WEIBULL DISTRIBUTION METHOD FOR DETERMINING FAILURE RATE, MIL-PRF-39003 (Continued)
If no failures occur, the lot can be re-started at a higher stress
level only once. If no failures occur at the higher stress level,
the lot is not suitable for Weibull analysis.
After a minimum of 40 h, the failure count is again taken. If
no further failures occur, one is added to the count. Failure
rate is calculated by the following:

Z (t) = [- 0.2119 1n (1 - 0.0326) 105]/40 (17356)
Z (t) = [- 0.2119 (- 0.0331) 105]/6.9424 (105)
