抗拉强度测量不确定度评定

Evaluation of Measurement Uncertainty for Tensile Strength

探讨了抗拉强度测量不确定度的分析方法,主要从试样截面积测量和拉力测量两个方面分析了测量不确定度来源,以及测量不确定度在试验结果中的表示方法。说明了不确定度在试验结果表达中的重要意义和对产品质量判定的重要性,为以后在类似试验中对试验结果不确定度分析提供借鉴。

The analysis method of measurement uncertainty for tensile strength was discussed, the source of measurement uncertainty, including sample cross section and pull , and expression method were analyzed. It showed that was important in measurement result expression and product quality, and it was referential in measurement uncertainty of similarity test.
