NOTE 1 The test procedure given in EN 61000-4-6 and the acceptance criteria given in 7.2 will be su-
perseded by that given in EN 60255-22-6 when it is published.
NOTE 2 Except for the ITU broadcast frequency band: 47 MHz - 68 MHz where the level is 3 V.
NOTE 3 Applicable only to ports interfacing with cables, the total length of which according to the
manufacturer's functional specification may exceed 10 m.
NOTE 4 10 and 50 MHz is for GIS applications relevant
