适用范围：This part of IEC 60404 specifies the methods of measuring the d.c. magnetic properties of magnetically soft materials in a closed magnetic circuit using either the ring or the permea-meter methods. The ring method is suitable for use with laminated or solid ring specimens as well as ring specimens produced by sintering.Two methods are used:a) the ring method, particularly for magnetic field strengths of up to 10 kA/m;b) the permeameter method for magnetic field strengths in the range 1 kA/m to 200 kA/m. NOTE The measurement of coercivity in an open magnetic circuit is specified in IEC 60404-7.
