| Abstract: | The method for evaluation ofuncertainty on measurement results for tensile test was modified in GB/T 228. 1-2010 standard. Basing on testing the tensile capability of steel plate, the uncertainty of measurement results for proof strength of total elongation performance and tensile strength performance was evaluated, the source of uncertainty was analyzed, the outliers of the measurement results was rejected, a feasible method of evaluation of uncertainty on measurement results for tensile test was provided, and several problems raised in the process of evaluation were discussed. |
