Reliability test is to evaluate and important technical means to improve the reliability of the product, and it involves testing scheme of the records of r&d, test process, test equipment, the establishment of the fault analysis technology, etc.
Purpose of reliability test:
Reliability test is an experiment to analyze and evaluate the reliability of products.Through the analysis of test results, not only can determine product reliability index, and can analyze the product failure, find out the weak links, and adopt corresponding countermeasures, achieve the goal of improving product reliability.Therefore, reliability test is one of the important means and contents to study product reliability.
Characteristics of reliability test:
Reliability test with the routine test of the product is different, the purpose of the routine test, only to ensure products factory acceptance when the index of its parameters and physical and mechanical properties conform to the factory, without the need to determine the failure rate of products within the prescribed time, so can't offer any guarantee the reliability of the product.
The reliability test provides assurance that the product meets certain reliability indicators in the time of use.At the same time, reliability test is the basis of product reliability prediction and verification.
In addition, in the processing of experimental data, the normal test is only the performance test, so the data processing is relatively simple.The reliability test is based on the reliability of a batch of products, so the jianyu testing network recommends strict statistical methods to make more reliable conclusions.
Since the purpose and requirements of the test are different, the test methods are not the same.Therefore, it is important to distinguish between the two different concepts of routine test and reliability test.
