IEC 61032:2017/IEC 60335-1:2023 Voltage Indicator for Electric Shock Protection

The IEC 61032:2017/IEC 60335-1:2023 Voltage Indicator for Electric Shock Protection (Circuit Test Device) is an essential instrument for validating electric shock safety compliance in electrical equipment, ranging from household appliances to industrial machinery. This device delivers a precisely controlled 40–45V power source (maximum 48V) to simulate human finger, tool, or metal wire contact during IP protection and hazardous part testing procedures. Engineered for compatibility with standard test probes, it incorporates a straightforward design for operational efficiency, accurate voltage output with minimal tolerance, and reliable performance supported by a 2A fuse for enhanced safety. This instrument is indispensable for manufacturers and testing laboratories, ensuring equipment compliance with international shock protection standards to prevent accidental electric injury.

Standard Test Procedure

1. Power on the equipment under test (EUT) and the voltage indicator.
2. Connect one terminal of the indicator to the EUT’s power plug; attach the ground wire according to applicable standards.
3. Connect the indicator’s other terminal to the designated test probe (e.g., articulated finger probe).
4. Apply the standard-specified thrust force with the probe to EUT access points (vents, control slots).
5. Monitor the indicator for voltage signals (indicating contact with hazardous live parts).
6. Record test results: Pass if no voltage signal detected; Fail if hazardous contact is indicated.
