Passive filter units for electromagnetic interference suppression - Part 1: Generic specification

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.

Passive Filter für die Unterdrückung von elektromagnetischen Störungen - Teil 1: Fachgrundspezifikation

Filtres passifs d'antiparasitage - Partie 1: Spécification générique

La CEI 60939-1:2010 a trait aux filtres passifs d'antiparasitage utilisés dans les équipements et machines électroniques ou électriques, ou en association avec ceux-ci. Les filtres à voie unique et à voies multiples à l'intérieur d'une enveloppe font partie du domaine d'application de la présente spécification générique. La présente spécification générique établit les termes normalisés, les procédures de contrôle et les méthodes d'essai utilisés dans les spécifications intermédiaires et particulières dans le cadre du système IECQ-CECC pour les composants électroniques. La présente édition inclut les modifications techniques significatives suivantes par rapport à l'édition antérieure: a) Le Tableau 3 a été mis à jour: il spécifie la façon de traiter le Neutre par un filtre triphasé avec Neutre; b) Tous les détails se rapportant à l'Assurance de la Qualité' ont été supprimés dans la présente édition, car la présente norme est une norme de sécurité; c) Les filtres doivent être soumis à l'essai Aa de la CEI 60068-2-1 pendant 16 h en utilisant le degré de sévérité de la température de catégorie inférieure prescrite dans la spécification appropriée; d) Étant donné que la CEI 60068-2-20 n'établit plus de différence entre la Méthode 1A et la Méthode 1B, mais décrit uniquement la Méthode 1, les références à la méthode à utiliser sont mises à jour.

Pasivni filtri za dušenje elektromagnetnega motenja - 1. del: Generična specifikacija (IEC 60939-1:2010)

Ta generična specifikacija se nanaša na pasivne filtre za dušenje elektromagnetnega motenja za uporabo pri elektronski ali električni opremi ali napravah ali v povezavi z njimi. V okvir te generične specifikacije sodijo eno- in večkanalni filtri v enem zaprtem prostoru. Predmet te specifikacije so tudi filtri, narejeni iz kapacitivnih elementov, pri katerih je induktivnost del konstrukcije filtra. Podobno so tudi filtri, narejeni iz induktivnih elementov, pri katerih je kapacitivnost del konstrukcije filtra, predmet te specifikacije. Proizvajalec mora navesti, ali je določen sestavni del narejen kot kondenzator, induktor ali filter. Filtri, ki so predmet te generične specifikacije, se nadalje delijo na tiste, za katere so varnostni preskusi primerni (npr. tisti, ki so povezani z omrežnim napajanjem), in tiste, za katere ti preskusi niso primerni. Ločena presečna specifikacija zajema pasivne filtre, za katere so varnostni preskusi primerni. Ta generična specifikacija vzpostavlja standardne izraze, nadzorne postopke in metode preskušanja, ki se uporabljajo za presečno in podrobno specifikacijo v okviru sistema IECQ-CECC za elektronske komponente.
