The variability of the time to failure is a function of the constancy of the parameters of the test, such as the test voltages, which should be monitored. It is also a significant material property. The Weibull slope factor, , is recommended as a measure of variability. is the slope obtained when percent failure is plotted against failure time on Weibull probability paper. Such a plot is called a Weibull probability plot (see Fig. 1).
The shape of the Weibull probability plot can provide addi
