摘　　要：分析了拉伸试验中抗拉强度Rm 的影响因素 ,对测量不确定度的主要分量进行量化 ,评定了Rm 的相对测量不确定度 ,作为生产检验中评定测量不确定度的尝试 。The factors affecting the tensile strength R m  in the tensile test are discussed and the extent of uncertainty in the measurement quantitatively analyzed. And the uncertainty of relative measurement on the tensile strength R m  is also assessed in a trial to evaluate and determine the uncertainty of measurement in the actual quality check and examination in the production so as to provide customers with the extent of uncertainty of measurement in reference to the results of the properties measurement of steel products.
