IEC 61010-1 Figure B.1 Rigid Test Finger

IEC 61010-1 Figure B.1 Rigid Test Finger is a specialized safety tool designed for electrical measurement, control, and laboratory equipment. It features a rigid stainless steel finger that mimics human finger access—critical for verifying if hazardous live parts, high-voltage components, or moving mechanisms remain inaccessible. Paired with an insulating nylon handle for safe, non-slip operation, it applies a precise 10N thrust to simulate real-world accidental contact. Strictly aligned with IEC 61010-1 standards, it is durable, dimensionally stable, and essential for manufacturers, labs, and quality teams to ensure equipment safety and prevent electric shock or mechanical injuries.

• Probe Type: IEC 61010-1 Figure B.1 Rigid Test Finger
• Finger Material: Stainless steel (rigid, corrosion-resistant, maintains dimensional accuracy under repeated testing)
• Handle Material: Nylon (insulating, heat-resistant, non-slip for secure grip during precision operation)
• Key Dimensions:
  • Finger Diameter: 12 mm ± 0.1 mm
  • Effective Finger Length: 80 mm ± 0.2 mm
  • Total Length (Finger + Handle): 180 mm ± 0.5 mm
  • Finger Tip: Hemispherical, radius 6 mm ± 0.05 mm (smooth to avoid damaging equipment enclosures)
• Applied Thrust: 10N ± 0.5N (precise force to replicate accidental human contact with measurement equipment)
• Core Function: Verifies inaccessibility of hazardous live/mechanical parts in measurement, control, and laboratory electrical equipment per IEC/UL 61010-1

Test Procedures:

1. Inspect the test finger for damage (e.g., bent steel body, cracked nylon handle) to ensure testing accuracy.
2. Power on the measurement/control equipment and allow it to reach normal operating mode.
3. Hold the nylon handle and align the rigid finger with equipment openings (e.g., control gaps, vent grilles).
4. Apply steady 10N thrust to the finger toward internal hazardous parts.
5. Check if the finger touches any dangerous components (e.g., live circuits, moving knobs).
