Scope

GB/T 13012-2008 is the English-translated version of 软磁材料直流磁性能的测量方法.

GB/T 13012-2008 — This standard specifies the method for use in a closed magnetic circuit or loop-like magnetic permeability soft magnetic material measuring DC magnetic properties.

Ring-like method is suitable for Sheet stacking ring-like, or whole solid ring-like ring and sintered samples.

This standard specifies the following two methods. a) an annular sample method, mainly applied to the magnetic field strength measured at 10kA/m or less; b) permeameter method for measuring the magnetic field strength in the range between (1 ~ 200) kA/m of. GB/T 13012-2008/IEC 60404-4:2000
