Measurement uncertainty analysis for bulk current injection calibration process

In this article, the setup and calibration process of the BCI test according to ISO 11452-4 and a general evaluation and calculation of the total measurement uncertainty is presented. This sample measurement uncertainty calculations can be used as the measurement uncertainty calculations, which are absent in ISO 11452 standards. After the introduction into the measurement uncertainty calculation, the calibration process is critically examined on many sources of measurement uncertainties and mismatches inside the setup, which have significant impact on the calibration and also on the testing process. Additionally, new sources of uncertainty are evaluated in this paper, which can have a high impact on the calibration and testing process. This sample measurement uncertainty calculations can be used as the measurement uncertainty calculations, which are absent in ISO 11452 standards. With all detected sources of uncertainties, the measurement uncertainty calculation models can be used for other international standards with similar calibration and test processes, which are used for testing devices for different fields of application, and by calibration and testing laboratories, to improve the reproducibility of the calibration and testing process.
