General operating envelopes acceptable to the NRC staff are given below in the discussion of the MIL-STD 461G test methods. Likewise, operating envelopes for the IEC 61000-4 test methods have been identified that are comparable to their corresponding MIL-STD counterparts. A discussion on these is also given below. These operating envelopes are acceptable for locations where safety-related I&C systems either are or are likely to be installed and include control rooms, remote shutdown panels, cable spreading rooms, equipment rooms, auxiliary instrument rooms, relay rooms, and other areas (e.g., the turbine deck) where safety-related I&C system installations are planned. The operating envelopes are acceptable for analog, digital, and hybrid system installations. The MIL-STD-461G and IEC 61000-4 test methods that demonstrate EMI/RFI susceptibility compliance are discussed below. These methods are acceptable to the NRC staff for accomplishing EMI/RFI susceptibility testing for safety-related I&C systems intended for installation in nuclear power plants. Where applicable, these standards also
