12.5mm Test Probe for DIN 40050 and IEC 60529 Compliance

This 12.5mm Test Probe, compliant with DIN 40050 and IEC 60529, serves as a fundamental safety instrument for household and similar electrical appliances, including refrigerators, washing machines, and electric cookers. It is engineered to assess the accessibility of hazardous live components, such as internal wiring or terminal blocks, through appliance enclosures like control panel gaps and door seals, thereby preventing electric shock. The probe features a precision-machined conductive stainless steel tip with a 12.5mm diameter and a heat-resistant insulated handle. It applies controlled force to simulate accidental user contact. Durable and aligned with standards, it is essential for manufacturers to adhere to global appliance safety regulations. Specifications include: 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, such as bent tip, cracked insulation, or 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 according to test guidelines. 3. Hold the insulated handle and align the probe tip with appliance gaps like control knobs and door edges. 4. Insert the probe into the gap with a steady 50N force, stopping 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 include testing refrigerator door seals, washing machine control panel gaps, and electric cooker knobs.
