IEC EN 63093-1 Ferrite Cores - Test for Dimensions and Limits of Surface Irregularities

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 63093-1 test. IEC EN 63093-1 specifies the dimensions and allowable limits of surface irregularities of ferrite cores.

This standard is intended to exclude ferrite cores, which are special cores of limited use. Also, special kernels that are only marginal variations relative to standard kernels are excluded. The IEC publishes this series of dimensional standards for ferrite core families as well as electrical standards for ferrite core families.

Changes made to ferrite cores listed in one standard type are reflected in the other type. This standard is considered a general specification that is useful in the dialogue about surface irregularities between ferrite core suppliers and users.

All surfaces of the core must be clean and free of loose ferrite particles or other foreign matter. This is more critical for mating surfaces that need to be in good contact with each other. Stains, discoloration, surface cracking or crystallization are acceptable if they do not affect the normal performance of the core.

The boundaries of surface irregularities are determined to control cosmetic appearance, not magnetic performance. Surface irregularities do not significantly affect core magnetic function, nor do they affect reliability. Reliability should be evaluated for wound magnets, not cores alone.
