CEI 23-50 Standardization Sheet C2 Calibration Gauge for Socket Safety Verification

This CEI 23-50 Standardization Sheet C2 Calibration Gauge is a specialized tool 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.

• Complies with CEI 23-50 “Plugs and sockets for household and similar purposes – Part 1: General requirements” C2
• Applicable socket types: Sockets with collar or recess
• 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

Test Procedures:

Prepare the socket under test (equipped with collar or recess) and ensure it is in a clean, unused condition with intact terminals.
