Soft ferrite material classification (IEC 61332:2016); German version EN 61332:2017
This document specifies classification rules for soft ferrite materials used in inductive components (inductors and transformers) fulfilling the requirements of the electronic industries. This document addresses the following issues for ferrite suppliers and users: cross-reference between materials from multiple suppliers; assistance to customers in understanding the published technical data in catalogues when comparing multiple suppliers; guidance to customers in selecting the most applicable material for each application; setting of nomenclature for IEC standards relating to ferrite; establishing uniform benchmarks for suppliers for performance in new development of materials. The numerical values given in this document are typical values of the parameters (properties) of the related materials. Direct translation from the material specification into the core specification is not always easy or possible. Every detailed material and core specification should be agreed upon between the user and the manufacturer.

Dimensions for magnetic oxide cores intended for use in power supplies(EC-cores)
This International Standard describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring methods are intended for the investigation of materials, generally referred to as ferrites, for application at microwave frequencies. Single crystals and thin films generally fall outside the scope of this standard.
Gyromagnetic materials intended for application at microwave frequencies - Measuring methods for properties
This part of IEC 62317 specifies the dimensions that are of inportance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the baes outlines of the cores. It also specifies the test conditions and clamping forces to be used for inductance meaurement. The general considerations that the design of this range of cores is based upon are given in Annex A.

The document specifies the marking on U and E ferrite cores.
Marking on U and E ferrite cores (IEC 61333:1996); German version EN 61333:1998
Dimensions of square cores (RM-cores) made of magnetic oxides and associated parts.
This part of IEC 60424 gives a guidance on allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification. This standard should be considered as a sectional specification useful in the dialogue between ferrite core manufacturers and customers about surface irregularities.
