Artificial pollution test procedures were removed as they are now described in EN 60507. Measurement of impulse c

13、urrent has been transferred to a new standard on current measurement (EN 62475). The atmospheric correction factors are now presented as formulas. A new method has been introduced for the calculation of the time parameters of lightning impulse waveforms. This improves the measurement of the time par
