Test Probe 12 of IEC 61032 – Long Test Pin

This IEC 61032 Test Probe 12 (Long Test Pin) is designed to verify if hazardous live or mechanical parts in appliances are inaccessible to accidental contact with tools like screwdrivers. Made from polished stainless steel for durability and precision, it features a slim, rigid design that mimics pointed objects. Equipped with insulating material for safe handling, it aligns with global standards (IEC, UL) to ensure reliable safety checks. Lightweight yet sturdy, it’s easy to maneuver into tight spaces, making it essential for compliance testing across household and industrial appliances.

Standards:

Specifications:
Probe Type: IEC 61032 Test Probe 12 (Long Test Pin for tool-access simulation)
Material: Stainless steel (rigid, corrosion-resistant)
Surface Finish: Polished (prevents scratches on appliance enclosures)
Key Diameters :
-Test pin main diameter: 4 mm ± 0.05 mm
– Insulating component diameter: 25 mm ± 0.2 mm
– Handle/secondary diameter: 10 mm
Insulating Material: Included (for safe user handling during testing)
Core Function: Verifies inaccessibility of hazardous live/mechanical parts to tool-like objects
Applied Force: No appreciable force (mimics accidental tool contact)

Test Procedures:
1. Inspect the probe for damage (e.g., bent pin, cracked insulation).
2. Position the probe near the appliance’s potential access points for hazardous parts.
3. Gently guide the polished stainless steel pin toward openings, simulating tool insertion.
4. Check if the pin touches any hazardous live or mechanical components.
5. Record whether the appliance blocks access (pass/fail).

Applications:
1. Safety testing of household appliances (e.g., blenders, microwaves) to block tool access to hazards (per IEC 61032:2021 Figure 8).
2. Compliance checks for industrial control panels to prevent screwdriver contact with live parts (IEC 60529:2021).
3. Verification of electronic device enclosures (e.g., power supplies) per UL 60335-1:2023 Clause 22.11.
4. Quality control for small kitchen appliances (e.g., coffee makers) during manufacturing.
5. Safety checks for portable electric tools (e.g., drills) to isolate hazardous mechanical parts.
