Accelerated Aging Calculator: Shelf Life Aging Calculator

Accelerated Aging – oftentimes referred to as Accelerated Shelf-Life Testing – is commonly used in the medical device industry to accelerate the effects of time on a Sterile Barrier System to establish Shelf Life parameters. The Accelerated Aging process is based on the relationship of temperature and reaction rate where an increase in temperature increases the reaction rate.

Reference ASTM F1980-21

\begin{equation} \text{Accelerated Aging Time (AAT)} = \frac{\text{Desired Real Time (RT)}}{Q_{10} ^{\left(\frac{T_{AA} - T_{RT}}{10}\right)}} \end{equation}

Calculated Accelerated Aging Time (AAT):
Reset
NOTES
  1. The calculated AAT is typically rounded up to the nearest whole day.
  2. Westpak does not recommend aging packaging materials at temperatures exceeding +60ºC. Common TAAs are +50ºC, +55ºC, and +60ºC.
  3. Ambient temperature is typically between +20ºC to +25ºC. A temperature of +25ºC is a more conservative approach.
  4. The aging factor is typically between 1.8 – 2.5 with a value of 2.0 being the most common value.

This knowledge is critical across industries, from consumer goods to pharmaceuticals. The medical device industry, in particular, places a large emphasis on testing the shelf life of products. That’s because as time goes on, a product’s Sterile Barrier System can become altered as it faces stresses from time and the ambient environment. If a Sterile Barrier System becomes compromised, this can jeopardize the efficacy and safety of the medical device in question. Therefore, the FDA requires medical device manufacturers to determine a product’s shelf life before sending the product to market in the United States. However, sometimes it may take many months or even years before you can witness the toll aging takes on a product in real-time This is where accelerated aging, also known as accelerated shelf-life testing, comes into play. Accelerated aging is a type of testing that simulates the effects that time has on a product or package by subjecting it to elevated temperatures. This testing allows medical device manufacturers to determine a newly developed product’s shelf life and witness the long-term effects of aging without having to wait for years to see the real-time results.”

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. ”
