12、1. This European Standard supersedes EN 60939-1:2005 + corr. Apr.2009. This EN 60939-1:2010 includes the following significant technical changes with respect to EN 60939-1:2005 + corr. Apr.2009: a) Table 3 has been updated, specifying how to handle the Neutral by 3-phase filter with Neutral; b) all
13、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 EN 60068-2-1 for 16 h, using the degree of severity of the lower category temperature as prescribed in the relevant specification; d) since EN
14、 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.

42、relates to passive filter units for electromagnetic interference sup-pression 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. Filters construct
43、ed of capacitive elements where the inductance is inherent in the construction of the filter are within the scope of this specification. Similarly, filters constructed of inductive elements where the capacitance is inherent in the construction of the filter are also within the scope of this generic
44、specification. The manufacturer should state whether a given component is to be designed as a capacitor, an inductor or a filter. The filter units within the scope of this generic specification are further distinguished as those for which safety tests are appropriate (e.g. those connected to mains s
45、upplies) and those for which such tests are not appropriate. A separate sectional specification covers the passive filter units for which safety tests are appropriate. This generic specification establishes standard terms, inspection procedures and methods of test for use in sectional and detail spe
46、cifications within the IECQ-CECC system for electronic components. 1.2 Normative references The following referenced documents are indispensable for the application of this document.
