Abstract��In order to evaluate uncertainty of testing tensile strength at elevated temperature, five piec of proportional specimens of ��5 mm were pickout from the material of GH4033. The math model to calculate uncertainty is established by math formula and considering all different factors influencing testing results, in order to determine the different source of uncertainty. The combined uncertainty as well as expanded uncertainty of tensile strength is figured out.
