Bibliography
Provides methods for the evaluation of the effectiveness of shielding measures against LEMP for structures with information equipment such as electronic systems in case of direct and nearby lightning strikes. In addition it provides rules for bonding measures inside structures and for earthing methods relating to LEMP.
