Hi,

Questions often arise in the metrological community such as:

1. Is it necessary for the unknown systematic error to be studied or not?
2. If so, what are the properties that characterize the unknown systematic error?
3. According with what matter the unknown systematic error is incorporated in the final result of measurement?
4. Does knowledge about the non-detectable systematic error contribute to traceability in metrology?
5. Is there any alternative methodology for type A uncertainty estimation?
6. Is the term “measurement uncertainty” the right one or is it the term “measurement uncertainties”?
7. Is possible for there to exist an estimation of an upper limit of the magnitude of the dispersion parameter of population sigma from the dispersion parameter of the sample s or not?
8. Which are the requirements that must be fulfilled for the transition from the Localization to the Determination of the measurand’s true value?
9. What is the goal of the measurement?

In the paper:

“The unknown systematic error”
( http://www.uncertainty.gr/error.pdf )

clear answers will be given to the above questions.

Thanks!
