What are the domestic and international EMC standards for blood culture instruments?

Blood culture analyzers are used to detect microorganisms in blood and must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They determine microbial growth by monitoring changes in CO2 concentration within the culture flask (e.g., fluorescence or barometric methods). The instrument includes a constant-temperature oscillation incubation unit, optical detection, or pressure sensing unit. Standards require that its sensitive growth detection signal be unaffected by the incubator's fan motor, oscillation motor, or external electromagnetic interference, avoiding false positive or false negative alarms.
