Accelerated Life Testing (ALT)

Accelerated Life Testing (ALT) is a testing methodology that involves subjecting a product to various stresses above those that would be seen during normal operation in an effort to induce failures. Some examples of stresses that may be used in ALT include temperature, vibration, voltage, and humidity.  ALT analysis uses life data obtained through accelerated life testing to predict product reliability at normal stress levels.

ALT is used in order to test and assess product reliability in minimal time. While test beds can be set up to cycle a product through normal use situations, it may take a long time to obtain a useful set of failure data for analysis. Or, your product may have a very high reliability requirement and must be viable for a long period of time, longer than can be tested for using normal conditions. Or, perhaps you are seeing that your product is failing over a long period of use, and you need to determine a remedy. By effectively using accelerated life testing, product reliability and performance can be predicted based on the data obtained.

Relyence ALT provides a framework for you to manage and perform accelerated life testing analysis.
