NF C 61-314 Figure C6 Gauge to Check the Maximum Opening of the Standard V Sheet Cell

This NF C 61-314 Figure C6 Gauge to Check the Maximum Opening of the Standard V Sheet Cell is precision-manufactured in strict compliance with the specifications outlined in NF C 61-314 Figure C6, designed specifically to verify the maximum opening of contact tubes (for 16A applications). It serves as a critical quality control tool to ensure that the cell opening of electrical contact components meets the standard’s rigorous dimensional requirements—with the core criterion that the gauge can be inserted into the cell without force. By providing accurate and consistent verification, it helps safeguard the safety, compatibility, and performance of electrical products adhering to NF C 61-314 standards.

Specifications:
• Fully conforms to NF C 61-314 Figure C6 standard requirements
• Tailored for 16A contact tube applications
• Key diameter (D): 5.11 mm
• Dimensional tolerance: +0/-0.01 mm
• Engineered for interference-free insertion into the contact tube cell (no force required)
• Manufactured from high-precision materials to maintain dimensional stability and durability
• Designed to match the structural and dimensional criteria of standard V sheet cells as specified in NF C 61-314

Test Procedures:
• Inspect the gauge for any damage, deformation, or contamination, and confirm its diameter and tolerance comply with NF C 61-314 Figure C6 specifications.
• Prepare the 16A contact tube sample, ensuring the cell (alvéole) is clean, free from burrs, and undamaged to avoid interfering with test results.
• Place the contact tube in a stable, well-lit fixture to keep it securely positioned during testing.
• Align the gauge with the opening of the contact tube cell, ensuring proper concentricity between the gauge and the cell.
• Attempt to insert the gauge into the cell using only gravity or minimal, gentle pressure—no forced insertion is permitted per the standard.
• Verify if the gauge can be fully inserted into the cell without resistance (in line with the requirement “Il doit être possible d’introduire le calibre dans l’alvéole sans forcer”).
• Remove the gauge slowly and inspect both the gauge and the cell for any signs of wear or damage.
• Record whether the sample meets the standard: a successful interference-free insertion indicates compliance with the maximum opening requirement.
• Document test results, including any instances where insertion requires force (indicating non-compliance) and note relevant observations.

Applications:
• Quality control testing of 16A contact tubes in manufacturing facilities to verify compliance with NF C 61-314 Figure C6 dimensional requirements.
• Compliance assessment by certification bodies and third-party testing laboratories for electrical products adhering to French NF C 61-314 standards.
• R&D testing for the design optimization of contact tubes, ensuring the cell opening meets safety and compatibility guidelines.
• Routine inspection of production lines producing electrical connectors, sockets, or contact components for 16A applications.
• Dimensional verification of contact tube components supplied by vendors to ensure conformance with NF C 61-314 specifications.
• Post-production quality audits for electrical equipment (e.g., industrial sockets, power connectors) relying on 16A contact tubes to meet standard requirements.
• Quality assurance for manufacturers exporting electrical products to markets requiring NF C 61-314 compliance.
