IEC 60939-1-ed.3.0

Annotation of standard text IEC 60939-1-ed.3.0 :

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. La CEI 60939-1:2010 a trait aux filtres passifs dantiparasitage utilises dans les equipements et machines electroniques ou electriques, ou en association avec ceux-ci. Les filtres a voie unique et a voies multiples a linterieur dune enveloppe font partie du domaine dapplication de la presente specification generique. La presente specification generique etablit les termes normalises, les procedures de controle et les methodes dessai utilises dans les specifications intermediaires et particulieres dans le cadre du systeme IECQ-CECC pour les composants electroniques. La presente edition inclut les modifications techniques significatives suivantes par rapport a ledition anterieure: a) Le Tableau 3 a ete mis a jour: il specifie la facon de traiter le Neutre par un filtre triphase avec Neutre; b) Tous les details se rapportant a l"Assurance de la Qualite" ont ete supprimes dans la presente edition, car la presente norme est une norme de securite; c) Les filtres doivent etre soumis a lessai Aa de la CEI 60068-2-1 pendant 16 h en utilisant le degre de severite de la temperature de categorie inferieure prescrite dans la specification appropriee; d) Etant donne que la CEI 60068-2-20 netablit plus de difference entre la Methode 1A et la Methode 1B, mais decrit uniquement la Methode 1, les references a la methode a utiliser sont mises a jour.
