CEI-23-50 Foglio di normalizzazione C6 (ex CEI UNEL 09320-64) Calibro per il controllo dell’allargamento massimo dell’alveolo di terra delle spine S31 e degli alveoli di fase della presa P30

This CEI-23-50 Foglio di normalizzazione C6 (ex CEI UNEL 09320-64) Calibro per il controllo dell’allargamento massimo dell’alveolo di terra delle spine S31 e degli alveoli di fase della presa P30 is a specialized calibration gauge designed to inspect the maximum expansion of the earth socket of specific plugs and the phase sockets of matching sockets, strictly complying with the CEI 23-50 standard (formerly CEI UNEL 09320-64). It serves as a critical quality and safety verification tool for electrical connection components used in household and similar applications, ensuring that the socket expansion dimensions remain within specified limits. This precision inspection guarantees reliable electrical contact, stable grounding performance, and compatibility between plugs and sockets, while preventing potential hazards such as poor connections or electrical failures.

Specifications:
• Complies with CEI 23-50 “Spine e prese per usi domestici e similari – Parte 1: Prescrizioni generali” C6 (ex CEI UNEL 09320-64)
• Application scope: Inspection of maximum expansion for earth sockets of specific plugs and phase sockets of matching sockets
• Key dimension: 6.4+0.01 mm
• Core requirement: The gauge shall not enter the socket beyond the specified limit (verifying expansion does not exceed standard requirements)
• Material: High-precision steel (ensuring dimensional stability and durability for repeated use)
• Dimensional tolerance: Tightly controlled to meet standard’s precision requirements for accurate expansion detection

Test Procedures:
• Prepare the plug (earth socket) or socket (phase socket) under test, ensuring the socket area is clean, intact, and free from debris, deformation, or wear.
• Inspect the gauge to confirm it meets the 6.4+0.01 mm dimension requirement, with no deformation, corrosion, or damage to the testing surface.
• Align the gauge with the target socket (earth socket of the plug or phase socket of the socket) in the natural insertion direction specified by the standard.
• Apply a steady, moderate force to attempt inserting the gauge into the socket, adhering to the standard’s force guidelines (no excessive pressure).
• Observe the insertion depth: The gauge shall not fully enter or penetrate beyond the limit that indicates excessive expansion.
• Record whether the gauge’s insertion is restricted within the allowable range, confirming the socket’s expansion does not exceed the maximum limit.
• Repeat the test for all relevant sockets (if multiple phase sockets or earth sockets are present) and determine compliance based on consistent adherence to standard requirements.

Applications:
• Quality control testing of plugs (earth sockets) and sockets (phase sockets) during manufacturing processes.
• Compliance verification for electrical connection components used in household, commercial, and office electrical systems.
• Batch product inspection in production facilities to ensure consistent socket expansion dimensional accuracy.
• Conformity assessment by certification bodies and third-party testing laboratories for CEI 23-50 standard compliance.
• R&D and design validation for manufacturers optimizing socket structure and material to control expansion.
• Pre-shipment inspection of plugs and sockets to meet market access requirements for dimensional compliance.
• Compatibility and reliability testing between plugs and matching sockets to ensure stable electrical and grounding performance.
