IEC 60335-2-14 Test Finger Probe with Diameter 125mm Circular Stop Face

The IEC 60335-2-14 Test Finger Probe (125mm Circular Stop Face) is a specialized safety tool built for kitchen machines—like stand mixers, food processors, and electric grinders. It mimics human finger flexibility via an articulated joint, testing if hazardous parts (e.g., rotating blades, live terminals) are accessible during use. Unlike standard probes, it features a 125mm circular stop face (preventing over-insertion) and a fixed 100mm distance between the tip and stop face. Crafted from conductive metal (for live-part detection) with an insulated handle, it applies gentle 10N thrust, strictly complying with kitchen machine safety standards to prevent cuts or electric shock.

Standards:

Specifications:
Tool Type: IEC 60335-2-14 Test Finger Probe (with 125mm circular stop face; for kitchen machine hazardous part testing)
Probe Material: Conductive stainless steel (resistance ≤ 0.1Ω; corrosion-resistant; 1 articulated joint for flexibility)
Handle Material: Silicone-coated ABS plastic (fully insulated, resistance ≥ 100MΩ; heat-resistant up to 120°C; ergonomic grip)
Joint Characteristics: 1 pivot joint; max bending angle: 90° ± 10°; maintains structure under 10N thrust; fits kitchen machine gaps (≥6mm)
Key Dimensions:
– Circular Stop Face Diameter: 125mm ± 0.5mm
– Distance (Probe Tip to Stop Face): 100mm ± 0.2mm
– Probe Tip Diameter: 12mm ± 0.1mm (matches IEC 61032 Test Probe B)
– Total Length (Probe + Handle): 320mm ± 0.5mm
Applied Thrust: 10N ± 0.5N (simulates light human finger contact; standard for kitchen machine safety testing)
Core Function: Verifies kitchen machines block access to hazardous parts; prevents cuts/electric shock; meets IEC 60335-2-14 requirements

Test Procedures:
1. Inspect the probe for loose joints, bent tips, or cracked insulation; confirm conductivity with a test tool.
2. Power on the kitchen machine under test (EUT, e.g., a food processor) and set it to normal operating mode.
3. Hold the insulated handle, use the joint to guide the probe into EUT gaps (e.g., blade housing seams, control panel slots).
4. Advance the probe until the 125mm stop face touches the EUT; apply steady 10N thrust if needed.
5. Check the connected live-part detector for signals (indicating contact with hazardous parts/blades).
6. Record results: Pass if no contact; Fail if the probe reaches dangerous components.

Applications:
1. Testing blade housing gaps in stand mixers (per IEC 60335-2-14:2020 Clause 20.2) to block access to rotating beaters.
2. Verifying control panel slots in electric food grinders (compliant with UL 60335-1:2023) to prevent contact with live wiring.
3. Safety checks for coffee maker grinding chamber seams (per IEC 61032:2017 Figure 2) to avoid finger cuts from burrs.
4. Quality control for commercial-grade blenders during manufacturing, ensuring IEC 60335-2-14 compliance.
5. Post-production testing of dough mixer accessory ports to meet global kitchen machine safety standards.
