RS105 Testing Determines EMP Susceptibility of Military and Commercial Electronics
Recently, MET Labs performed High Altitude (or Nuclear) Electromagnetic Pulse (HEMP or NEMP) susceptibility testing of U.S. Navy vendor electronics at an outdoor test area in Maryland. The test method used was RS105 from MIL-STD-461. RS105 addresses the risk of radiated exposure to an EMP event. (CS116 is the MIL-STD-461 test method that addresses conducted... Read More
