Test Conditions:

• H, B and J are measured at a measuring frequency of 50 Hz / 60 Hz and under no stress conditions.

• Oriented silicon steel: 1.7 T, non-oriented silicon steel: 1.5 T under no stress conditions

• The accuracy of the measurement value: There will be a deviation of 1 to 2% depending on the way and position of the sample loaded in the measurement frame.

• The repeatability of measurement values: If the same sample is placed in a designated position and kept in a designated position without moving and measured repeatedly (obtaining repeated data) without considering the temperature characteristics of the sample, it is regarded as the repeatability of the sample. And related to the performance of the sample being tested.

• Repeatability = Ι maximum value - average value Ι ÷ average value, Ι minimum value - average value Ι ÷ average value, take the bigger value of the two.
