YY9706.102 specifies the general requirements and tests for electromagnetic compatibility of ME equipment and ME systems. These general requirements and tests are not only general standard requirements, but also serve as the basis for specialized standards The ME system or ME system can operate in its electromagnetic environment in accordance with requirements and does not constitute an unbearable electromagnetic interference capability (electromagnetic compatibility EMC) for anything in that environment The testing items required for electromagnetic compatibility of medical electrical equipment in YY9706.102-2021 include:
Electrostatic discharge test, electrical fast transient pulse group test, surge test, voltage sag short interruption and voltage change test on the power input line, power frequency magnetic field test, harmonic emission test, voltage fluctuation/flicker emission test, radio frequency conduction test, radio frequency radiation test, radiation emission test, and conducted emission test The electromagnetic compatibility immunity test level of medical electrical equipment is above or below level 3, and the test level is not too high. According to the type of product, select the attached testing requirements of the standard for testingReference to electromagnetic compatibility testing standards:
