The value of the resource indicator of the object according to the test results during time t is limited to this duration [1−6]: the shorter the test time t, the lower the value of the resource indicator, and, conversely, the longer the duration t, the greater the value of the resource indicator. Obviously, in the first case, a resource stock is observed with respect to the second case.

Goal was to determine the resource reserve coefficient of the object and derive formulas for its calculation and assessment to find the prolonged life of the object beyond the assigned levels.

Residual life supply coefficient has been determined for non-restorable-after-failure objects. Calculation formulae are proved for this indicator, its evaluations and limit values are obtained. The use of these results is exemplified for the evaluations of residual life indicators.

The coefficient of the resource reserve of an unrecoverable object is determined. The calculation formulas, estimates, and limit values of the introduced indicator are rigorously mathematically justified. Examples of the use of the results obtained in the tasks of extending the life of objects are given.
