CEI 23-50 C3 Non-Pass Calibration Gauge for P30 Socket Pin Hole Inspection

This CEI 23-50 C3 Non-Pass Calibration Gauge for P30 Socket Pin Hole Inspection is a precision “Non-Pass” verification tool engineered to inspect the pin insertion apertures of P30 sockets, with strict compliance to the CEI 23-50 standard. It functions as a critical quality assurance instrument for household and similar application sockets, ensuring that socket pin hole dimensions conform to specified dimensional tolerances. By preventing complete gauge insertion into the pin holes, it validates socket structural integrity and mechanical compatibility with corresponding plug pins, thereby eliminating potential electrical connection instability or safety hazards resulting from oversized apertures.

Technical Specifications

• Compliance Standard: CEI 23-50 “Spine e prese per usi domestici e similari – Parte 1: Prescrizioni generali” C3
• Application Scope: Dedicated to dimensional verification of pin insertion holes in P30 sockets
• Gauge Classification: “Non-Pass” (Go/No-Go) verification gauge
• Critical Dimension: 5.66^+0.01 mm
• Verification Requirement: The gauge must not achieve full insertion into the socket’s pin insertion holes
• Unspecified Dimensions: Not governed by the standard’s unified dimensional requirements

Test Procedure

1. Prepare the P30 socket specimen for testing, ensuring it is in a clean, unused condition with no particulate contamination or mechanical damage in the pin insertion holes.
2. Inspect the calibration gauge to verify it meets the 5.66^+0.01 mm dimensional specification and exhibits no mechanical deformation or surface wear.
3. Align the gauge with one of the socket’s pin insertion holes along the intended insertion axis.
4. Apply controlled, steady insertion force to attempt gauge penetration into the pin hole.
5. Observe whether the gauge achieves full insertion into the pin hole; the test for that specific hole is considered compliant if complete insertion is prevented.
6. Repeat procedural steps 3-5 for all pin insertion holes on the P30 socket to ensure comprehensive dimensional verification.
7. Document test results; the socket specimen meets CEI 23-50 requirements if none of the pin insertion holes permit full gauge insertion.
