This may be due to a requirement or for iwc purpose of assessing the behaviour in time of the failure rate or the failure intensity. We use cookies to make our website easier to use and to better understand your needs.

Ic are several reliability growth models available, the power law model being one of the most widely used. Part 1- Section One, Two and Three. Tests for the validity of the constant failure rate or constant failure intensity assumptions.

Describes procedures to estimate the parameters of the power law uec along with confidence intervals for failure intensity, and prediction intervals for the time to future idc along with a test of goodness of fit to data from repaired items. This part of IEC provides a general procedure for design of test cycles, where no applicable preferred test cycles can be found in IEC Some of the 50 IEC publications are:. These procedures are applicable whenever it is necessary to verify these assumptions.

This standard also addresses the collection, analysis and presentation of maintainability related data, which may be required during, and at the completion of, design and during item production and operation.
