IEC 61032 Figure 1 (Test Probe 1) Rigid Test Finger with Non-Circular Stop Face is a specialized safety tool designed to simulate human finger access, verifying if hazardous live or mechanical parts in electrical equipment remain inaccessible. It features a rigid stainless steel “finger” for consistent testing and a non-circular stop face (e.g., rectangular or hexagonal) that prevents over-insertion into equipment enclosures. Paired with an insulating nylon handle for safe grip, it’s essential for compliance checks across appliances, IT devices, and industrial equipment, ensuring end-user protection from electric shock or mechanical harm.
Specification
- Probe Type: Rigid Test Finger with Non-Circular Stop Face (IEC 61032 Test Probe 1 compliant)
- Finger Material: Stainless steel (rigid, corrosion-resistant, maintains dimensional accuracy)
- Handle Material: Nylon (insulating, non-slip, heat-resistant for safe operation)
- Stop Face: Non-circular
- Key Dimensions:
-Finger Diameter: 12mm ± 0.1mm
-Finger Length (effective): 80mm ± 0.2mm
-Total Length (finger + handle): 180mm ± 0.5mm - Thrust Specification: Not inherently applied by the probe itself. However, when certain compliance standards (e.g., GB/T 4208, IEC 60335, GB 4706) require a specific force such as 10N, 30N, or 50N, the handle can be configured with an optional push-pull gauge to meet those requirements.
- Core Function: Simulates human finger access to verify inaccessibility of hazardous live/mechanical parts in equipment
Test Procedures
- Inspect the test finger for damage (e.g., bent steel, cracked handle, deformed stop face).
- Power on the electrical equipment and let it reach normal operating mode.
- Set up the required force (if any) according to the governing standard—using a force gauge if specified—or proceed with no force if the test method permits.
- Hold the nylon handle and align the stainless steel finger with equipment openings.
- If a specific force is required by the relevant standard, apply the corresponding thrust (e.g., 10N) using a push-pull gauge; otherwise, insert the finger without applying any additional force.
- Check if the finger touches any dangerous components (live wires, moving parts).
- Record whether the equipment meets safety requirements (pass/fail).
Applications
- Safety testing of household appliances (e.g., refrigerators, washing machines).
- Compliance checks for IT/AV equipment (e.g., laptops, soundbars) to block finger access to hazards.
- Verification of small industrial control panels (e.g., workshop sensors).
- Quality control for home medical auxiliary devices (e.g., air purifiers) during manufacturing.
- Post-production safety audits of portable electric tools (e.g., handheld drills) to ensure hazard inaccessibility.
