The bias component in measurement uncertainty - Eurachem
3.2.7. In carrying out studies of overall bias, it is important that the reference materials and values are relevant to the materials under routine test. 5.4 …method used is empirical. It is not meaningful to consider correction for bias intrinsic to the method, since the measurand is defined by the method used. 6.6. In practice, it is more ...
