<br/><br/> Sample of such materials is selected and then subjected to more sever operating conditions allowing it to fail more rapidly, hence lifetime information would be gained. Such operating conditions are called stresses. Stresses can be temperature, pressure, voltage, cycling rate, humidity, etc, that process is named Accelerated Life Testing
