Define aging test time intervals (including time zero). Many years later, I still remember that lesson and always work with customers to ensure they pick the proper temperatures for their accelerated aging projects.”. endobj

The use of these equations allows the engineer to essentially make time go faster in order to prove out their packaging that much sooner. Q10 Approval by the Steering Committee under Step 2 and release for public consultation. Bottom line: Research your device’s materials so you don’t abuse the time machine. The accelerated aging time required to establish equivalence to real time aging is determined by dividing the desired shelf life by the accelerated aging factor (AAF). (Q10+ Δ 10°C reaction-rate constant, assuming a room temperature of 22°C.) At the heart of ASTM F1980 “Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices” are the Arrhenius equation and Accelerated Aging Factor (AAF) Determination (Sections 6 and 7).
Storage Temperature to be simulated (°C) Typical values are between 20°C and 25°C °C . We will continue to monitor the situation and update our event schedule accordingly. Define test conditions, room temperature (TRT), and accelerated aging …

Note: due to the coronavirus (COVID-19), several upcoming conferences have been postponed or cancelled. Understanding the Vicat Softening point for each of the plastic materials in a device is key to picking the proper temperature for aging. Have questions about an Accelerated Aging Project? Choosing an accelerated aging temperature significantly above the common temperatures of 50°C, 55°C and 60°C in order to obtain test results even quicker can have disastrous results. 2 0 obj

<> At the heart of ASTM F1980 “Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices” are the Arrhenius equation and Accelerated Aging Factor (AAF) Determination (Sections 6 and 7). Practical use of the AAF involves choosing an aging factor (Q10) which is typically a value of two (2) for packaging testing, an ambient temperature and an accelerated aging temperature.
To my surprise, some of the materials had melted and others had deformed horribly. By measuring this parameter at multiple times during the aging study, one can construct a relationship between this property and aging time.
Practical use of the AAF involves choosing an aging factor (Q10) which is typically a value of two (2) for packaging testing, an ambient temperature and an accelerated aging temperature. Once this is known, a safe and effective temperature can be utilized for the accelerated aging process.

One year, or 365 days divided by 8 = 45.6 days. Please contact us today, or call us at 1-800-229-4235. If Q10 = 2 and the accelerated aging condition is 55°C, or 30°C over an ambient temperature of 25°C, then the aging factor is 2^3 which equal 8. %PDF-1.5
One way to explain the use of the Arrhenius equation and Accelerated Aging Factor (AAF) Determination to someone outside of the profession is to describe it as a time machine. <>>> Therefore, 45.6 days at 55°C is equivalent to one year at an ambient temperature of 25°C. Because real-time testing is impractical, accelerated aging techniques must be used.

It’s true that accelerated aging is meant to do just that – accelerate the aging process.

Selection of the accelerated aging temperature involves a little more choice.
Let’s just say that’s when I learned my lesson with accelerated aging.
