IECEE CEE-7 C3 Dimensional Verification Gauge for 10/16A 250V Two-Pole Socket-Outlets

IECEE CEE-7 C3 Dimensional Verification Gauge for 10/16A 250V Two-Pole Socket-Outlets is engineered to verify structural and dimensional compliance of 10/16A 250V two-pole socket-outlets with IECEE CEE-7 standards. This precision instrument meets stringent requirements for dimensional tolerances, material quality, hardness specifications, and surface roughness parameters.

With material hardness exceeding 50HRC and a low thermal expansion coefficient, the gauge maintains stable dimensional accuracy, ensuring two-pole plugs can be fully inserted into tested socket-outlets without excessive force—consistent with IECEE CEE-7 C3 standard specifications.

Test Procedures

1. 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.
2. Confirm the gauge’s dimensions and surface condition comply with IECEE CEE-7 C3 standard requirements before starting the test.
3. 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.
4. Attempt to insert the gauge’s pins fully into the socket-outlet, applying only gentle and steady force without excessive pressure.
5. Verify whether the pins can be completely inserted into the socket-outlet…
