 Organization: IEC Publication Date: 1 October 2016 Status: active Page Count: 48 ICS Code (Magnetic materials): 29.030
##### scope:

This part of IEC 60404 is intended to classify commercially available magnetic materials.

The term "magnetic materials" denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties.

In this document, the classification of magnetic materials is based upon the generally recognized existence of two main groups of products:

• soft magnetic materials (coercivity ≤1 000 A/m);

• hard magnetic materials (coercivity >1 000 A/m). Within these main groups, the classification when appropriate recognizes the following characteristics:

• the main alloying element and the metallurgical state and physical properties of the material;

• when possible and convenient, the relationship between these characteristics is identified.

A classification by specific areas of application cannot be applied to all materials because different materials can very often be used for the same application depending on the characteristics required.
