IEC 60335-2-14 Test Finger Probe with 125mm Circular Stop Face

The IEC 60335-2-14 Test Finger Probe with 125mm Circular Stop Face is a precision-engineered safety testing instrument designed specifically for compliance verification of kitchen appliances including stand mixers, food processors, and electric grinders. This specialized probe simulates human finger articulation through a single pivot joint mechanism, enabling comprehensive accessibility testing of hazardous components such as rotating blades and live electrical terminals during operational conditions.

Engineered to exceed standard probe requirements, this instrument incorporates a precisely calibrated 125mm circular stop face to prevent over-insertion and maintains a fixed 100mm distance between probe tip and stop face. Constructed with conductive stainless steel components (resistance ≤ 0.1Ω) for live-part detection and featuring an insulated silicone-coated ABS plastic handle (resistance ≥ 100MΩ), the probe applies controlled 10N thrust force in strict compliance with IEC 60335-2-14 kitchen appliance safety standards for prevention of laceration and electrical shock hazards.

Core Functionality

This instrument verifies that kitchen appliances effectively prevent access to hazardous moving parts and live electrical components, thereby mitigating risks of laceration and electrical shock. The probe ensures compliance with IEC 60335-2-14 requirements through precise mechanical simulation of finger articulation and controlled force application.

Standardized Test Procedures

1. Conduct pre-test inspection of the probe assembly, verifying joint integrity, tip alignment, and insulation continuity using appropriate test instrumentation.
2. Power the equipment under test (EUT, e.g., food processor) and establish normal operating conditions according to manufacturer specifications.
3. Utilize the insulated handle to manipulate the articulated joint, systematically guiding the probe into EUT access points…
