IEC 60255-22-3 Ed. 3.0 b:2007

Specifies the general requirements for radiated electromagnetic field immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems. The tests are intended to confirm that the equipment under test will operate correctly when energised and subjected to an electromagnetic field. The main change with respect to the previous edition concerns the extension of the frequency range.
