Notes:
a. Testing reference GB/T3655-2008.
b. Test one half of the test sample respectively on the horizontal and vertical directions.
c. As for AR product series of the stress relieving, annealing and high-efficiency non-oriented electrical steel, the magnetism testing is only applicable to the state where the test sample, after two hours of stress relief and annealing, is under the temperature of 750℃.
d. P15/50refers to the core loss of a test sample, whose unit is kg, at the maximum magnetic induction intensity of 1.5T and the frequency of 50Hz.
P10/400refers to the core loss of a test sample, whose unit is kg, at the maximum magnetic induction intensity of 1.0T and the frequency of 400Hz.
e. B50refers to the magnetic induction intensity when the magnetic field intensity is 5000A/m.
