Use the Reliability Demonstration calculator to test a specified number of units for a specified period of time. If fewer than k units fail, the demonstration passes, and you can conclude that the product reliability meets or exceeds a reliability standard. We pose the reliability demonstration as a hypothesis test:

where p is the probability of survival time at t* for the new product and p* is the standard probability of survival at time t*.
