Chapter Testing, maintenance and documentation
. The lightning
protection components for air-termination systems are
tested with Iimp 100 (10/350).
Components for conductors along which the lightning
current can spread (at least two arrestors) and con-
nections the earthing system are tested with Iimp
50 (10/350). After a
conditioning phase lasting days, the components
are impacted with three lightning strikes.1: Critical situations include structures containing sensitive systems, office and commercial buildings or
places which large number people meet.
Components for lightning protec-
tion systems are tested according
to IEC 62561-1. This corres-
ponds test class H. This corresponds test class N.
