automobile environment reliability test

significance of detection reliability

the product can not just evaluate its functionality and performance is not good, but also integrated its various conditions, for example in the harsh environment, the reliability of its function and performance as well as maintenance, high and low cost. improve product reliability in extreme main surface, environmental testing occupies an important position, some say, there is no test environment, you can not correctly identify the quality of products to ensure product quality management. in the development, production and use of products runs through environmental testing, usually design, test and then test to improve production. the more truthful and accurate environmental testing, reliability of the product as possible. that applies to product research and test, type test, inspection tests, acceptance tests and safety trials.

purpose of environmental reliability testing

in the development phase of the trial to expose all aspects of product defects, product reliability evaluation of the situation reaches a predetermined index;

production stage to monitoring of the production process to provide information;

styling products for the reliability identification or acceptance;

exposure and analysis of product failure regularity under different environmental conditions and stress and failure modes and failure mechanisms related;

to improve product reliability, development and improvement of the reliability of the test program, the user selected to provide a basis for using the product.
