Aging Test Calculator

Design your accelerated aging study in seconds:

Enter target shelf life. Specify how many months or years of real-time aging you want to simulate.

Set your temperatures. Enter the ambient (real-world storage) temperature and the elevated (accelerated test) temperature in degrees Celsius. Common test temperatures are 55°C and 60°C for products stored at room temperature (25°C).

Choose a Q10 factor. The default Q10 of 2 means the reaction rate doubles for every 10°C increase. This is the most widely accepted value per ASTM F1980.

View results. The calculator shows the Accelerated Aging Factor (AAF) and the exact accelerated test duration required. For example, 1 year of real-time aging at 25°C might require only 42 days at 55°C with Q10 = 2.

Accelerated aging is grounded in chemical kinetics:

Arrhenius Equation: The aging acceleration factor is calculated as AAF = Q10^((T_test - T_ambient) / 10). Higher temperature differences produce larger acceleration factors.

Q10 Factor: Represents the rate increase per 10°C temperature rise. A Q10 of 2 (most common) means each 10°C increase doubles the degradation rate. Conservative studies may use Q10 = 1.8.

ASTM F1980: This standard provides the accepted methodology for accelerated aging of sterile barrier systems. It recommends Q10 = 2 and test temperatures not exceeding 60°C.

Limitations: Accelerated aging assumes the Arrhenius model holds — meaning the degradation mechanism doesn't change at elevated temperatures. Materials that melt, phase-change, or degrade differently at high temperatures may produce misleading results.

Ensure your accelerated aging study is valid:

• Don't exceed 60°C — Per ASTM F1980, test temperatures above 60°C risk activating different degradation mechanisms, invalidating the Arrhenius assumption.
• Always run real-time aging in parallel — Accelerated aging provides a claim with an asterisk. Real-time data is the gold standard for regulatory submissions.
• Use Q10 = 2 unless justified — A Q10 of 2 is the industry standard. Using a higher Q10 without supporting data will be questioned by regulators.
• Account for humidity — The standard Arrhenius model addresses temperature only. If your product is moisture-sensitive, consider environmental conditioning chambers.
