Pulse withstanding 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.
