The FITS data from Figure 1 is calculated at the 60% confidence level. According to National Semiconductor, the 60% level is a good estimate of the upper control limit for the FITS. At this percentage, you can claim that you are 60% confident that the actual failure rate is no higher than what is calculated using the Arrhenius equation .

Confidence Coefficient – probability that an interval estimator encloses the population parameter – that is, the relative frequency with which the interval estimator encloses the population parameter when the estimator is used repeatedly a very large number of times. The confidence level is the confidence coefficient expressed as a percentage.
