UL 60335-2-24 Figure 101.DVA.1 Articulated Probes 3.5-4.5 Year Age – BONAD Test Probe
Key standards & compliance:
- UL 60335-2-24: Compliant with Figure 101.DVA.1 specifications for hazard assessment in household and commercial refrigeration systems.
- Child Safety Focus: Validates accessibility and force thresholds for children aged 3.5–4.5 years.
- Design Precision: Matches exact dimensions and joint configurations outlined in UL standards (e.g., tapered finger tip, 6mm hinge pin, 90° bend restriction).
Applications:
- Refrigeration Safety Testing: Evaluates pinch points and moving parts in refrigerators, freezers, and HVAC systems.
- Accessibility Checks: Determines if openings can be penetrated by the probe or if forces exceed 22.2 N during contact.
- Child Hazard Mitigation: Ensures compliance with safety regulations to prevent injuries from rotating blades, hinges, or mechanical components.
Features:
- Durable Construction: Stainless steel probe with a lightweight nylon handle for repeated use and corrosion resistance.
- Force Measurement Compatibility: M6 thread hole for attaching force gauges to quantify mechanical risks accurately.
- Anatomically Accurate Design:
- Tapered Finger Tip: Mimics child finger dimensions, tapering from tip to joint.
- Articulated Joints: Equally spaced joints replicate natural hand movement, restricted to 90° bending at the wrist.
- Rotational Flexibility: Center pin allows hand rotation equivalent to child interaction.
- Standardized Testing: Aligns with UL 60335-2-24 Figure 12DV, 101.DVA.1, and 101.DVA.2 requirements.
