Test Probe 31 of IEC 61032 – Milling Grinding Probes

This IEC 61032 Figure 14 Test Probe 31 is engineered to verify the inaccessibility of hazardous mechanical components within the grinding systems of food waste disposal units. It comprises a robust metal rod with precise specifications, including a 25mm diameter and 80mm working length, complemented by two circular plates with diameters of 60mm and 110mm to prevent excessive insertion. Lightweight yet durable, it facilitates easy handling during tests, ensuring dependable assessment of mechanical safety. Conforming to international standards, it serves as an essential instrument for compliance evaluations of food waste disposers.

• 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 any damage, such as a bent rod or cracked plates, that could affect results.
• Ensure the food waste disposer is powered on and the grinding system is idle.
• Hold the probe by the handle, aligning the rod with openings in the disposer’s guard.
• Carefully insert the rod towards the grinding system, halting if the plates contact the enclosure.
• Determine if the rod contacts any hazardous mechanical components.
• Document whether the disposer satisfies safety criteria (pass/fail).

Applications:

• Safety testing of household food waste disposer grinding systems.
• Compliance evaluations 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 hazards.
