IEC 60601-2-26 and IEC 60601-2-40

IEC 60601-2-26 covers electroencephalographs; IEC 60601-2-40 covers electromyographs and evoked response equipment. They cover amplifier accuracy and noise, input impedance, common-mode rejection, the calibration signal, and stimulator output limits for evoked responses. A PC connected in the patient environment makes the whole set a medical electrical system under IEC 60601-1 clause 16.
