Precision and Accuracy Study on Measurement of Soft Magnetic Properties Using DC Hysteresigraphs

We report on an interlaboratory study on the precision and accuracy of determining dc soft magnetic properties, under the auspices of ASTM Committee A06 on Magnetic Properties. For certain quantities, the significant differences in the between-laboratory reproducibility results for high-permeability materials indicate that there is a need for improvement in the equipment and software procedures of measurement systems
