| Abstract: | The procedure of the uncertainty evaluation for the verification regulation of JJG 945--2010 M/cro Oxygen Ana- lyzers has been introducod in this paper. The working principle, standard of measurement and test procedure described in the verification regulation has also been introduced. The paper has proposed the evaluation procedure according to the foun- dation of the mathematical model of error for test, the source of the uncertainty, the combination of the standard uncertainty for metrology. This paper has also showed the uncertainty evaluation for the verification regulation of micro oxygen analyzer. The results could help and instruct the relative field engineer to evaluate uncertainty in verification regulation process. |
