The IEC 60335-2-29 Figure 103 Test Foot Probe is a precision-engineered safety testing instrument specifically designed for household electrical appliances, including washing machines, refrigerators, and electric ovens. This instrument simulates accidental foot contact with appliance bases, lower apertures, or support structures to evaluate two critical safety parameters: protection against electric shock through detection of hazardous live part accessibility, and structural integrity verification to ensure enclosures maintain dimensional stability without deformation or component exposure under applied foot pressure. Manufactured with a conductive stainless steel foot-shaped tip conforming to IEC 60335 dimensional specifications and featuring an insulated handle, the probe applies controlled mechanical force to ensure consistent, standardized testing procedures. This durable and reliable instrument is essential for manufacturers to demonstrate compliance with global household appliance safety regulations, including IEC 60335, UL 1447, UL 82, and relevant GB standards.
Technical Specifications:
Instrument Type: IEC 60335-2-29 Figure 103 Test Foot Probe (for household appliance foot-contact safety evaluation)
Probe (Foot Tip) Material: Stainless steel (high conductivity with resistance ≤ 0.1Ω; corrosion-resistant construction; precision-machined to IEC 60335 foot profile specifications)
Primary Function: Evaluates household appliances for electric shock hazards and structural stability under simulated foot contact conditions; verifies compliance with IEC 60335 safety requirements
Standardized Test Protocol:
1. Conduct preliminary inspection of the probe for physical damage (deformed foot tip, compromised insulation, conductivity degradation) and establish electrical connection between the tip and live-part detection instrumentation.
2. Position the household appliance on a level, stable test surface; energize the unit and configure for normal operational parameters.
3. Grasp the insulated handle and align the foot tip with designated test areas (appliance base clearances, foot support peripheries, lower ventilation apertures).
4. Apply a controlled 150N force to the foot tip, maintaining consistent pressure application for 10 seconds as specified in standard testing guidelines.
5. Monitor for two critical outcomes: (1) detection instrumentation activation indicating contact with hazardous live parts; (2) observable enclosure deformation or structural compromise.
6. Document test results: compliance is achieved when neither live-part contact nor structural deformation is detected; non-compliance occurs if either condition is observed.
