BS EN IEC 63093-1:2020 pdf free.Ferrite cores — Guidelines on dimensions and the limits of surface irregularities,General specification.
BS EN IEC 63093-1 This part of IEC 63093 specifies the dimensions and allowable limits of surface irregularities of ferrite cores. It is intended that this document includes ferrite cores which are widely used and referenced in industry, either because they are included in national standards, or because they are seen 0 have broad-based use in industry. Where applicable, it is intended that the existing industrial name for each standard part appears with the part within this series.It is intended that this document excludes ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded.A ferrite core produced by only one or two suppliers can generally be considered a specialty part, and not suitable as a standard core within this series. A ferrite core produced by three or more competing manufacturers can generally be considered to be a candidate to be included in this series.IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard are reflected in the other type.This document is considered as a general specification useful in the dialogue between ferrite core suppliers and users about surface irregularities.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.IEC 60401-1, Terms and nomenclature for cores made of magnetically soft ferrites – Part 1:Terms used for physical irregularities.IEC 60401-2，Terms and nomenclature for cores made of magnetically soft ferrites 一Part 2: Reference of dimensions.
