The application of robust statistical methods to assess the precision (uncertainty) of the results of interlaboratory comparison tests is presented. The case, when these results may include outliers is considered. An usual rejection of such data reduces the reliability of evaluation, especially for small samples. The robust methods take into consideration all samples data including outliers. The use of the robust method Algorithm S is provided for estimating the precision of some measuring method tested in comparative studies in the group of accredited laboratories. Result obtained for simulated example is very close to the case with rejection outliers, but more reliable.
