Test Finger Probe

UL 60335-2-24 Figure 101.DVA.1 Articulated Probe

Brand: SZBONAD

Product Number: BND-ULAP

The UL 60335-2-24 Figure 101.DVA.1 Articulated Probe is a precision-engineered safety testing tool designed to assess hazards posed by moving parts in refrigeration systems and similar appliances. Specifically developed to simulate the interaction of children aged 3.5–4.5 years, this probe ensures compliance with international safety standards by verifying that accessible openings or moving components do not exert harmful force (exceeding 22.2 N / 5 lbf) during contact. Crafted from durable stainless steel with an ergonomic nylon handle, it features a threaded M6 hole for seamless integration with force gauges, enabling accurate measurement of mechanical risks.

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:

  1. Durable Construction: Stainless steel probe with a lightweight nylon handle for repeated use and corrosion resistance.
  2. Force Measurement Compatibility: M6 thread hole for attaching force gauges to quantify mechanical risks accurately.
  3. 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.
  4. Standardized Testing: Aligns with UL 60335-2-24 Figure 12DV, 101.DVA.1, and 101.DVA.2 requirements.
