| Abstract: | According to Guide to the Evaluation and Expression of Uncertainty in Measurement, the uncertainty of mesurement of mercury in electrical and electronic equipments by cold atomic absorption spectrophotometric method was evaluated. The influence of uncertain factors were found out, and the components of uncertainty were calculated and evaluated. The results showed that the major sources of measurement uncertainty were the standard curve fitting and measurement repeatability, and the combined relative standard uncertainty was 1.61%. |
