CEI 23-50 C11 Gauge for S31 Plug Earth Socket Minimum Expansion and Retention Testing

CEI 23-50 C11 Gauge for S31 Plug Earth Socket Minimum Expansion and Retention Testing is engineered in strict accordance with CEI 23-50 Normalization Sheet C11 specifications. This precision testing instrument performs verification of two critical safety parameters for S31 electrical plugs: the minimum expansion capability of earth sockets and the mechanical retention capacity of those sockets. By ensuring earth connection structures meet dimensional and mechanical performance requirements, this gauge prevents electrical safety hazards resulting from inadequate socket clamping force or non-compliant dimensions. It serves as an essential compliance verification tool for manufacturers, testing laboratories, and quality control departments involved in the production and certification of household and similar electrical plugs.

Specifications

• Compliant with CEI 23-50 Normalization Sheet C11 standard requirements
• Testing element features critical dimensional parameter of ø4.6±0.05 mm
• Specified total mass of 400 grams for retention performance verification
• Manufactured with strict dimensional tolerances to ensure measurement accuracy and repeatability
• Dedicated to verification of S31 plug earth socket minimum expansion and retention characteristics

Test Procedures

1. Prepare the gauge and S31 plug test specimens, ensuring both are clean and free from deformation or damage that could compromise measurement accuracy.
2. For earth socket minimum expansion verification: Insert the designated testing element into the S31 plug earth socket, ensuring insertion force remains within specified parameters.
3. For retention performance verification: After gauge insertion, allow the instrument to hang freely under its 400g mass, observing whether gravitational force causes disengagement from the earth socket.
4. Document test observations and results for each S31 plug specimen, determining compliance with CEI 23-50 C11 requirements for earth socket performance.
