What is an accelerated life test?

Accelerated life test is a method for stress testing of consumer goods such as electronics. The test usually consists of five independent phases: cold step, heat step, rapid temperature cycling, graded vibrations and combined environmental stress. Although the item may never experience extremes that produce an accelerated life test, studies have shown that if an item is prone to some extreme stress in the short term, it will be prone to determining the same voltage in smaller degrees in the long term. The thermal step tests the functionality of the device at high temperatures. This step is often combined with a moisture test to see if atmospheric water affects the device. These acceleratuses ED Life Test Systems create changes to at least 113 ° F (45 ° C) per minute. The temperature varies quickly between two extremes to see if it has any effect on the device. The aim of this test is to show how well the device will last during transport, as well as during heavy management. Combined phase onThe five -voltage for the environment throws it all together and tests devices with vibrations at extreme temperatures.

Before starting any testing, the device parameters are usually calculated. For example, if the team determines that certain devices do not have to receive high rating against cold extremes, then they usually notice that cold failure does not necessarily mean device failure. The same may apply to extreme temperature conditions.

Generally, the devices are going to the thhruby test of accelerated life many times before they get to the market. Individual components usually pass through the test cycle until they change all. Then the assembled device is usually tested. If the parts are not good, they are usually sent back to the design team, which could then rework the weak component.

A accelerated life test can also use companies to determine the warranty contract. It is also used during the prickby the device to make sure the product is consistent. If there is an inflow of complaints about inferior products, the company can order an intensive test of accelerated life to find a weak point of the device as quickly as possible.
