Accelerated Aging Time (AAT)

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 F1980-16

\begin{equation} \text { Accelerated Aging Time }​ (A A T)=\frac{\text { Desired Real Time }(R T)}{Q_{10} ​ \scriptsize\left[\left(T_{A A}-T_{R T}\right) / 10\right]} \end{equation}

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 AATs 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.
