Gives the dimensions for mechanical interchangeability for a preferred range of square cores made of magnetic oxides, the dimensional limits for wound coil formers used with these cores and the locations of their terminal pins on a 2.54 mm printed wiring grid in relation to the base outlines of the cores. Describes the main parameters of a range of standard inductance measuring coils used for test purposes.
