for reliability and accuracy, making it an essential tool for quality inspection in relevant industries.

Test Procedures
• Prepare the test environment to ensure it meets the standard operating conditions for AS/NZS 3112-related tests.
• Inspect the test plug for any physical damage, wear, or dimensional deviations before use.
• Perform the full insertion test by inserting the test plug completely into the socket-outlet under test, verifying if the insertion process aligns with structural requirements.
• Conduct the finger test during normal insertion, following the provisions of AS/NZS 3112 Clauses 3.3.4 and 3.8.1 to check the socket-outlet’s protection against the standard test finger.
• Measure and record the dimensional fit between the test plug and the socket-outlet to confirm conformance with specified tolerances.
• Evaluate whether the socket-outlet meets AS/NZS 3112 standards based on the test results from steps 3 to 5.

Applications
• Quality inspection and compliance verification of three-pin flat-pin socket-outlets in the electronics industry.
• Routine testing and performance validation of electrical appliances equipped with compatible socket-outlets.
• Conformance testing for manufacturers producing plugs and sockets to ensure alignment with AS/NZS 3112 standards.
• Inspection and auditing processes in related industries requiring adherence to Australian/New Zealand electrical product specifications.
