CCT Working Group 3 stated it well:
“Corrections are applied where bias (systematic error) is known, including in most cases where the correction is less than the uncertainty. This is done to maximise the information retained in reported measurement results and to prevent the accumulation of significant bias.” [CCT/08-19, “Uncertainties in the realisation of the SPRT subranges of the ITS-90″]

I have a question. In the computation of the uncertainty should also be considered the measurement errors of the dew point and air temperature.
For example, suppose that the error of the dew point is 0.1 ° C at 10% rh, and to immagine and a coverage factor k = 1.732, then u(k=1)=0.0577, senstivity=0.010 and u(rh) for this element =0,000577.
The same reasoning for the error related to air temperature.
Is it correct.
Thanks in advance for your time.
