Dito Di Prova Articolato OF CEI 23-50 Fig. 2

The Dito di Prova Articolato (Articulated Test Finger) of CEI 23-50 Fig 2 is a specialized safety tool designed for testing access to hazardous live parts in electrical and electronic equipment—common in EU/Italian markets, such as household appliances, industrial control panels, and IT devices. Its 3-joint flexible design mimics the natural movement of a human finger, allowing it to navigate curved or narrow paths (e.g., around wiring or control modules) that rigid probes can’t reach. Crafted from conductive stainless steel (for detecting live components) and paired with a heat-resistant insulated handle, it applies a controlled 10N thrust to simulate accidental contact. 

Specifications:
Tool Type: Dito di Prova Articolato (Articulated Test Finger) – CEI 23-50 Fig 2 compliant; for hazardous part accessibility testing
Core Function: Navigates complex equipment internals via flexible joints; detects accessible hazardous live parts; ensures CEI 23-50 and IEC compliance

Test Procedures:
1. Inspect the articulated test finger for damage (loose joints, bent probe segments, cracked insulation) and confirm conductivity with a test tool.
2. Power on the equipment under test (EUT) and set it to normal operating mode (e.g., household appliance “on” position).
3. Hold the insulated handle, use the 3-joint design to guide the probe into EUT gaps (e.g., control panel seams, vent slots).
4. Apply a steady 10N thrust to the probe—advance until resistance from components or enclosures stops insertion.
5. Check the connected live-part detection instrument for signals (indicating contact with hazardous parts).
6. Record results: Pass if no hazardous contact is detected; Fail if live parts are accessible.

Applications:
1. Testing access to live wires in Italian-market household refrigerators (per CEI 23-50:2018 Fig 2) to prevent electric shock.
2. Quality control for Italian-designed washing machine control modules during manufacturing, ensuring CEI compliance.
3. Post-production testing of non-patient-contact medical devices (e.g., thermometers) for EU markets to meet regional safety standards.
