This part of IEC 60401 provides a nomenclature of the most frequent surface, bulk, and shape
irregularities relevant to cores made of ferrites (magnetic oxides). Most irregularities are
graphically exemplified as visual aids. A general recommendation is also given for a
consistent scheme for specifying the exact location of the irregularity, combining a general
name for the location with more detailed qualifiers of the specified location. This standard can
also be useful as a terminology reference when preparing technical documentation,
irregularity inspection specifications, etc.
