Accelerated Aging Calculator (AAT)

Q: What is the formula used in the Accelerated Aging Calculator?

We use the Arrhenius-based AAF formula: AAF = Q10^((Ta - Ts)/10), where Q10 is usually 2.

Q: Is this AAT calculator free to use?

Yes, it's completely free and web-based, with no download or sign-up required.

Q: Can I download the results in Excel?

Currently, we don't support direct Excel download, but you can manually record the results.

Q: What are typical applications for AAT in medical devices?

Accelerated aging is used for medical device shelf-life validation, sterility assurance, and regulatory compliance.

Q: What is Westpak’s role in accelerated aging?

Westpak offers certified aging and performance testing aligned with ASTM and ISO standards.

Storage Temperature (°C): Accelerated Temperature (°C): Real-Time Aging Duration (days):

In industries where shelf-life, reliability, or material degradation matter—like medical devices, electronics, or packaging—understanding how time affects performance is crucial. Enter the Accelerated Aging Calculator (AAT Calculator), your go-to tool for estimating product lifespan using time-compression models like the Arrhenius Equation.

Whether you’re in quality assurance, R&D, or regulatory testing, this calculator simplifies accelerated aging time formulas to simulate long-term product performance under elevated temperature conditions.

What is an Accelerated Aging Calculator?

An Accelerated Aging Calculator is a scientific tool used to predict how quickly a material or product will age under elevated temperatures compared to real-time conditions. Based on the Arrhenius equation, it helps calculate the Accelerated Aging Time (AAT), a critical metric for testing product durability.

This method is especially important for:

Medical device validation
Packaging testing (e.g., Westpak standards)
Electronics shelf-life prediction

It bridges the gap between real-time aging and lab-simulated aging, enabling businesses to speed up product development and meet compliance timelines.

How to Use the Accelerated Aging Calculator

Here’s how to simulate years of aging in weeks:

Enter the storage temperature (°C) – your product’s normal environment.
Enter the accelerated temperature (°C) – the elevated lab condition.
Input the desired real-time duration (days/months/years).
Click “Calculate” to get the Accelerated Aging Time (AAT) using the standard Arrhenius equation.
