8、initions For the purposes of the present document, the terms and definitions given in the R - the value of the measurement uncertainty for the measurement of each parameter shall be included in the test report; - the recorded value of the measurement uncertainty shall be, for each measurement, equal
9、 to or lower than the figures in table 1. For the test methods, according to the present document, the measurement uncertainty figures shall be calculated in accordance with TR 100 028 3 and shall correspond to an expansion factor (coverage factor) k = 1,96 or k = 2 (which provide confidence levels
10、of respectively 95 % and 95,45 % in the case where the distributions characterizing the actual measurement uncertainties are normal (Gaussian). Table 1 is based on such expansion factors.
