CEE 7 C11 Dimensional Verification Gauges for 10/16A 250V Two-Pole Socket-Outlets and Two-Pole Plugs with Pin-Type Earthing-Contact

CEE 7 C11 Dimensional Verification Gauges for 10/16A 250V Two-Pole Socket-Outlets and Two-Pole Plugs with Pin-Type Earthing-Contact are precision-engineered inspection tools designed to verify structural and dimensional compliance with the IECEE CEE-7 C11 international standard. These gauges provide laboratory-grade verification of maximum contact tube openings for 10/16A 250V electrical connectors, ensuring products meet rigorous safety and interoperability requirements.

Manufactured to exacting specifications, these verification gauges deliver consistent, repeatable measurement performance. All dimensional tolerances, material properties (including minimum 50HRC hardness), surface finish characteristics, and thermal expansion coefficients strictly adhere to IECEE CEE-7 C11 standard requirements. The low thermal expansion coefficient material maintains dimensional stability across varying environmental conditions, ensuring measurement accuracy and reliability for quality control applications.

Technical Specifications

• Rated Current Compatibility: 10/16A
• Rated Voltage Compatibility: 250V
• Applicable Standard: IECEE CEE-7 “Specification for plugs and socket-outlets for domestic and similar purposes”
• Gauge Application: Dimensional verification of two-pole socket-outlets and two-pole plugs with pin-type earthing-contact
• Material Hardness: Minimum 50HRC (Rockwell C scale)
• Material Characteristic: Low thermal expansion coefficient for dimensional stability
• Primary Function: Measurement of maximum contact tube openings
• Compliance Requirement: Gauge must be insertable into contact tubes without application of undue force

Standardized Test Procedures

1. Test Environment Preparation: Ensure testing area is clean, free of dust, debris, or any contaminants that could compromise measurement accuracy.
2. Gauge Pre-Inspection: Verify gauge condition including dimensional accuracy, surface finish quality, and hardness compliance with IECEE CEE-7 C11 specifications prior to testing.
3. Socket-Outlet Testing Protocol: Position socket-outlet securely in test fixture. Align verification gauge with contact tube opening.
4. Plug Testing Protocol: Secure two-pole plug with pin-type earthing-contact in appropriate test fixture. Align verification gauge with contact tube opening.
5. Insertion Test: Attempt gauge insertion into contact tube without applying undue force as defined by standard requirements.
6. Compliance Assessment: Evaluate insertion capability. If gauge cannot be inserted without force application, product fails dimensional compliance verification.
7. Documentation: Record test results including pass/fail status and any relevant observations for quality control documentation.
