DIN 40050/IEC 60529 12.5mm Test Probe for Household Appliance Electric Shock Protection Testing
Leave a Message
The DIN 40050/IEC 60529 12.5mm Test Probe is a precision safety instrument designed for evaluating electric shock protection in household appliances, including refrigerators, washing machines, and ovens. This device assesses whether hazardous live parts, such as internal wiring and terminal blocks, are accessible through appliance enclosure gaps, including control panels and door seals. Constructed with a conductive stainless steel probe featuring a 12.5mm diameter in accordance with standard specifications and an insulated handle, it applies controlled force to simulate potential user contact scenarios. Fully compliant with DIN 40050 and IEC 60529 requirements, this durable and accurate instrument is essential for manufacturers to verify compliance with global electric shock safety standards.
Specifications:
Tool Type: DIN 40050/IEC 60529 12.5mm Test Probe (for household appliance electric shock protection testing)
Key Dimensions:
– Ball Diameter: 12.5 mm
– Baffle Plate Diameter: 4 mm
– Baffle Plate Thickness: 10 mm
– Handle Diameter: 4 mm
Core Function: Evaluates accessibility of hazardous live parts in household appliances; verifies compliance with electric shock protection requirements per applicable standards
Test Procedures:
1. Conduct visual inspection of the probe to ensure no deformation of stainless steel components, insulation integrity, and proper conductivity, then connect to appropriate live-part detection instrumentation.
2. Power the household appliance and configure to standby or normal operating mode as specified in relevant test protocols.
3. Grasp the insulated handle and align the 12.5mm probe tip with appliance enclosure gaps, such as control panel seams or door edges.
4. Insert the probe into the gap with consistent 50N force, advancing until encountering resistance or achieving full insertion depth.
5. Monitor detection instrumentation for signals indicating contact with live electrical components.
6. Document test results: compliance is achieved when no live-part contact is detected; non-compliance requires enclosure modifications to prevent access.
Applications:
1. Electric shock protection evaluation of refrigerators, assessing gaps around door seals and temperature control interfaces per DIN 40050-9:2017.
2. Safety verification for washing machines, examining control panel gaps and detergent compartment openings in accordance with IEC 60529:2013.
3. Compliance testing of electric ovens, verifying prevention of live-part access at door hinges and control interfaces per UL 60335-1:2023.
4. Manufacturing quality control for microwave ovens, evaluating keypad interfaces and ventilation openings.
5. Post-production validation of dishwashers, assessing door latching mechanisms and display panel edges to meet international household appliance safety requirements.
