IEC 62305-4:2024 provides requirements for the design, installation, inspection, maintenance, and testing of surge protection measures (SPM) for electrical and electronic systems to reduce the risk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of new informative Annex E and Annex F on the determination of current sharing using modelling and current sharing in PV installations respectively; b) addition of a new informative Annex G on methods of testing of system level behaviour; c) addition of a new informative Annex H on induced voltages in SPD-protected installations.
