Test Probe 18 of IEC 61032 8,6mm Small Finger Probes

This IEC 61032 Test Probe 18 (8.6mm small finger probe) is designed to simulate how children aged 36 months to 14 years might access hazardous parts in electrical appliances. It features a knurled metal “finger” (8.6mm diameter) for realistic contact, paired with an insulating handle. A 451.6mm handle extension (mimicking a child’s arm) is included, and both joints move 90° in the same plane/direction—critical for testing worst-case access. Note: It has no cable; a cabled version is available separately for low-voltage tests. It aligns with global standards to prevent child-related electrical or mechanical hazards.

Standards:

Specifications:
Probe Type: IEC 61032 Test Probe 18 (small finger probe for child access simulation)
Knurled Finger Diameter: 8.6 mm ± 0.1 mm
Probe Head Radius: 4.3 mm ± 0.05 mm (hemispherical tip)
Knurled Finger Length: 57.9 mm ± 0.15 mm (3 knurls, 19.3 mm per knurl)
Handle Extension Length: 451.6 mm ± 0.8 mm (mimics a child’s arm)
Collar Diameter: 38.4 mm ± 0.3 mm
Joint Movement: 90° angle in the same plane and direction (both joints)
Material Probe: Metal (knurled for realistic simulation); Handle: Insulating material
Cable Inclusion: None (cabled version available for low-voltage testing)
Core Function: Simulates child (36 months – 14 years) access to hazardous parts in equipment

Test Procedures:
1. Inspect the probe for damage (e.g., bent knurled finger, cracked handle).
2. Attach the 451.6mm handle extension if testing worst-case access.
3. Adjust the joints to a 90° angle to mimic a child’s hand movement.
4. Gently guide the probe’s tip toward potential access points of hazardous parts.
5. Check if the probe touches any hazardous components.
6. Record whether the equipment blocks child access (pass/fail).

Applications:
1. Child access testing for household appliances (e.g., televisions, washing machines) per IEC 61032:2021 Figure 12.
2. Safety checks for child-friendly electronic devices (e.g., educational tablets, portable game consoles).
3. Verification of small kitchen appliances (e.g., mini blenders, toaster ovens) to prevent mechanical/electrical risks to children.
4. Compliance testing for toy-related electrical products (e.g., battery-powered ride-on toys) with accessible openings.
5. Quality control for commercial child-area equipment (e.g., mall playzone fans, school classroom electronics).
