About Accelerated Aging
Arrhenius Equation
The Arrhenius equation describes the relationship between reaction rate and temperature, allowing prediction of product shelf life under different conditions.
Acceleration Factor
Higher temperatures accelerate chemical degradation. Each 10°C increase typically doubles reaction rates (Q10=2), but this varies by material.
Testing Standards
Common standards include ISO 188, ASTM F1980, and ICH Q1A for pharmaceutical stability testing using accelerated aging protocols.
Accelerated Aging Calculator: Predict Product Shelf Life with Scientific Precision
In product development and quality assurance, understanding how materials degrade over time is crucial. The Accelerated Aging Calculator is a powerful tool that uses the Arrhenius equation to estimate real-world aging effects in a fraction of the time. This scientific approach helps manufacturers, researchers, and quality control professionals predict product stability and shelf life without waiting for years of natural aging.
What Is Accelerated Aging Testing?
Accelerated aging testing simulates long-term environmental effects in a compressed timeframe by exposing products to elevated temperatures. This method is widely used in:
- Medical devices (ISO 10993, ASTM F1980)
- Pharmaceuticals (ICH Q1A stability testing)
- Electronics (predicting component lifespan)
- Polymers & plastics (durability testing)
How It Works: The Arrhenius Equation
The calculator uses the Arrhenius equation:
How to Use the Accelerated Aging Calculator
Step 1: Enter Test Parameters
- Real-world temperature (°C): Typical storage conditions (e.g., 25°C for room temperature).
- Accelerated temperature (°C): Elevated test temperature (e.g., 60°C).
- Test duration (days): How long the product is exposed to accelerated conditions.
Step 2: Define Activation Energy
- Activation energy (kJ/mol): A material-specific value (default = 80 kJ/mol).
- *Low (50 kJ/mol):* Less sensitive to temperature (e.g., some metals).
- *Medium (80 kJ/mol):* Common for polymers and pharmaceuticals.
- *High (110 kJ/mol):* Highly temperature-sensitive materials.
Step 3: Optional Q10 Factor
- The Q10 factor estimates degradation rate changes per 10°C increase. If unknown, the tool calculates it automatically.
Step 4: Calculate & Interpret Results
The tool provides:
✅ Acceleration factor (e.g., “12x faster”)
✅ Equivalent real-world aging time (in days, months, or years)
✅ Detailed breakdown of different temperature effects
Why Use This Calculator?
✔ Save Time & Costs – Predict years of aging in weeks.
✔ Improve Product Reliability – Identify weak points before market release.

Limitations & Considerations
⚠ Single-Step Reactions Only – The Arrhenius model assumes uniform degradation. Complex multi-stage reactions may require additional testing.
⚠ Material-Specific Ea – Incorrect activation energy leads to inaccurate predictions.
⚠ Non-Thermal Factors – Humidity, UV, and mechanical stress aren’t accounted for.
