The methods of measurement detail the techniques and procedures for
use when measuring fields on site near to an overhead line and also
the techniques and procedures for making laboratory measurements of
interference voltages and currents generated by line equipment and

The procedures for determining limits define the expected values of
radio noise field and the width of the "disturbed corridor"
following the route of the line. This corridor takes into account
the effective field strength of the wanted signal, the
signal-to-noise ratio selected and the expected strength of the
noise field for a given line. The procedures are valid only for
long and medium waves.
