| Abstract: |
| Objective To straighten out data processing method of step-up stress accelerated life test and promote extensive application of step-up stress accelerated life test. Methods The life expectancy of the product under normal stress level was estimated according to estimation of product life distribution, conversion of test data, establishment of regression model, estimation of model parameter and other steps. Results The data processing method of step-up stress accelerated life test was applied according to test data of a product. Conclusion Steps for processing method of test data are established and suggestions on design of step-up stress accelerated life test are proposed. |
