5.2 Typical Measured Parameters

Parameter	Best Measurement Uncertainty (k=2)	Best Measurement Repeatability
Magnetostriction Coefficient *λ_p-p*	5%+0.05 μm/m	2%+0.02 μm/m
Magnetic Field Strength H_m	0.5%	0.2%
Magnetic Flux Density *B_m*	0.5%	0.2%

Specific Total Loss Ps	1.0%	0.3%

Test Conditions:

H, B, J at a measurement frequency of 50 Hz / 60 Hz, under stress-free conditions
For grain-oriented silicon steel: 1.7 T; for non-oriented silicon steel: 1.5 T, under stress-free conditions
Regarding accuracy of measured values: Depending on the method and position of the specimen in the measurement frame, a deviation of 1% to 2% may occur.
Regarding repeatability of measured values: For the same specimen, without considering its temperature characteristics, after placing the specimen in the specified position and keeping it stationary, repeated measurements are performed. The resulting (repeatability data) is regarded as the repeatability of the specimen and is related to the performance of the specimen under test.
Repeatability = the larger of the two values calculated as:

( |maximum value – average value| ) / average value

( |minimum value – average value| ) / average value
