This part of IEC 60401 provides a nomenclature of the most frequent surface, bulk and shape
irregularities relevant to cores made of soft ferrites (magnetic oxides). Most irregularities are
graphically exemplified as visual aids. A general recommendation is also given in Annex A 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 document
can also be useful as a...
