What are the domestic and international EMC (electromagnetic compatibility) standards for body fat analyzers?

Time：2025-07-26 Views：506次

Share：

Body fat analyzers (bioelectrical impedance analysis, BIA) must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They apply a weak AC signal (typically 50kHz) to the body through electrodes and measure impedance to calculate body fat percentage. Standards require stable amplitude and frequency of the measurement signal (current/voltage), strong anti-interference capabilities of the impedance measurement circuit, and immunity to environmental electromagnetic noise (e.g., power line interference) to ensure the repeatability and accuracy of weight and body fat data.
