CEI 23-50 C4 Standardization Sheet (formerly CEI UNEL 09318-64 2P) Pass Gauge for S30, S31, S32 Plug Pin Verification

This CEI 23-50 C4 Standardization Sheet (formerly CEI UNEL 09318-64 2P) Pass Gauge for S30, S31, and S32 Plug Pin Verification is a specialized pass calibration gauge engineered to verify the dimensional compliance of round pins on S30, S31, and S32 plugs, in strict accordance with CEI 23-50 standard requirements (formerly CEI UNEL 09318-64 2P). This instrument serves as an essential quality verification tool for plugs utilized in household and similar applications, ensuring that pin diameters conform to precise dimensional specifications. By confirming that pins pass through the gauge without applied force, it validates plug-socket compatibility, ensures reliable electrical contact, and maintains operational safety.

Specifications:

• Compliance: Conforms to CEI 23-50 “Spine e prese per usi domestici e similari – Parte 1: Prescrizioni generali” C4 (formerly CEI UNEL 09318-64 2P)
• Application Scope: Specifically designed for verifying round pins of S30, S31, and S32 plugs
• Gauge Type: Pass gauge (“Passa” gauge)
• Critical Dimension: 4.86+0.0 mm
• Core Verification Requirement: Plug round pins must pass through the gauge without applied force
• Unspecified Dimensions: Not constrained by the standard’s unified requirements
• Additional Dimensional Reference: 5=85 mm (per product specification)

Test Procedures:

1. Prepare the S30, S31, or S32 plug under test, ensuring all round pins are clean, intact, and free from deformation or excessive wear.
2. Inspect the gauge to verify it meets the 4.86+0.0 mm dimensional requirement and exhibits no damage to the through-hole structure.
3. Select one round pin from the plug and align it with the gauge’s through-hole in the natural insertion orientation.
4. Attempt to pass the pin through the gauge without applying additional force (utilizing only the pin’s own weight or minimal manual guidance).
5. Observe whether the pin passes smoothly through the gauge; the pin meets verification criteria if it passes without force.
6. Repeat steps 3-5 for all round pins on the plug to ensure comprehensive dimensional verification.
7. Document test results; the plug satisfies the s… (truncated)
