	~~====Determining~~ Test ~~Time for Available Units====~~		#REDIRECT [[Reliability Test Design]]
	The way that one determines the test time for the available number of test units is quite similar to the process described previously. In this case, one knows beforehand the number of units, <math>n</math> , the number of allowable failures, <math>f</math> , and the confidence level, <math>CL</math> . With this information, the next step involves solving Eqn. (relcum) for <math>{{R}_{TEST}}</math> . With this value known, one can use the appropriate reliability equation to back out the value of <math>{{t}_{TEST}}</math> , since <math>{{R}_{TEST}}=g({{t}_{TEST}};\theta ,\phi )</math> , and <math>{{R}_{TEST}}</math> , <math>\theta </math> and <math>\phi </math> have already been calculated or specified.
