Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 8: E-cores
IEC 63093-8:2018 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of E-cores made of ferrite and the essential dimensions of coil formers to be used with them, as well the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to E-cores.The specifications contained in this document are useful in negotiations between ferrite core manufacturers and customers about surface irregularities. The use of derived standards, which give more detailed specifications of component parts while still permitting compliance with this standard, is discussed in Annex A.This edition includes the following significant technical changes with respect to IEC 62317-8:2006 and IEC 60424-3:2015:a. This document integrates IEC 62317-8:2006 and IEC 60424-3:2015;b. Table 4 ? Allowable areas of chips for E-cores, of IEC 60424-3:2015, has been moved to Annex C (informative) of this document.

Ferrite cores - Guidelines on the limits of surface irregularities - Part 3: ETD-cores, EER-cores, EC-cores and E-cores
IEC 60424-3:2015 gives guidelines on allowable limits of surface irregularities applicable to ETD-cores, EER-cores, EC-cores and E-cores in accordance with the relevant general specification. This standard is a specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. This edition includes the following significant technical changes with respect to the previous edition: a) addition of allowable areas of chips for EC-cores in Table 3, b) addition of crystallites in 4.5 and pores in 4.6.
