CEE 7 C10 Gauge Set for 10/16A 250V Two-Pole Plugs

CEE 7 C10 Gauge Set for 10/16A 250V Two-Pole Plugs is engineered to verify dimensional compliance of 10/16A 250V two-pole plugs with the IECEE CEE-7 standard (CEE7/7). This precision gauge set delivers stable, repeatable performance through strict adherence to dimensional tolerances, material specifications (minimum 50HRC hardness), and surface finish requirements as defined in the standard. The gauge material exhibits minimal thermal expansion coefficient, while edge radii are precisely controlled to ensure accurate dimensional verification without damage to test specimens.

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 Type: C10 (comprising C10 A and C10 B gauges)
• Material Hardness: Minimum 50HRC
• Material Characteristic: Low thermal expansion coefficient
• Edge Design: Controlled radius edges
• Critical Dimension (C10 A and C10 B): 5±0.5 mm
• Verification Criteria: Gauge C10 A must pass outside plug pins without excessive force; Gauge C10 B must pass between plug pins without excessive force

Test Procedure

1. Establish a controlled test environment free of contaminants that could affect measurement accuracy.
2. Verify gauge calibration status, including dimensional accuracy, edge condition, and material hardness per standard requirements.
3. Position the two-pole plug specimen on a stable, level test surface.
4. Align Gauge C10 A with the external surfaces of the plug pins and attempt passage without applying excessive force.
5. Align Gauge C10 B with the inter-pin spacing and attempt passage without applying excessive force.
6. Evaluate compliance: both gauges must pass as specified; failure of either gauge indicates non-compliance with IECEE CEE-7 requirements.
7. Document test results based on C10 A and C10 B gauge performance.

Applications

• Quality control verification of 10/16A 250V two-pole plugs in electrical component manufacturing
• Compliance testing for plug dimensional requirements per IECEE CEE-7 standard
