IEC 61032 Test Probe D (Figure 4, Straight Design) – Accessibility Test Finger

IEC 61032 Test Probe D (Figure 4, Straight Design) – Accessibility Test Finger is engineered for IP4X protection verification and electric shock prevention testing of household and similar electrical appliances. The device incorporates a 1.0mm-diameter rigid test rod (100mm length) to simulate tool access, coupled with a 35mm circular baffle that prevents excessive insertion into enclosures. The insulating handle (10mm diameter, 100mm length) ensures operator safety during testing procedures, while applying a calibrated 1±0.1N thrust force—essential for validating that hazardous components remain inaccessible. Note: This configuration does not include a cable; a cabled variant is available for low-voltage testing applications. Compliant with international standards, this test probe delivers reliable performance for regulatory compliance assessments.

Specifications:

• Probe Type: IEC 61032 Test Probe D (straight configuration, non-cabled for IP4X testing)
• Test Rod Diameter: 1.0 mm (rigid construction for consistent access simulation)
• Test Rod Length: 100 mm ± 0.2 mm
• Circular Baffle Diameter: 35 mm ± 0.2 mm (prevents excessive enclosure penetration)
• Handle Dimensions: Diameter: 10 mm; Length: 100 mm
• Handle Material: Insulating material (ensures operator safety during testing procedures)
• Electrical Connection: None (cabled version available for low-voltage hazard verification)
• Applied Thrust Force: 1±0.1N (calibrated force for standard compliance verification)
• Primary Function: Verifies IP4X protection level; prevents tool access to hazardous live or mechanical components

Test Procedures:

1. Inspect the test probe assembly (rod, baffle, handle) for physical damage (e.g., rod deformation, handle fractures).
2. Position the 35mm baffle flush against the appliance enclosure surface.
3. Align the 1.0mm rod with enclosure apertures (e.g., ventilation slots, access gaps).
4. Apply steady 1±0.1N thrust force to the rod toward potential hazardous components.
5. Verify whether the rod contacts hazardous elements or the baffle penetrates the enclosure.
6. Document test results to determine appliance compliance with safety requirements (pass/fail).

Applications:

• IP4X protection testing of household appliances (e.g., washing machines, coffee makers) per IEC 61032 Figure 4 specifications.
• Electric shock prevention verification for audio/video equipment (e.g., soundbars, televisions).
• Accessibility testing for electrical enclosures and consumer electronics.
