Annotation of standard text IEC 62391-1-ed.3.0 :

IEC 62391-1:2022 applies to fixed electric double-layer capacitors (hereafter referred to as capacitors) mainly used in DC circuits of electric and electronic equipment. This part of IEC 62391 establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications of electronic components for quality assessment or any other purpose. This edition includes the following significant technical changes with respect to the previous edition:

1. The document has been completely restructured to comply with the ISO/IEC Directives, Part 2; a new technical categorization of test methods has been introduced and the test methods have been reorganized according to these new categories; tables, figures and references have been revised accordingly.
2. Calculation formula of charging/discharging efficiency in Annex D were divided into two cases: "Calculation assuming full charge and discharge" and "Calculation assuming incomplete charging and discharging due to internal resistance".

L’IEC 62391-1:2022 s’applique aux condensateurs electriques fixes a double couche (appeles ci-apres condensateurs) principalement utilises dans des circuits a courant continu d’equipements electriques et electroniques. La presente partie de l’IEC 62391 definit les termes normalises, les procedures de controle et les methodes d’essai utilises dans les specifications intermediaires et particulieres des composants electroniques dans le cadre de l’assurance de la qualite, ainsi qu’a d’autres fins. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente:

1. Le present document a ete integralement restructure pour satisfaire aux Directives ISO/IEC, Partie 2. De nouvelles categories techniques des methodes d’essai ont ete introduites, les methodes d’essai ayant ete reorganisees en fonction de ces nouvelles categories. Les tableaux, figures et references ont ete revises en consequence.
2. Les formules de calcul de l’efficacite de charge/decharge de l’Annexe D ont ete divisees en deux: "Calcul prenant pour hypothese la pleine charge et la pleine decharge" et "Calcul prenant pour hypothese une charge et une decharge incompletes, dues a la resistance interne".
