	The Arrhenius life-stress model (or relationship) is probably the most common life-stress relationship utilized in accelerated life testing. It has been widely used when the stimulus or acceleration variable (or stress) is thermal (i.e., temperature). It is derived from the Arrhenius reaction rate equation proposed by the Swedish physical chemist Svandte Arrhenius in 1887.

	~~Content 1~~		In basic life data analysis, units are tested under normal use conditions in order to obtain information about a product’s failure behavior. In some cases, however, it is desirable to obtain this information more quickly than is possible with use level testing. For example, products with long lifetimes or short periods between design and release, as well as products that are operated continuously, may produce results too slowly with basic life data analysis.
