MAGNETIC PROPERTIES OF OIML SHAPED WEIGHTS
Abstract
The work presents an improved approach to the determination of magnetic properties of weights, which have a shape according to OIML R111. The main stress is laid on a measurement of the volume magnetic susceptibility and an evaluation of its uncertainty. The method is presented, how the volume magnetic susceptibility of the OIML weight can be determined taking into account an actual shape of the weight instead of using only an approximation of its shape with "outer" and "inner" cylinders. Monte Carlo simulation was used to evaluate the measurement uncertainty. The susceptibility of 1 kg weight was calculated by the method of "outer" and "inner" cylinders and the method presented in the article. Results of both methods are compared and discussed.
