Product No: GNGPL-57C4
CEE 7 Gauge C 4 for Acceptance of Two-pole Plugs with Side Earthing-contacts is specialized in verifying the structural and dimensional compliance of 10/16A 250V two-pole socket-outlets with side earthing-contacts, strictly adhering to CEE7 standards. It is precision-manufactured to meet rigorous 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 with side earthing-contacts can be fully inserted into the tested socket-outlets without undue force, in line with standard specifications.

Test Procedures:
• Prepare the test gauge and the 10/16A 250V two-pole socket-outlet with side earthing-contacts, ensuring both are clean, free from debris, damage, or deformation that may affect test validity.
• Confirm the gauge’s dimensions, surface condition, and hardness comply with CEE7 standard requirements prior to testing.
• Align the gauge’s pins with the contact openings and side earthing contacts of the socket-outlet as specified in Fig.4 of the standard.
• Attempt to insert the gauge’s pins fully into the socket-outlet, applying only gentle and consistent force without excessive pressure.
• Verify whether the pins can be completely inserted into the socket-outlet as required, checking for smooth insertion without obstruction or abnormal resistance.
• Inspect the fit between the gauge and the socket-outlet’s side earthing contacts to ensure structural and dimensional conformity.
• Record the test result, confirming whether the socket-outlet meets the acceptance criteria for two-pole plugs with side earthing-contacts per CEE7 standards.
• After the test, carefully remove the gauge and store it in a dry, dust-free environment to preserve its precision and service life.
