IEC 61032 50mm Test Ball – Test Probe 1

The IEC 61032 50mm Test Ball Test Probe 1 is a precision safety tool designed to test if equipment openings (e.g., vents, gaps, or access slots) can block the entry of 50mm-diameter objects—preventing foreign-body intrusion and protecting internal components (like wiring or circuits) from damage. Crafted from solid stainless steel, it delivers consistent, controlled force to simulate real-world scenarios (e.g., accidental insertion of small objects into household or industrial gear). Lightweight yet durable, it strictly complies with IEC 61032, making it ideal for testing equipment (e.g., household appliances, office printers) and ensuring compliance with global safety regulations.

Standards:

Specifications:
Tool Type: IEC 61032 50mm Test Ball Test Probe 1 (for foreign-body protection testing of equipment openings)
Material: Solid stainless steel (density: 7.85g/cm³; corrosion-resistant; no deformation under standard test force)
Key Dimensions:
– Diameter: 50mm ± 0.1mm
– Calculated Weight: ~510g ± 10g (based on spherical volume formula: (4/3)πr³ × material density, r=25mm)
– Optional Attachment: Threaded base (for secure mounting on test stands)
Surface Treatment: Smooth, deburred finish (prevents scratches on tested equipment; ensures even force distribution)
Typical Applied Force: 20N ± 2N (standard for foreign-body testing; simulates moderate pressure from object insertion)
Core Function: Tests if equipment openings block 50mm-diameter objects; prevents foreign-body intrusion into internal components; ensures IEC 61032 compliance

Test Procedures:
1. Inspect the test ball for damage (dents, cracks, or rough surfaces) to ensure accurate testing.
2. Secure the equipment under test (EUT) on a flat, stable surface—align the target opening (e.g., appliance vent).
3. Hold the test ball or mount it on a test stand, positioning it directly in front of the EUT’s opening.
4. Apply a steady 20N force to push the ball toward the opening; stop if the ball is blocked or fully inserted.
5. Check if the ball penetrates the opening (indicating failure) or is blocked (indicating success).
6. Record results: Pass if no penetration; Fail if the ball enters the EUT.

Applications:
1. Testing vent openings in household refrigerators (per IEC 61032:2017 Figure 5.1) to block 50mm objects from hitting internal coils.
2. Verifying door gaps in washing machines (compliant with UL 60335-1:2023) to prevent foreign bodies from damaging the drum.
3. Safety checks for office printer access slots (per EN 60529:2013) to stop small objects from jamming internal mechanisms.
4. Quality control for small industrial control boxes (ventilation gaps) during manufacturing, ensuring foreign-body protection.
5. Post-production testing of microwave oven side-panel slots to meet global household appliance safety standards.
