Annotation of standard text IEC 63093-2-ed.1.0 :
IEC 63093-2:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be used with them, as well as the effective parameter values to be used in calculations involving them. It also gives guidelines on the allowable limits of surface irregularities applicable to pot-cores in accordance with the relevant generic specification. The selection of core sizes and shapes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. The general considerations upon which the design of this range of cores is based are given in Annex A. This first edition cancels and replaces the first edition of IEC 62317-2 published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition of IEC 62317-2: a) addition of the limits of surface irregularities; b) Table 4 and Table 5 are updated in accordance with IEC 60205:2016. LIEC 63093-2:2020 specifie les dimensions importantes pour linterchangeabilite mecanique dune gamme preferentielle de circuits magnetiques en pots en ferrite, les limites dimensionnelles des corps de bobines a utiliser avec ces pots et les valeurs de parametres efficaces a utiliser dans les calculs les concernant. Elle donne egalement les lignes directrices relatives aux limites acceptables des irregularites de surface applicables aux circuits magnetiques en pots conformement a la specification generique correspondante. Le choix des tailles et formes de noyau pour le present document repose sur la philosophie consistant a introduire les tailles qui correspondent a des normes industrielles, soit dans une norme nationale soit par une utilisation a grande echelle dans le secteur industriel. Voir lIEC 62317-1 pour de plus amples informations relatives a ce principe de choix des tailles de noyau a inclure. Les considerations generales sur lesquelles sappuie la conception de cette gamme de noyaux sont donnees a lAnnexe A. Cette premiere edition annule et remplace la premiere edition de lIEC 62317-2 parue en 2010. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente de lIEC 62317-2: a) ajout des limites des irregularites de surface; b) le Tableau 4 et le Tableau 5 sont mis a jour conformement a lIEC 60205:2016.
