IEC 61032 Figure 14 Test Probe 31 – Milling Grinding Probe

This IEC 61032 Figure 14 Test Probe 31 (milling grinding probe) is engineered to verify the inaccessibility of hazardous mechanical components within the grinding systems of food waste disposal units. The probe incorporates a rigid metal rod with precise dimensional specifications—including a 25mm diameter and 80mm working length—coupled with two circular plates (60mm and 110mm diameters) to prevent excessive insertion. Constructed from high-strength metal alloy, the probe maintains structural integrity during verification procedures while remaining maneuverable for laboratory technicians. This instrument is essential for compliance verification with international safety standards including IEC 61032, UL 430, and GB/T standards for food waste disposers.

Technical 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 alloy (maintains dimensional stability during insertion testing)
• Primary Function: Verification of hazardous mechanical part inaccessibility in food waste disposer grinding systems
• Applied Force: Minimal force application (simulates accidental contact scenarios)

Standardized Test Procedures

1. Conduct visual inspection of the probe for any structural damage (e.g., rod deformation, plate fractures) that could compromise measurement accuracy.
2. Activate the food waste disposer unit and confirm the grinding system is in idle state.
3. Grasp the probe handle and align the rod with access openings in the disposer’s protective guard.
4. Insert the rod toward the grinding mechanism with minimal force, ceasing insertion when either plate contacts the enclosure surface.
5. Determine whether the rod contacts any hazardous mechanical components.
6. Document test results as pass/fail based on compliance with safety requirements.

Application Scenarios

• Safety verification testing of residential food waste disposer grinding systems
• Compliance assessment for commercial food waste processor mechanical hazard protection
• Effectiveness validation of food disposer protective guard designs
• IP code-related protection testing for disposer enclosure systems
• Quality control implementation during food waste disposer manufacturing processes
