12.5mm test probe for the DIN 40050 and IEC 60529

This 12.5mm Test Probe, compliant with DIN 40050 and IEC 60529, is a core safety tool for household and similar electrical appliances—such as refrigerators, washing machines, and electric cookers. It’s designed to test the accessibility of hazardous live parts (like internal wiring or terminal blocks) through appliance enclosures (e.g., control panel gaps, door seals) to prevent electric shock. Featuring a precision-machined conductive stainless steel probe (12.5mm diameter) and a heat-resistant insulated handle, it applies controlled force to mimic real-user accidental contact. Durable, standard-aligned, it’s essential for manufacturers to meet global appliance safety regulations.

Specifications:
Tool Type: 12.5mm Test Probe (DIN 40050/IEC 60529 compliant; for household appliance electric shock protection testing)
Probe Material: Stainless steel (high conductivity, resistance ≤ 0.1Ω; corrosion-resistant; maintains 12.5mm diameter precision)
Handle Material: Heat-resistant ABS plastic (insulated, resistance ≥ 100MΩ; ergonomic grip; safe for 80–100°C appliance environments)
Key Dimensions:
– Ball Diameter: 12.5 mm
– Baffle Plate Diameter: 4 mm
– Baffle Plate Thickness: 10 mm
– Handle Diameter: 4 mm
Core Function: Detects if hazardous live parts in appliances are accessible; verifies compliance with electric shock protection standards

Test Procedures:
1. Inspect the probe for damage (bent tip, cracked insulation, poor conductivity) and connect it to a live-part detection instrument.
2. Power on the appliance and set it to standby or normal operating mode (per test guidelines).
3. Hold the insulated handle and align the probe tip with appliance gaps (e.g., control knobs, door edges).
4. Insert the probe into the gap with a steady 50N force—stop when resistance is felt or fully inserted.
5. Check the detection instrument for signals (indicating contact with live parts).
6. Record results: pass if no contact; fail if live parts are accessible.

Applications:
1. Testing refrigerator door seal gaps and temperature control slots (per DIN 40050) to block live-wire access.
2. Checking washing machine detergent drawer gaps and control panel seams (IEC 60529) for electric shock risks.
3. Verifying electric oven door hinges and display panel edges (UL 60335-1) to protect users.
4. Quality control for microwave oven keypad gaps and vent openings during manufacturing.
5. Post-production testing of rice cookers’ lid latches and power button seams to meet global safety rules.
