Test Probe 31 of IEC 61032 – Milling Grinding Probes

Specifications:
• Probe Type: IEC 61032 Figure 14 Test Probe 31 (milling grinding probe for food waste disposers)
• Rod Diameter: 25 mm ± 0.2 mm
• Rod Working Length: 80 mm ± 0.2 mm
• Front Plate Diameter: 60 mm ± 0.2 mm
• Back Plate Diameter: 110 mm ± 0.2 mm
• Total Probe Length: 150 mm ± 0.2 mm
• Material: High-strength metal (resists bending during insertion tests)
• Core Function: Verifies inaccessibility of hazardous mechanical parts in food waste disposer grinding systems
• Applied Force: No appreciable force (mimics accidental contact)

Test Procedures:
• Inspect the probe for damage (e.g., bent rod, cracked plates) that could skew results.
•  Power on the food waste disposer and ensure its grinding system is idle.
•  Hold the probe by the handle, aligning the rod with openings in the disposer’s guard.
•  Gently insert the rod toward the grinding system, stopping if plates contact the enclosure.
•  Check if the rod touches any hazardous mechanical parts.
•  Record whether the disposer meets safety requirements (pass/fail).

Applications:
•  Safety testing of household food waste disposer grinding systems.
•  Compliance checks for commercial food waste processors’ mechanical hazard protection.
•  Verification of food disposer guard effectiveness.
•  IP code-related protection testing for disposer enclosures.
•  Quality control for food waste disposers during manufacturing to prevent mechanical injuries.
