Fixed capacitors for use in electronic equipment - Part 14: Sectional specification - Fixed capacitors for electromagnetic interference suppression and connection to the supply mains
IEC 60384-14:2023 applies to capacitors and resistor-capacitor combinations intended to be connected to AC mains or other supply with a nominal voltage not exceeding 1 000 V AC (RMS), and with a nominal frequency not exceeding 100 Hz. This document includes also additional specific conditions and requirements for the connection to DC supplies with a rated voltage not exceeding 1 500 V DC. The principal object of this part of IEC 60384 is to prescribe preferred ratings and characteristics and to select, from IEC 60384-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of equal or higher performance level; lower performance levels are not permitted. This document also provides a schedule of safety tests to be used by national testing stations in countries where approval by such stations is required. The overvoltage categories in combination with the AC mains voltages for the capacitors classified in this document are to be taken from IEC 60664-1. This edition includes the following significant technical changes with respect to the previous edition:
in damp heat steady state test, all capacitor types are tested both with and without rated voltage; the number of test pieces has been increased;
tangent of loss angle is added In Group 0 tests, in safety tests only;
qualification approval based on safety and performance tests has been removed from the main text to a normative annex;
the range of rated voltages is given instead of exact rated voltage values;
normative annex for description of capacitor styles and of creepage/clearance distance measurement has been added;
the importance of mechanical failures (cracks) in component encapsulation as a safety feature is highlighted in handling instructions and requirements after all relevant tests.
Condensateurs fixes utilisés dans les équipements électroniques - Partie 14: Spécification intermédiaire - Condensateurs fixes pour la suppression des interférences électromagnétiques et la connexion au réseau d’alimentation
L’IEC 60384-14:2023 s’applique aux condensateurs et aux combinaisons condensateur/résistance destinés à être connectés à un réseau d’alimentation en courant alternatif ou à une autre alimentation dont la tension nominale ne dépasse pas 1 000 V c.a. (efficace) et dont la fréquence nominale ne dépasse pas 100 Hz. Le présent document inclut également des conditions et des exigences spécifiques supplémentaires pour la connexion aux alimentations en courant continu avec une tension assignée ne dépassant pas 1 500 V en courant continu. La présente partie de l’IEC 60384 a pour principal objet de prescrire les valeurs assignées et caractéristiques préférentielles, de sélectionner, en se référant à l’IEC 60384-1, les procédures d’évaluation de la qualité appropriées, les essais et les méthodes de mesure et de donner les exigences de performances générales pour ce type de condensateur. Les sévérités et les exigences d’essai indiquées dans les spécifications particulières se rapportant à cette spécification intermédiaire présentent des niveaux de performances supérieurs ou égaux. Les niveaux de performance inférieurs ne sont pas autorisés. Le présent document fournit un programme d’essais de sécurité à utiliser par les stations d’essai nationales dans les pays qui exigent une approbation par de telles stations. Les catégories de surtension associées aux tensions d’alimentation alternatives pour les condensateurs classifiés dans le présent document doivent être issues de l’IEC 60664-1. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
dans l’essai continu de chaleur humide, tous les types de condensateurs sont soumis à essai à la fois avec et sans tension assignée. Le nombre d’éprouvettes a été augmenté;
la tangente de l’angle de perte est ajoutée dans les essais du Groupe 0, dans les essais de sécurité uniquement;
l’homologation basée sur les essais de sécurité et de performance a été supprimée du corps du texte pour en faire une annexe normative;
la plage de tensions assignées est donnée au lieu des valeurs exactes de tension assignée;
une annexe normative de description des modèles de condensateurs et de la mesure des lignes de fuite et des distances d’isolement a été ajoutée;
l’importance des défaillances mécaniques (fissures) dans l’encapsulation des composants en tant que caractéristique de sécurité est mise en évidence dans les instructions de manipulation et les exigences après tous les essais pertinents.
