Lightning Surge
Resistors are tested in accordance with IEC 60 115-1 using both 1.2/50us and 10/700 pulse shapes. The limit of acceptance is a shift in
resistance of less than 1% from the initial value.

Pulse withstand capacity
The single impulse graph is the result of 50 impulses of rectangular shape applied at one-minute intervals. The limit of acceptance was
a shift in resistance of less than 1% from the initial value. The power applied was subject to the restrictions of the maximum permissible
impulse voltage graph shown.

The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the
average power dissipated in the resistor was equal to its rated power at 70C. Again the limit of acceptance was a shift in resistance of
less than 1% from the initial value.
