Abstract: | Accelerated life testing of products and components is used to get information quickly on specific lives, life distributions, failure rates, mean lives and reliabilities. Accelerated testing of manometers is achieved by subjecting the test units to application and operation pressure levels that are more severe than normal or use pressure levels, in order to shorten their lives or their times to failure. If the results can be extrapolated to the use pressure levels, they yield estimates of the lives and reliabilities under use pressure. |
