采用直接评定法评定了带肋钢筋拉伸性能、金属材料维氏硬度检测结果的测量不确定度，用综合评定法评定了金属材料夏比缺口冲击试验、洛氏硬度检测结果的不确定度。结果表明，综合评定法在这些典型实例中解决了金属材料理化检测结果测量不确定度评定的某些难点。

It was proposed in this paper that various test parameters for materials should be adopted for different evaluation methods in order to raise the reliability of evaluation for the measurement uncertainty. The immediate evaluation method was used to evaluate the measurement uncertainty of test results for the tensile property of the hot rolled ribbed steel bars and Vicker hardness of metallic materials, while the synthetic evaluation method was applied for evaluating the measurement uncertainty of testing results for impact test and Rockwell hardness of metallic materials. These typical illustrations showed that some diffculties in the evaluation of measurement uncertainty were solved by synthetic evaluation method for physical testing and chemical analysis of metallic materials.
