Good Afternoon,<br />
<br />
We are going through legacy test procedures to determine failure probabilities for evaluating the efectiveness of tests, whether more samples and/or cylces/specimens should be performed to assure a low enough failure probability at a high level of confidence.<br />
<br />
One of these legacy tests is performed on one sample of a mechanism 30 times. &nbsp;If the mechanism does not operate one time in those 30 cycles, the entire population of the mechanism fails.<br />
<br />
What failure probability and confidence level is associated with this test, and what should it be, if not it's current probability and level?<br />
<br />
I appreciate any guidance you can provide.<br />
<br />
Thank you<br />
