Rigid Test Finger for IEC 61010-1 Figure B.1

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’s durable, dimensionally stable, and essential for manufacturers, labs, and quality teams to ensure equipment safety and prevent electric shock or mechanical injuries.

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

Applications:
• Safety testing of digital multimeters and clamp meters (per IEC 61010-1Figure B.1) to block access to live terminals.
• Compliance checks for laboratory power supplies and signal generators.
• Verification of industrial process controllers (e.g., temperature/pressure regulators) for electric shock protection.
• Quality control for medical auxiliary measurement devices (e.g., blood glucose meter testers) during manufacturing.
• Post-production safety audits of benchtop laboratory equipment (e.g., oscilloscopes) to meet global IEC/UL standards
