Passive filter units for electromagnetic interference suppression - Part 1: Generic specification
a) table 3 has been updated, specifying how to handle the Neutral by 3-phase filter with Neutral;
b) all details about Quality assessment have been deleted in this edition, because this standard is a safety standard;
c) filters shall be subjected to Test Aa of IEC 60068-2-1 for 16 h, using the degree of severity of the lower category temperature as prescribed in the relevant specification;
