The result of the measurement should include the uncertainty, which characterizes the dispersion of the values that could reasonably be attributed to the measured. The results value is consequently determined using statistical evaluation of measurement (type A evaluations of uncertainty) and using estimate or experťs data (type B evaluations of uncertainty). The resulťs value of uncertainty is mostly presented as coveraged, which was assessed by fusing of uncertainty of A type and B type and multiplying with coverage factor expanding probability interval (mostly on value of 0.95). Expanded uncertainty must be presented with regarding on practical purpose of the result of measurement, consistently with valid standards.
