CEI 23-50 Foglio di normalizzazione C2 Calibri per la verifica della impossibilita di realizzare un contatto simultaneo sui poli attivi di prese con collare o pozzetto

This CEI 23-50 Foglio di normalizzazione C2 Calibri per la verifica della impossibilita di realizzare un contatto simultaneo sui poli attivi di prese con collare o pozzetto is a specialized calibration gauge designed to verify the impossibility of simultaneous contact with the live poles of sockets equipped with a collar or recess, strictly adhering to the CEI 23-50 standard. It serves as a critical safety verification tool for household and similar application sockets, ensuring that the socket design prevents unintended simultaneous contact with live components—thereby mitigating electrical shock risks and safeguarding user safety during use.

Specifications:
• Complies with CEI 23-50 “Spine e prese per usi domestici e similari – Parte 1: Prescrizioni generali” C2
• Applicable socket types: Sockets with collar or recess (prese con collare o pozzetto)
• Rated current compatibility: 10 A and 16 A
• Material: Cold-work tool steel X210Cr12Ku (UNI 2955), Material No. 1.2080
• Test force requirement: 75 N (for gauge insertion attempts)
• Electrical detection requirement: Gauges shall not close the circuit of an electrical detector (minimum 40 V applied between socket live pole terminals)
• Dimensions (10 A, mm):
Calibrated dimension set 1: B=25±0.1, C=16±0.1, D=13±0.1, relevant dimension=-0.01, relevant dimension=19-0.02, L=19.5±0.01
Calibrated dimension set 2: B=23±0.1, C=6.5±0.1, D=32±0.1, relevant dimension=-0.01, relevant dimension=19-0.02, L=19.5±0.01
• Dimensions (16 A, mm):
Calibrated dimension set 1: B=25±0.1, C=20±0.1, D=14±0.1, relevant dimension=5-0.01, relevant dimension=26-0.02, L=19.5±0.01
Calibrated dimension set 2: B=23±0.1, C=7±0.1, D=40±0.1, relevant dimension=5-0.01, relevant dimension=26-0.02, L=19.5±0.01
• Radius specification: R=C/2 (for relevant gauge features)
• Minimum length for Calibro A: 10 mm (10 min.)

Test Procedures:
• Prepare the socket under test (equipped with collar or recess) and ensure it is in a clean, unused condition with intact terminals.
• Select the appropriate gauge variant corresponding to the socket’s rated current (10 A or 16 A) and confirm the gauge meets material and dimension specifications.
• Connect an electrical detector (minimum 40 V) between the live pole terminals of the socket to monitor circuit closure.
• Attempt to insert the gauge into the socket in any direction, applying a steady force of 75 N as specified.
• Observe whether the gauge can achieve simultaneous contact with the socket’s live poles and check if the electrical detector circuit closes.
• Repeat the insertion attempt with the second calibrated dimension set for the same rated current to ensure comprehensive testing.
• Record test results: The socket passes if no simultaneous contact with live poles is achieved and the detector circuit remains open.

Applications:
• Safety compliance testing for household sockets with collar or recess.
• Quality control inspections in socket manufacturing plants for 10 A and 16 A rated products.
• Compliance verification for sockets used in commercial, office, or public facility electrical systems.
• Conformity assessment by certification bodies and third-party testing laboratories.
• R&D and design validation for socket manufacturers optimizing live pole insulation and contact prevention features.
• Pre-market certification testing for sockets to meet CEI 23-50 standard requirements.
• Routine safety audits for electrical systems in residential buildings, hotels, and industrial workshops.
