CEE 7 C12 Compliance Gauges for 10/16A 250V Two-Pole Side-Earthing Plugs

These precision gauges are engineered to verify dimensional compliance and interchangeability of 10/16A 250V two-pole plugs with side earthing-contacts according to IECEE CEE-7 C12 specifications. The instruments deliver reliable performance through strict adherence to dimensional tolerances, material hardness requirements, and surface finish standards. Manufactured from materials with minimal thermal expansion coefficients, the gauges maintain dimensional stability across varying environmental conditions, ensuring accurate and repeatable test results for plug product validation.

Specifications:
• Current rating compatibility: 10/16A
• Voltage rating compatibility: 250V
• Applicable standard: IECEE CEE-7 “Specification for plugs and socket-outlets for domestic and similar purposes”
• Gauge function: Interchangeability verification for two-pole plugs with side earthing-contacts
• Material hardness: Minimum 50HRC
• Material characteristic: Low thermal expansion coefficient
• Critical dimensions (in mm): 32.6±0.03, ϕ37.1±0.03, 5.1±0.01, 19±0.05
• Radius specifications (in mm): R=0.5, R=1
• Core requirement: Plugs with side earthing-contacts must insert completely into the gauge without excessive force

Test Procedures:
• Establish a clean, level test environment to prevent contamination from affecting measurement accuracy.
• Inspect gauge condition prior to testing, verifying dimensions, surface finish, and hardness meet standard specifications.
• Prepare the two-pole plug with side earthing-contacts for testing, ensuring absence of damage or deformation.
• Align the plug with the gauge insertion port, ensuring proper orientation of side earthing-contacts.
• Insert the plug completely into the gauge without applying excessive force.
