45、recorded value of the measurement uncertainty shall be, for each measurement, equal 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 and shall correspond to an expansion factor (coverage factor)

46、k = 1,96 or k = 2 (which provide confidence levels of respectively 95 % and 95,45 % in the case where the distributions characterizing the actual measurement uncertainties are normal (Gaussian). Principles for the calculation of measurement uncertainty are contained in ETSI TR 100 028 i.3, in partic

47、ular in annex D of the ETSI TR 100 028-2 i.2. Table 1 is based on such expansion factors.
