Background. The actual problem in measuring residual resource takes a leading position in reliability theory. However, the calculation of the resource based on the results of the forced tests on the refusal of the unrecoverable objects researched in not sufficiently.
Materials and methods. For non-restorable by forced tests on the refusal of technical objects withdrawn non-parametric formulas for calculating resource. A theorem for estimating the average resource for equitable distribution law. It is shown that the resulting statement is true when evaluating the secondary resource for other parametric laws that, for example, for exponential distribution law of tailormade developments there are only two values of gammainterest resources the arithmetic mean is equal to the average resource. Represented by a graphical interpretation of gamma-interest resources, statistical (dot) evaluation of gamma per cent resource, as well as the lower limit of the trust.
Conclusions. Proposed non-parametric calculation formula and resource estimates for non-restorable by forced endurance tests on failure of technical objects.
