Product No: GNGPL-57C3
Gauges of CEE 7 C3 for 10/16A 250V Two-pole Socket-outlets is tailored for verifying the structural and dimensional compliance of 10/16A 250V two-pole socket-outlets with IECEE CEE-7 standards. It is precision-engineered to meet strict requirements for dimensions, tolerances, material quality, hardness, and surface roughness. With material hardness exceeding 50HRC and a low thermal expansion coefficient, the gauge maintains stable and reliable dimensional accuracy, ensuring that two-pole plugs can be fully inserted into the tested socket-outlets without undue force—consistent with standard specifications.

Test Procedures:
• Prepare the test gauge and the 10/16A 250V two-pole socket-outlet to be tested, ensuring both are clean, free from debris, damage, or deformation that may affect test results.
• Confirm the gauge’s dimensions and surface condition comply with IECEE CEE-7 C3 standard requirements before starting the test.
• Align the gauge’s pins with the contact openings of the socket-outlet in accordance with the orientation specified in Fig.3 of the standard.
• Attempt to insert the gauge’s pins fully into the socket-outlet, applying only gentle and steady force without excessive pressure.
• Verify whether the pins can be completely inserted into the socket-outlet as required by the standard, checking for any obstruction or resistance that indicates non-compliance.
• Inspect the fit between the gauge and the socket-outlet to ensure structural and dimensional conformity.
• Record the test result, confirming whether the socket-outlet meets the two-pole plug acceptance criteria of IECEE CEE-7 C3.
• After the test, remove the gauge carefully and store it in a dry, dust-free environment to preserve its precision.
