BS EN 60404-4+A2 is a British standard on methods of measuring the d.c. magnetic properties. BS EN 60404-4+A2 is part of the IEC 60404 series on magnetic materials. BS EN 60404-4+A2 is a guide on the methods of measuring the d.c. magnetic properties of magnetically soft materials iron and steel in a closed magnetic circuit using either the ring or the permeameter methods.
BS EN 60404-4+A2 outlines two methods:
Note: The measurement of coercivity in an open magnetic circuit is specified in IEC 60404-7.2.
BS EN 60404-4+A2 magnetic materials is useful for:
Magnets protects the equipment from the damages and also separates heavy metals from the residue. BS EN 60404-4+A2 guidelines provide an outline on the measurement of the magnetic field strength and flux density. Using BS EN 60404-4+A2 guidance can increase the credibility of the equipment and safety as well.
