overloading the article, and other problems related with the development of programs of accelerated equivalent tests were not considered in the given paper. We must indicate only that the regimes for such tests are selected on the basis of the equality of the factors of safety (life) of the main components determining the operational capability of the article during operation according to a program taken as the reference and according to a program of accelerated equivalent tests. In this case one uses the known time relationships between the loads and operational capability of the structural components (usually the cumulative damage hypothesis). It is easy to show that sufficiently founded solutions can be obtained in this case only for a small number of structural elements. At the same time there is a pressing need for an objective evaluation of the operational capability also of those structural components for which the equivalence conditions are not fulfilled. Only in this case can accelerated equivalent tests be applied to a comprehensive evaluation of the operational capability and reliability of a structure. Ultimately this amounts to an evaluation of the reliability indices of the article, i.e., to finding the relation o~ = F @~,
