Bibliography

IEC 60424-1:2015 gives guidelines on the allowable limits of surface irregularities of ferrite cores. This standard should be considered as a general specification useful in the dialogue between ferrite core manufacturers and customers about surface irregularities. This edition includes the following significant technical changes with respect to the previous edition:- addition of pores in 3.5 and crystallites in 3.6.
