2、 Partie 1: Gnralits CORRIGENDUM 1 Corrections to the French version appear after the English text. Les corrections la version franaise sont donnes aprs le texte anglais. Replace existing Figure 3 by the following new Figure 3: The time t 1 is the interval of 1,5 min to 2 min between two consecutive

3、overvoltage applications. The times t 2 and t 3 depend on the test circuit parameters and should be as short as possible.
