IECEE CEE-7 Standard Gauges C 6 A and C 6 B

These IECEE CEE-7 Standard Gauges C 6 A and C 6 B are engineered in strict compliance with the IECEE CEE-7 specification, specifically designed for the dimensional verification of installation and fixing compatibility for designated socket-outlet configurations. They ensure socket-outlets accommodate proper assembly and secure mechanical fixation through precise dimensional validation, supporting reliable electrical performance and safety in domestic and similar environments. As essential quality assurance instruments, they perform a critical function in confirming that socket-outlets meet standard requirements for fixing hole alignment and operational feasibility.

Specifications

• Complies with IECEE CEE-7 “Specification for plugs and socket-outlets for domestic and similar purpose” Section C 6
• Available in two calibrated variants: C 6 A and C 6 B
• Dimensional parameters for C 6 A: a = 37.85 ± 0.01 mm, with additional critical dimensions including 4.05 mm and 8.012 mm (as per specification table)
• Dimensional parameters for C 6 B: a = 38.15 ± 0.01 mm, with specified dimension 0 (as per specification table)
• Additional key dimension: 72 ± 0.03 mm (as indicated in product drawings)
• Enables smooth insertion of two gauge pins through socket fixing holes/slots and subsequent rotation with a screwdriver without tilting

Test Procedures

1. Prepare the socket-outlet specimen for testing, ensuring it is clean and free of debris that may affect dimensional measurement accuracy.
2. Select the appropriate gauge variant (C 6 A or C 6 B) based on the socket type and test protocol requirements.
3. Insert the two gauge pins through the fixing holes or slots of the socket-outlet, then guide them sequentially into the holes of both gauge plates.
4. Attempt to rotate the gauge pins using a standard screwdriver, verifying that rotation can be performed smoothly without pin tilting or binding.
5. Confirm that the entire insertion and rotation process meets the standard’s operational requirements to validate compatibility.

Applications

• Quality control and compliance verification for ordinary surface-type socket-outlets
• Installation compatibility testing for electrical components in domestic environments
• Laboratory verification of socket-outlet dimensional compliance with international standards
• Production line testing for socket-outlet manufacturers
• Third-party certification testing for electrical safety compliance
