Provides procedures for estimating the parameters of the most widely used model for describing the reliability of repaired items and for testing its goodness-of-fit to data

This International Standard specifies procedures to estimate the parameters of the power law model, to provide confidence intervals for the failure intensity, to provide prediction intervals for the times to future failures, and to test the goodness-of-fit of the power law model to data from repaired items.
