Refer to given Exercise. Find the appropriate plan using Handbook H-108 if failed items are not replaced during the test.
Exercise
A time-terminated life testing plan is desired that will accept lots with a mean life of 6000 hours with a probability of 0.99 and will accept lots with a mean life of 2000 hours with a probability of 0.10.
The test should be terminated by 1200 hours. Items that fail will be replaced immediately. Determine the plan using Handbook H-108, assuming that the time to failure is exponential.
