UL 982 Figure 58.5 and UL 498 Figure 10.1 Test Probe PA190

The UL 982 Figure 58.5 Test Probe PA190 is a precision-engineered safety testing instrument designed to assess the accessibility of hazardous live parts and moving components in household refrigerators, freezers, and similar cooling appliances, in full compliance with UL 982 Figure 58.5 and UL 498 Figure 10.1 standards. This probe incorporates a rigid, precision-machined stainless steel tip to simulate potential accidental insertion into appliance apertures, thereby verifying that hazardous components such as electrical wiring, compressors, or fan blades remain inaccessible under normal operating conditions. Paired with an insulating nylon handle to ensure operator safety and controlled application, the probe applies minimal force to replicate real-world contact scenarios. Manufactured with dimensional stability and durability in accordance with UL requirements, this instrument is essential for manufacturers to validate appliance safety and achieve compliance with North American market regulations, including alignment with IEC 61032 and GB/T 16842 international standards for probe testing.

Technical Specifications:
• Probe Designation: UL 982 Figure 58.5 Test Probe PA190 (for refrigerators/freezers)
• Probe Tip Material: Stainless steel (providing rigidity, corrosion resistance, and maintained tip acuity for precise insertion)
• Handle Material: Nylon (electrically insulating, heat-resistant, and featuring a non-slip surface for controlled manipulation)
• Dimensional Parameters:
– Probe Tip Diameter: 3.2 mm ± 0.05 mm
– Effective Probe Length: 76.2 mm ± 0.2 mm
– Handle Length: 120 mm ± 0.5 mm
– Total Assembly Length: 196.2 mm ± 0.5 mm
• Applied Force Specification: Negligible force (simulating light, inadvertent contact with appliance gaps or slots)
• Primary Function: Verification of inaccessibility to hazardous live or moving parts within household refrigerators, freezers, and ice-making appliances, as per UL, IEC, and GB standards

Standardized Test Protocol:
• Conduct a preliminary inspection of the probe assembly for any physical damage (e.g., tip deformation, handle fractures) to ensure measurement integrity.
• Energize the refrigerator or freezer unit and allow it to stabilize in normal operational mode, including active cooling and ice-making cycles where applicable.
• Securely grip the insulating nylon handle and precisely align the probe tip with designated appliance apertures (e.g., door seal interfaces, ventilation grilles, ice dispenser openings).
• Insert the probe tip into the apertures with minimal applied force, avoiding any action that could induce mechanical damage to the appliance under test.
• Systematically determine whether the probe makes contact with any hazardous internal components (e.g., energized conductors, rotating fan assemblies).
• Document the test outcome against the specified safety criteria, recording a pass/fail determination based on accessibility.

Application Scope:
• Safety compliance testing of household frost-free refrigerators (per UL 982 Figure 58.5) to prevent access to compressor terminal connections and associated wiring.
• Regulatory verification for chest-type and upright freezer configurations.
• Validation testing for built-in kitchen refrigeration units equipped with automatic ice dispensers, ensuring probe inaccessibility to mechanical moving parts.
• Manufacturing quality assurance for compact refrigerators intended for dormitory use, targeting U.S. retail market compliance.
• Post-production safety audits of residential ice makers (both standalone and refrigerator-integrated models) to confirm adherence to UL, IEC, and GB safety standards.
