IECEE CEE-7 Standard Pin Diameter Gauge C9 for Two-Pole Plugs and Socket-Outlets with Pin-Type Earthing-Contact

CEE7 Gauges C 9 for Pin Diameter for Two-pole Plugs and Two-pole Socket-outlets with Pin-type Earthing-contact is specialized in testing and inspecting the pin diameter of two-pole plugs (2.5A 250V and 10/16A 250V) and two-pole socket-outlets equipped with pin-type earthing-contact, ensuring their structure and size comply with the IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”). It features dimensions, tolerances, material quality, hardness, and surface roughness that all meet standard requirements, with a small thermal expansion coefficient of the material to guarantee stable and reliable dimensional accuracy during use.

Specifications:

• Complies with IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”)
• Material hardness: More than 50HRC
• Material thermal expansion coefficient: Small
• Dimensions and tolerances: Stable and reliable
• Surface roughness: Meets standard requirements
• Edges: Slightly rounded
• Rated current ranges: 2.5A 250V, 10/16A 250V
• Gauge types: “Go” gauges and “Not go” gauges

Test Procedures:

1. Select the corresponding “Go” gauge and “Not go” gauge based on the rated current (2.5A or 10/16A) of the two-pole plug or socket-outlet to be tested.
2. Attempt to pass the pin of the plug (or the relevant pin part of the socket-outlet) through the “Go” gauge without applying undue force.
3. Try to pass the same pin through the gap in the “Not go” gauge without using excessive force.
4. Verify compliance: The pin should pass through the “Go” gauge smoothly, and should not pass through the “Not go” gauge; if both conditions are met, the product meets the standard requirements.

Applications:

• Testing and inspecting the pin diameter of 2.5A 250V and 10/16A 250V two-pole plugs with pin-type earthing-contact.
• Testing and inspecting the pin diameter of 10/16A 250V two-pole socket-outlets with pin-type earthing-contact.
