Arrhenius plot

This is a method of applying a calculation formula based on the temperature dependence of the chemical reaction rate to the accelerated aging test.
Plotting the test results of several end-of-life test results on a graph with time on the horizontal axis and the logarithm of the reciprocal of absolute temperature on the vertical axis will line up in a straight line. Higher temperature = Shorter service life The service life in the actual temperature environment is calculated by approximation from a straight line obtained from multiple data.
