Highly accelerated life test

Highly accelerated life test is a way to test how long something will last by testing it in extreme conditions. For example, if you wanted to test how long a toy car would last, you could run a highly accelerated life test by putting it in a room with extreme heat, cold, humidity, or any other environmental condition that might break it down more quickly than usual. This way, you would be able to tell how long your toy car would last in its normal conditions by seeing how it does in the extreme conditions.
