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.
