Test Probe A of IEC 61032 – 50mm Sphere with Baffle and Handle

Specifications:
• Probe Type: IEC 61032 Figure 5 Test Probe A  50mm Sphere with Baffle and Handle
• Test Sphere
– Diameter: 50mm ± 0.5mm
– Material: Non-conductive, impact-resistant plastic (avoids electrical interference)
– Surface: Smooth, burr-free (prevents enclosure scratches)
• Baffle:
– Diameter: 100mm ± 1mm (larger than sphere to block over-insertion)
– Material: Rigid plastic (maintains shape during testing)
– Position: 20mm from sphere surface (per IEC 61032 specs)
• Handle:
– Material: Insulating nylon (heat-resistant, non-slip)
– Length: 150mm ± 5mm (ergonomic for comfortable operation)
• Core Function: Verifies that electrical equipment enclosures block access to hazardous parts via a 50mm spherical object, with baffle preventing excessive insertion

Test Procedures:
• Inspect the probe (no sphere cracks, baffle damage, or handle wear) for functionality.
• Power on the electrical equipment and let it reach normal operating mode.
• Hold the insulating handle and align the 50mm sphere with equipment openings (e.g., vents, gaps).
• Gently press the sphere toward the opening—stop if the baffle contacts the enclosure (prevents over-insertion).
• Check if the sphere touches any hazardous internal parts (live wires, moving components).
•  Record whether the equipment meets safety requirements (pass/fail).

Applications:
• Safety testing of household appliances (e.g., washing machines, air conditioners).
• Compliance checks for industrial electrical control boxes to block large-object access.
• Verification of commercial refrigerators and freezers to prevent debris entry into hazardous components.
• Quality control for outdoor electrical equipment (e.g., garden water pumps) during manufacturing.
• Post-production audits of large consumer electronics (e.g., smart TV enclosures) to meet IEC/UL enclosure safety standards.
