BS-IEC-60404-1-2000 pdf free download – Magnetic materials Ð Part 1: Classification
1General
1.1Scope and object
This standard is intended to classify commercially available magnetic materials.
The term “magnetic materials” denotes substances where the application requires theexistence of ferromagnetic or ferrimagnetic properties.
In this standard, the classification of magnetic materials is based upon the generallyrecognized existence of two main groups of products:
– soft magnetic materials (coercivity ≤1 000 Am);- hard magnetic materials (coercivity >1 000 A/m).
within these main groups，the classification when appropriate recognizes the followingcharacteristics:
– the main alloying element and the metallurgical state and physical properties of the
material;
when possible and convenient,the relationship between these characteristics isidentified.
A classification by specific areas of application cannot be applied to all materials becausedifferent materials can very often be used for the same application depending on thecharacteristics required.
