CEE7 Gauge C 9 for Pin Diameter Testing

CEE7 Gauge C 9 is designed for precise testing and inspection of pin diameter in two-pole plugs (2.5A 250V and 10/16A 250V) and socket-outlets with pin-type earthing-contact, ensuring compliance with the IECEE CEE-7 standard. The gauge features dimensions, tolerances, material quality, hardness, and surface roughness that meet all standard requirements. It has a low thermal expansion coefficient to maintain dimensional accuracy. Specifications include:

• Compliance with IECEE CEE-7 standard
• Material hardness: >50HRC
• Small thermal expansion coefficient
• Reliable dimensions and tolerances
• Standard-compliant surface roughness
• Slightly rounded edges
• Rated current: 2.5A 250V, 10/16A 250V
• Types: “Go” and “Not go” gauges

Test Procedures:

1. Select appropriate “Go” and “Not go” gauges based on the plug or socket-outlet’s rated current.
2. Insert the plug pin through the “Go” gauge without undue force.
3. Attempt to pass the pin through the “Not go” gauge without excessive force.
4. Verify compliance: The pin must pass the “Go” gauge smoothly and not pass the “Not go” gauge to meet standards.

Applications:

• Testing pin diameter of 2.5A 250V and 10/16A 250V two-pole plugs with earthing-contact.
• Testing pin diameter of 10/16A 250V two-pole socket-outlets with earthing-contact.
• Quality inspection and compliance verification.
