NEN-EN-IEC 63093-2 specifies the dimensions that are of importance for mechanicalinterchangeability for a preferred range of pot-cores made of ferrite, and the dimensionallimits for coil formers to be used with them, as well as the effective parameter values to beused in calculations involving them. It also gives guidelines on the allowable limits of surfaceirregularities 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 ofincluding 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 philosophyof selecting core sizes to be included.The general considerations upon which the design of this range of cores is based are given inAnnex A.
