The conducted investigations aimed to elaborate the method of marking diagnostic tolerances of the exhaust temperature of a gas turbine observed during engine's start-up process. The diagnostic tolerances were determined by means of statistical inference by creating the hypothesis about a normal distribution of the start-up exhaust temperature's dispersion in the initial operation moment, which was subsequently verified applying a non-parametric statistical test χ2 of the compliance between the empirical and assumed normal distribution. A satisfactory convergence of the compared distributions was obtained as the result of testing the created hypothesis, which represented the basis to accept the three-sigma borders of diagnostic tolerances for the considered engine's control parameter.
