Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 4: RM-cores
IEC 63093-4:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to RM-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 a national standard, or by broad-based use in industry.This document is a specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities.This first edition cancels and replaces the first edition of IEC 62317-4 published in 2005 and the second edition of IEC 60424-2 published in 2015. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to IEC 62317-4:2005 and IEC 60424-2:2015:a) IEC 63093-4 integrates the contents of IEC 62317-4:2005 and IEC 60424-2:2015;b) IEC 60424-2:2015, Table 2, has been included in Annex C as Table C.1.

Ferrite cores - Dimensions - Part 4: RM-cores and associated parts
IEC 62317-4:2005 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also specifies the test conditions and clamping forces to be used for inductance measurement. This international standard cancels and replaces the second edition of IEC 60431 published in 1983, its amendment 1 (1995), and its amendment 2 (1996). This international standard constitutes a technical revision of IEC 60431. The contents of the corrigendum of July 2016 have been included in this copy.

Ferrite cores - Guidelines on the limits of surface irregularities - Part 2: RM-cores
IEC 60424-2:2015 provides guidelines on the allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification. This standard should be considered as a sectional specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. Normative reference. This edition includes the following significant technical changes with respect to the previous edition: - addition of crystallites in 3.6 and of pores in 3.7.
