Using the Accelerated Aging Time (AAT) calculator is simple. To use the calculator, you will need to enter the following four variables: Desired Real-Time in days, the Accelerated Aging Temperature (TAA) and Ambient Temperature (TRT) in degrees Celsius, and the Aging Factor (Q10). Below, we’ve outlined a step-by-step process for using our Accelerated Aging calculator: Enter the desired real-time in months. Input the TAA and TRT values, both in Celsius, for your product. Input the Aging Factor Q10 value for your product. (The default Q10 value is set at 2). Click “Calculate” at the bottom of the calculator to determine AAT, rounded up to the nearest day. If you’ve not already done so, complete the short form to see the result.
