布氏硬度试验中测量不确定度的评定

Evaluation About Uncertainty of the Measurement During Brinell Hardness Test

介绍了测量硬度不确定度的原理 ,并以金属材料布氏硬度试验结果的不确定度的评定作为不确定度在理化检验中应用的一个实例。

The principle of measuring hardness uncertainty was introduced.Then the measurement uncertainty of Brinell hardness test results for metal materials was evaluated in detail,which was provided as a typical illustration in the scope of physical test and chemical analysis.
