Use the Accelerated Life Test Design platform to create an accelerated life test design for one accelerating factor.
1. Select DOE > Special Purpose > Accelerated Life Test Design.
Notice that One accelerating factor is selected by default.
2. Under Factor Name, click X1 and type Temperature.
Notice that the Number of Levels is set to 3 by default.
3. Notice that the Factor Transformation is set to Arrhenius Celsius.
4. Enter 10 for both the Low Usage Condition and the High Usage Condition.

In this example, you construct a failure probability optimal ALT test design for a mechanical component. The single acceleration factor is torque, and the normal use stress is 35 Nm (newton meters). You want to estimate the time at which 10% of the units fail at the normal use stress. You construct a failure probability optimal ALT test.
Your test plan has the following characteristics:
• A total of 100 units are available for testing.
