IEC 61032 Figure 4 Test Probe D: IP4X Test Probe with 1N Force

This IP4X test probe (Test Probe D) is a specialized tool for verifying electric shock protection and enclosure safety in household and similar electrical appliances. It features a thin yet rigid 1.0mm-diameter wire for simulating tool access, paired with a 35mm circular baffle to prevent over-insertion. The probe applies a precise 1±0.1N thrust—critical for accurate compliance checks—and includes an insulating handle (10mm diameter, 100mm length) for safe operation. It aligns with global standards like IEC and UL, ensuring reliable testing for hazardous part access prevention.

Standards:

Specifications::
Probe Type: IP4X Test Probe D (compliant with IEC 61032 Test Probe D)
Wire Diameter: 1.0 mm (rigid for consistent testing)
Wire Length: 100 mm
Circular Baffle: Diameter 35 mm (prevents excessive insertion into enclosures)
Handle Material: Insulating material (for user safety during testing)
Handle Diameter: 10 mm
Handle Length: 100 mm (for comfortable grip and control)
Applied Thrus: t 1±0.1N (precise force for standard compliance)
Core Function:  Verifies IP4X protection; prevents tool access to hazardous live/mechanical parts

Test Procedures:
1. Inspect the probe for damage (e.g., bent wire, cracked baffle or handle).
2. Place the 35mm circular baffle flush against the appliance’s enclosure surface.
3. Align the 1.0mm wire with enclosure openings and apply 1±0.1N thrust.
4. Check if the wire touches hazardous live parts or the baffle enters the enclosure.
5. Record whether the enclosure meets IP4X and safety access requirements (pass/fail).

Applications:
1. IP4X protection testing of household appliance enclosures (e.g., refrigerators, washing machines) per IEC 60529:2021.
2. Electric shock prevention checks for audio/video devices (e.g., soundbars, DVD players) per IEC 60065:2021.
3. Access protection verification for luminaire housings (e.g., pendant lights) per IEC 60598-1:2020.
4. UL 60335-1:2023 compliance testing for small kitchen appliances (e.g., coffee makers) to block tool access to hazards.
5. Safety testing of industrial small electrical devices (e.g., portable fans) for hazardous part isolation.
