NF C 61-314 Figure C.2 Gauge Apparatus for Plug Grip Testing

This NF C 61-314 Figure C.2 Gauge Apparatus for Plug Grip Testing is precision-engineered to meet the exact dimensional and functional specifications defined in NF C 61-314 Figure C.2, the authoritative standard for household and similar electrical socket systems rated at 6A/250V and 16A/250V. The apparatus is specifically designed to verify the dimensional compliance of plug pin entry holes, ensuring that plug grip (prehension de la fiche) meets the standard’s rigorous requirements for safety and mechanical compatibility.

By accurately simulating the engagement interface between plugs and sockets, this testing apparatus provides reliable verification of entry hole dimensions, thereby ensuring the mechanical compatibility, electrical safety, and proper functional performance of plugs and corresponding sockets that comply with NF C 61-314 standards.

Technical Specifications

• Full compliance with NF C 61-314 standard requirements, specifically aligned with Figure C.2 specifications for plug grip testing procedures
• Designed to verify plug pin entry hole dimensions with target specifications of 5.3mm and 5.8mm as defined in the standard
• Incorporates a simulated engagement face (Face d’engagement simulée) that replicates actual plug-socket mechanical interaction
• Includes fixing means insertion holes (Orifice pour l’introduction du moyen de fixation) and retaining pin holes (Trous pour les broches de maintien) for secure apparatus mounting during testing
• Equipped with integrated measurement devices (Dispositif de mesure) for precise dimensional verification with repeatable accuracy
• Manufactured from high-precision, dimensionally stable materials to ensure measurement consistency and long-term reliability
• Complies with the standard’s design philosophy where the apparatus serves as a reference gauge rather than restricting test equipment design, while maintaining all essential functional requirements

Testing Procedures

• Conduct visual inspection of the gauge apparatus to verify absence of damage, deformation, or surface contamination that could affect measurement accuracy
• Verify proper functionality of all key components including the simulated engagement face and integrated measurement devices
• Prepare test samples (socket or plug components with entry holes) ensuring they are clean, free from burrs, and without structural defects that could compromise test validity
• Position the gauge apparatus according to standard procedures, utilizing the fixing means insertion holes and retaining pin holes for secure mounting
• Execute dimensional verification procedures as specified in NF C 61-314, utilizing the integrated measurement devices for accurate assessment of entry hole compliance
• Document test results with precise measurements and compliance status relative to standard requirements
