IECEE CEE-7 Gauge Set C7 for First Contact Distance Measurement in 10/16A 250V Socket-Outlets

The IECEE CEE-7 Gauge Set C7 for First Contact Distance Measurement in 10/16A 250V Socket-Outlets is engineered for structural and dimensional verification of 10/16A 250V two-pole socket-outlets, specifically assessing the distance to the point of first contact. This precision instrument fully complies with the IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”) and is implemented across relevant industrial sectors. All dimensional parameters, tolerance specifications, material properties, hardness characteristics, and surface roughness metrics conform to standard requirements, featuring minimal thermal expansion coefficient and consistently reliable dimensional stability.

Specifications:
• Compliance with IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”)
• Material hardness: Exceeds 50HRC
• Material thermal expansion coefficient: Minimal
• Dimensions and tolerances: Consistently stable and reliable
• Surface roughness: Conforms to standard specifications
• Edge configuration: Non-rounded
• Gauge dimension series: 5.45 mm, 5.60 mm, 5.75 mm, 5.95 mm
• Tolerance specification for 5.45 mm gauge: +0.02 / -0

Test Procedures:
• Select the maximum gauge from the C7A to C7D series that can be inserted into the socket-outlet’s plug pin entry aperture.
• Insert the selected gauge completely into the 10/16A 250V two-pole socket-outlet.
• Verify that the gauge’s short pin does not make contact with the socket-outlet’s contact tubes.
• Confirm that the gauge’s long pin establishes contact with the socket-outlet’s contact tubes upon full insertion.

Applications:
• Structural and dimensional verification of 10/16A 250V two-pole socket-outlets regarding first contact distance.
• Quality assurance and compliance validation within the electronics manufacturing sector.
