scope:

This part of 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 irregularuty, 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.
