IEC 60939-1:2010 relates to passive filter units for electromagnetic interference suppression for use within, or associated with, electronic or electrical equipment and machines. Both single and multi-channel filters within one enclosure are included within the scope of this generic specification. This generic specification establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications within the IECQ-CECC system for electronic components. This edition includes the following significant technical changes with respect to the previous edition: 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; d) since IEC 60068-2-20 does no longer make a difference between Method 1A and 1B, but only describes Method 1, references to the method to be used are updated.<\/p>\n
