EN 62305-2 Protection Against Lightning Part Risk management provides procedure for the

The subject was extensively discussed and result 81X unequivocally determined great
majority (all delegates but FR,ES and PT) that:
– Standard 17-102 and 62305 Standards have the same scope;

– Standard 17-102 not product standard
Hereunder, according 135/02, the basis the decision meeting are presented by
specifically listing the principal conflicting clauses the two Standards.
