- Abstract:
- A new approach to upgrading the type A uncertainty evaluation by investigation the trend and periodical systematic components in the regularly in time performed observations is presented in the paper. This is a part of best practice, which authors recommend as upgrading the routine procedures in uncertainty evaluation according to ISO GUM recommendation. The cleaning of raw data set by elimination the systematic components and the influence of these cleanings on standard uncertainty is presented and disused. Two numerical examples are discussed.
