What are the domestic and international EMC (electromagnetic compatibility) standards for intermediate frequency therapy devices?

Medium-frequency therapy devices (used for pain and muscle rehabilitation) must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They generate medium-frequency AC or modulated current of 1kHz-100kHz to act on the human body. Standards require that the frequency and amplitude of the output current be stable, the waveform undistorted, and unaffected by internal oscillation circuit noise and external interference. Simultaneously, the conducted interference generated by the device must meet standards to avoid affecting other equipment sharing the power grid. The devices are typically used in homes or clinics, requiring moderate environmental adaptability.
