What are the domestic and international EMC (electromagnetic compatibility) standards for neuromuscular electrical stimulators?

Time：2025-07-26 Views：507次

Share：

Neuromuscular electrical stimulators (NMES) must comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They output low-frequency pulsed currents (typically 1-100Hz) to stimulate muscle contraction. The standards require precise controllability of pulse amplitude, width, and frequency parameters, preventing abnormal output due to interference (e.g., amplitude abrupt changes), and the device itself should not be a significant source of interference. Because it acts directly on the neuromuscular system, the purity and safety of the output are paramount.
