IEC 61032 Test Probe 18 Small Finger Probe 8.6mm

IEC 61032 Test Probe 18 Small Finger Probe 8.6mm is engineered to simulate potential access by children aged 36 months to 14 years to hazardous components within electrical equipment. The probe incorporates a knurled metal finger with an 8.6mm diameter to replicate realistic contact scenarios, coupled with an insulating handle for operator safety. A 451.6mm handle extension, designed to approximate a child’s arm reach, is included as standard. Both probe joints articulate through a 90° range within the same plane and direction, enabling comprehensive assessment of worst-case access conditions. Note: This configuration does not include an electrical cable; a cabled variant is available separately for low-voltage continuity testing applications. This test probe facilitates compliance with international safety standards to mitigate electrical and mechanical hazards associated with child interaction.

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 (simulates child arm reach)
• Collar Diameter: 38.4 mm ± 0.3 mm
• Joint Movement: 90° articulation in identical plane and direction (both joints)
• Material Composition: Probe: Metal (knurled surface); Handle: Insulating polymer
• Cable Inclusion: None (cabled version available for low-voltage testing)
• Primary Function: Simulation of child (36 months – 14 years) access to hazardous parts in electrical apparatus

Test Procedures:

1. Conduct visual inspection of the probe for physical damage (e.g., deformation of knurled finger, handle fractures).
2. Attach the 451.6mm handle extension when evaluating worst-case access scenarios.
3. Configure both joints to a 90° angle to replicate pediatric hand articulation.
4. Methodically guide the probe tip toward potential access points of hazardous components.
5. Verify whether the probe establishes contact with any hazardous elements.
6. Document test outcome as pass/fail based on equipment’s ability to prevent child access.

Applications:

• Child access safety testing for household appliances (e.g., televisions, washing machines) per IEC 61032 Figure 12.
• Safety validation for child-oriented electronic devices (e.g., educational tablets, portable gaming consoles).
