Articulate Probe of UL 2200 Figure 8.1

The UL 2200 Figure 8.1 Articulated Probe is a specialized safety tool engineered for commercial kitchen equipment—such as commercial ovens, deep fryers, and industrial dishwashers. It mimics human finger movement via a flexible articulated design, with a knurled 12mm metal tip to navigate tight gaps (e.g., control panel seams, heating element covers) and a 50mm insulating baffle plate to prevent over-insertion. Crafted from conductive stainless steel (for live-part detection) and paired with an insulated handle, it applies a controlled 10N thrust to verify if hazardous live parts, hot components, or mechanical parts are accessible. Strictly compliant with UL 2200, it’s critical for manufacturers to validate anti-shock safety and meet global commercial kitchen equipment regulations.

Standard:

Specifications:
Tool Type: UL 2200 Figure 8.1 Articulated Probe (for hazardous part accessibility testing in commercial kitchen equipment)
Probe Tip Material: Conductive stainless steel (resistance ≤ 0.1Ω; corrosion-resistant; knurled surface for consistent gap navigation)
Handle/Baffle Material: Insulated plastic (handle resistance ≥ 100MΩ; heat-resistant up to 120°C; baffle plate for over-insertion protection)
Joint Characteristics: Articulated design; max bending angle: 90° ± 10° (same plane/direction); maintains structure under 10N thrust
Key Dimensions:
– Knurled Finger Diameter: 12mm ± 0.1mm
– Knurled Finger Length: 80mm ± 0.2mm
– Baffle Plate Diameter: 50mm ± 0.2mm
– Baffle Plate Length: 100mm ± 0.2mm
– Baffle Plate Thickness: 20mm ± 0.1mm
– Total Length (Probe + Handle): 300mm ± 0.5mm
Applied Thrust: 10N ± 0.5N (simulates accidental human contact with commercial appliances; aligns with UL 2200 requirements)
Core Function: Tests access to hazardous live/hot/mechanical parts in commercial kitchen gear; blocks over-insertion via baffle; ensures UL/IEC compliance

Test Procedures:
1. Inspect the probe for loose joints, bent tips, cracked insulation, or damaged baffles; confirm conductivity with a test tool.
2. Power on the commercial kitchen equipment under test (EUT, e.g., a deep fryer) and set it to normal operating mode.
3. Hold the insulated handle, use the articulated joint to guide the 12mm tip into EUT gaps (control slots, heating element covers).
4. Apply steady 10N thrust—stop if the 50mm baffle touches the EUT or resistance blocks insertion.
5. Check the connected live-part detector for signals (indicating contact with hazardous parts).
6. Record results: Pass if no contact; Fail if the probe reaches dangerous components.

Applications:
1. Testing access to live wiring in commercial oven door seams (per UL 2200:2023 Figure 8.1) to prevent electric shock for kitchen staff.
2. Verifying heating element gaps in industrial deep fryers (compliant with IEC 61032:2017 Figure 2) to avoid burns from hot components.
3. Safety checks for commercial dishwasher control panel slots (per UL 60335-1:2023) to block access to internal circuits.
4. Quality control for commercial griddle chassis during manufacturing, ensuring UL 2200 compliance for hazardous part protection.
5. Post-production testing of industrial food warmer side vents to meet global commercial kitchen equipment safety standards.
