适用范围:This part of IEC 60404 specifies 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. 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.
