The lightning protection components for air-termination systems are tested with Iimp 100 (10/350). Mechanical tests, lightning current tests and compliance with the material-specific tensile strength are some examples here. Table 2. Components for conductors along which the lightning current can spread (at least two conductors) and con- nections the earthing system are tested with Iimp 50 (10/350).

The standardised specifications regarding tensile strength, corrosion resistance and the minimum product dimensions for conductor material must tested, depending the material and product type, and complied with (see also Table 2. Here, they must withstand numerous load tests according conditioning that represents artifi- cial ageing. Additional short-circuit cur- rent tests with currents prove the use for the earthing power installations exceeding a.c.
