Test Probe 2 of IEC 61032 – 12.5mm Steel Sphere

This IEC 61032 Test Probe 2 is a specialized 12.5mm steel sphere tool built to check if electrical appliance enclosures block small solid objects from entering—critical for preventing contact with hazardous live or mechanical parts. Made from durable stainless steel, it resists rust and keeps precise dimensions for consistent testing. Lightweight and easy to handle, it simulates real-world scenarios (like small items accidentally hitting enclosures) and aligns with global safety standards. It’s a go-to tool for compliance checks on household and industrial devices, ensuring they meet strict protection requirements.

Standards:

Specifications:
Probe Type: IEC 61032 Test Probe 2 (12.5mm steel sphere for solid object protection testing)
Steel Sphere Diameter: 12.5 mm ± 0.1 mm (precision-machined for standard compliance)
Material: Stainless steel (rust-resistant, durable for repeated testing)
Surface Finish: Smooth (avoids scratching appliance enclosures during use)
Core Function: Verifies enclosures block 12.5mm solid objects (IP2X protection) to prevent access to hazards
Applied Force: No appreciable force (mimics accidental contact with small objects)

Test Procedures:
1. Inspect the steel sphere for damage (e.g., dents, rust) that could skew size accuracy.
2. Identify openings on the appliance’s enclosure (e.g., vents, gaps).
3. Gently press the sphere against each opening from different angles.
4. Check if the sphere enters the enclosure or touches hazardous parts.
5. Record whether the enclosure meets safety requirements (pass/fail).

Applications:
1. IP2X protection testing of household appliances (e.g., refrigerators, washing machines) per IEC 61032:2021 Figure 3.
2. Safety checks for electronic device housings (e.g., power adapters, routers) to block 12.5mm objects (IEC 60529:2021).
3. Compliance testing for industrial control box enclosures to prevent small solids from reaching live parts.
4. Quality control for portable electric fan grilles to ensure 12.5mm sphere inaccessibility.
5. Safety verification for small kitchen appliances (e.g., toaster ovens) during manufacturing.
