Annotation of standard text IEC 63093-14-ed.1.0 :

IEC 63093-14:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EFD-cores, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. It also gives guidance on the allowable limits of surface irregularities applicable to EFD-cores in accordance with the relevant generic specification. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in national standards, or by broad-based use in industry. This document is a specification useful in the negotiation between ferrite core manufacturers and users about surface irregularities. This first edition cancels and replaces the first edition of IEC 62317-14 published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 62317-14:2008:

  1. guidelines on the limits of surface irregularities of EFD-cores were added.
L’IEC 63093-14:2019 specifie les dimensions qui presentent une importance pour linterchangeabilite mecanique dune plage preferentielle de noyaux EFD, les dimensions essentielles des supports de bobine a utiliser avec les noyaux EFD, ainsi que les valeurs des parametres effectifs a utiliser dans les calculs qui impliquent ces noyaux. Elle donne egalement des recommandations relatives aux limites admissibles des irregularites de surface applicables aux noyaux EFD conformement a la specification generique correspondante. Le choix des tailles des noyaux pour le present document est fonde sur la philosophie consistant a introduire les tailles qui correspondent a des normes industrielles, soit par inclusion dans des normes nationales, soit par utilisation a grande echelle dans l’industrie. Le present document est une specification utile a la negociation entre les fabricants et les utilisateurs de noyaux ferrites sur les irregularites de surface. Cette premiere edition annule et remplace la premiere edition de l’IEC 62317-14 parue en 2008. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’IEC 62317-14:2008:
  1. ajout de lignes directrices relatives aux limites des irregularites de surface des noyaux EFD.
