The invention discloses a creep data screening method based on statistical test and state inspection, which comprises the following steps: step 1, recording sample state parameters, and carrying out a creep experiment to obtain actually measured creep data; step 2, substituting the creep data into the creep constitutive model, fitting to obtain a creep constitutive equation in a corresponding form, and fitting to obtain a predicted value; step 3, calculating a function difference value [delta]f(x) between the actually measured creep data and a predicted value, and checking a statistical distribution rule of the [delta]f(x); step 4, according to a set saliency level alpha, searching for an outlier in the [delta]f(x) data, marking the actually measured creep data corresponding to the outlier as invalid actually measured creep data, and removing the invalid actually measured creep data; and step 5, repeating the steps 2-4 until all the remaining actually measured creep data do not have the outliers any more. According to the method, the flexibility of data screening is improved, the difficulty of subsequent material creep performance calculation and evaluation work is reduced, and the reliability and accuracy of creep performance prediction are improved.
