MIL-STD-1605 Procedures For Conducting A Shipboard Electromagnetic Interference Emi Survey Surface ShipThis standard provides the procedures for demonstrating compliance with the intra and inter-system electromagnetic compatibility EMC, hull-generated Intermodulation Interference IMI, and electrical bonding requirements of MIL-STD-464 for naval surface ships. In addition, an EMI survey is required for new construction ships and ships receiving overhauls or other major repair work that changes the ships electromagnetic configuration.
