This tool calculates the accelerated aging of materials based on your environmental input variables.
Accelerated Aging Calculator
This calculator helps estimate how long a product can last under accelerated aging conditions by calculating the equivalent real-time aging.
How to Use
- Enter the Temperature (in °C) at which the accelerated aging test is conducted.
- Enter the Activation Energy (in eV) of the product. This value can be obtained from detailed product data sheets or lab tests.
- Enter the Elapsed Time (in hours) the product is subjected to the accelerated aging conditions.
- Enter the Reference Temperature (in °C) which is typically the normal use temperature of the product.
- Enter the Reference Time (in hours) which is the known or estimated lifetime of the product at the reference temperature.
- Click on “Calculate” to see the accelerated aging result in terms of equivalent real-time aging hours.
How it Calculates the Results
The calculator uses the Arrhenius equation to calculate the acceleration factor, which determines how much faster the aging process occurs at the accelerated test temperature compared to the reference temperature. The formula is:
Acceleration Factor = exp((Ea / k) * (1 / Tr - 1 / T))
Where:
- exp – Exponential function
- Ea – Activation energy in eV
- k – Boltzmann’s constant (8.617333262145e-5 eV/K)
- Tr – Reference temperature in Kelvin (K)
- T – Accelerated aging temperature in Kelvin (K)
Limitations
Note that this calculator provides an estimate and results can vary based on the accuracy of the entered values, especially the Activation Energy. For precise aging analysis, detailed lab tests and empirical data are recommended.
