    Image Description - 0703-1

    An uncaptioned figure shows the general relationship between reliability of a part in terms of failure rate and temperature. A curved line in the graph represents the relationship. The slope of the line increases non-linearly from left to right. Failure rate is plotted on the y-axis and temperature on the x-axis. The plot shows the failure rate for the same part at two different temperatures TA and TB, with TA < TB. No specific numerical values have been associated with any of the labels shown in the figure. The figure illustrates that by drawing a vertical line upward from TA and TB, which lie on the x-axis, until the lines intersect the curve and then continuing each line horizontally to the left until they intersect the y-axis, corresponding failure rates, lA (Lambda A) and lB, for TA and TB, respectively, are obtained.

    A legend on the left lists the parameters that are given in constructing the graph. The listed parameters include Specific part, Specific Derating Factor and Specific Chemical Activation energy.
