Nonparametric Methods of Calculation of the Required Quantity of Test Objects and the Duration of Lifetime Tests

Formulas for calculating the required number of test objects and the duration of lifetime tests are proved depending on the estimate of the reduced mean lifetime lower confidence limit for a given confidence probability. The calculation formulas are valid for any time-to-failure law for a technical...

Zusammenfassung:	Formulas for calculating the required number of test objects and the duration of lifetime tests are proved depending on the estimate of the reduced mean lifetime lower confidence limit for a given confidence probability. The calculation formulas are valid for any time-to-failure law for a technical object. Examples of application of the lifetime test results are given.
