IEC 61032 Figure 13 Test Probe 19 (5.6mm Small Finger Probe)

The IEC 61032 Figure 13 Test Probe 19 (5.6mm small finger probe) is engineered to simulate access by children aged 36 months or younger to hazardous parts in electrical equipment and medical devices, in compliance with international safety standards including IEC 61032, UL 60335, and GB/T 16842. This precision test instrument features a 5.6mm-diameter ±0.1mm metallic probe tip with hemispherical geometry (R2.8mm ±0.05mm) for realistic contact simulation, coupled with an insulating handle assembly.

The handle incorporates a 464.3mm ±0.8mm extension component that replicates a child’s arm reach. Testing protocols require application with or without this extension, whichever presents the more stringent access condition. Both articulation joints permit 90° angular movement within the same plane and direction, accurately mimicking pediatric hand and finger articulation patterns.

Technical Specifications:

• Probe Type: IEC 61032 Figure 13 Test Probe 19 (small finger probe for child access simulation)
• Probe Diameter: 5.6 mm ± 0.1 mm (metallic probe tip)
• Handle Extension Length: 464.3 mm ± 0.8 mm (simulates pediatric arm reach)
• Critical Dimensions: 101.6 mm ± 0.3 mm (probe section), 44 mm ± 0.15 mm (joint spacing), 25.9 mm ± 0.2 mm (collar diameter)
• Joint Articulation: 90° angular movement in identical plane and direction (both joints)
• Probe Tip Geometry: Hemispherical configuration (R2.8 mm ± 0.05 mm)
• Material Composition: Probe: Metallic alloy; Handle: Insulating polymer
• Electrical Configuration: Non-cabled standard version (cabled variant available separately for low-voltage continuity testing)
• Primary Function: Simulation of pediatric (≤36 months) access to hazardous components in equipment

Standardized Test Protocol:

1. Conduct visual inspection of probe assembly for mechanical integrity (verify probe straightness, handle integrity, joint functionality).
2. Install the 464.3mm handle extension when evaluating worst-case access scenarios.
3. Configure articulation joints to 90° angular position to replicate pediatric hand movement patterns.
4. Methodically guide the probe tip toward potential access points of hazardous components.
5. Document whether probe contact occurs with hazardous parts.
6. Record test outcome as pass/fail based on equipment’s ability to prevent child access.

Application Domains:

• Pediatric access testing for household appliances (e.g., baby monitors, kitchen appliances)
• Safety validation for consumer medical equipment (e.g., home-use monitoring devices)
• Compliance verification for electrical enclosures and protective barriers
• Quality assurance testing in manufacturing environments
• Laboratory certification testing per IEC 61032 requirements
