-====The Reliable Life====
+#REDIRECT [[Distributions_Used_in_Accelerated_Testing]]
-For the 2-parameter Weibull distribution, the reliable life,  <math>{{T}_{R}}</math> , of a unit for a specified reliability, starting the mission at age zero, is given by:
-::<math>{{T}_{R}}=\eta \cdot {{\left\{ -\ln \left[ R\left( {{T}_{R}} \right) \right] \right\}}^{\tfrac{1}{\beta }}}</math>
-This is the life for which the unit will function successfully with a reliability of  <math>R({{T}_{R}})</math> . If  <math>R({{T}_{R}})=0.50</math>  then  <math>{{T}_{R}}=\breve{T}</math>,
-the median life, or the life by which half of the units will survive.
