| Abstract: | The principle of measurement uncertainty and its applications in physical testing and chemical analysis was introduced in this lecture. The definitions, classification, steps and method of evaluation, report and expression, significant places of number etc. for measurement uncertainty were also discussed in the lecture. Moreover, the measurement uncertainty of tensile testing results of metallic materials were evaluated in detail, which was provided as a typical illustration in the scope of physical testing and chemical analysis. |
