The reliability test is a test to verify the possible failure of the product due to changes in various use environments or use states during the process of storage, transportation and use after the completion of manufacture , so as to test the degree of reliability of the product against these changes. Reliability test is usually a group of tests, including aging test or life test, environmental test, such as anti-vibration or bump test, ultraviolet resistance test, three-proof test, environmental test, etc. Through reliability tests, various information related to product performance can be obtained, thereby providing important references for improving product design and production technology, strengthening quality management and process control, and evaluating product levels .
For different products, in order to achieve different purposes, different reliability . There are many classification methods for reliability tests: if it is divided by environmental conditions, it can be divided into simulation tests and field tests under various stress conditions ;
Divided by test items, it can be divided into environmental test, life test, accelerated test and various special tests;
If divided according to the purpose of the test, it can be divided into screening test, identification test and acceptance test;
If divided according to the nature of the test, it can also be divided into two .
