CEI 23-50 Standardization Sheet C3 Gauge “Non Pass” for P30 Sockets

This CEI 23-50 Standardization Sheet C3 Gauge “Non Pass” is a specialized calibration tool designed to inspect the pin insertion holes of P30 sockets, strictly complying with the CEI 23-50 standard. It serves as a key quality control instrument for household and similar application sockets, ensuring that the size of the socket’s pin insertion holes meets specified requirements. By preventing the gauge from fully entering the holes, it verifies the socket’s structural integrity and compatibility with corresponding plugs, avoiding potential connection instability or safety hazards caused by oversized holes.

Specifications:
• Complies with CEI 23-50 “Plugs and sockets for household and similar purposes – Part 1: General requirements” C3
• Application scope: Dedicated to inspecting pin insertion holes of P30 sockets
• Gauge type: “Non Pass” (Non Pass) gauge
• Key dimension: 5.66+0.01 mm
• Core requirement: The gauge shall not fully enter the socket’s pin insertion holes
• Unspecified dimensions: Not constrained by the standard’s unified requirements

Test Procedures:
• Prepare the P30 socket under test, ensuring it is in a clean, unused condition with no debris or damage in the pin insertion holes.
• Inspect the gauge to confirm it meets the 5.66+0.01 mm dimension requirement and has no deformation or wear.
• Align the gauge with one of the socket’s pin insertion holes in the intended insertion direction.
• Apply a steady and reasonable force to attempt inserting the gauge into the hole.
• Observe whether the gauge can fully enter the pin insertion hole; the test for this hole passes if full insertion is prevented.
• Repeat steps 3-5 for all pin insertion holes on the P30 socket to ensure comprehensive inspection.
• Record the test results; the socket meets the standard if none of the pin insertion holes allow full entry of the gauge.

Applications:
• Quality control inspection of P30 sockets during manufacturing and testing phases.
