There are many electrical equipment and components inside, such as intermediate relays, gas solenoid valves, water level detectors, etc. When selecting and testing and verifying, although manufacturers have their own life test reports, it is very important to choose a suitable component in your own factory according to the working conditions of your own design. At this time, you need a record of the number of tests and tests under different working conditions. When selecting by yourself, you can select electronic components based on the supplier's test requirements and the test content you need.

[0003] Especially after a product problem occurs, it is impossible to verify the lifespan immediately, and going to an external laboratory for verification is too inefficient.
