Scope
This part of GB/T 11441 specifies the minimum magnetic permeability requirements for laminations prepared from silicon-iron and nickel-iron alloys of types C2, E1, E3, and E4 defined by GB/T 21219—2007. These requirements are more applicable to laminations listed in GB/T 11441—1989. The performance specified in this part applies to laminations tested under sinusoidal magnetic flux and a frequency of 50 Hz or 60 Hz, and which have undergone sufficient heat treatment.
