The Accelerated Aging test can be run to simulate a designated time period ranging from 1 month to 5 years (or longer). The time of simulated aging depends on the temperature at which the products are held. For example, at 55°C using an ambient temperature of 25°C, 6.5 weeks is equivalent to 1 year on the shelf. So at these parameters, 13.0 weeks would be equivalent to 2 years on the shelf and 32.5 weeks would be equivalent to 5 years on the shelf.
After the samples have been aged, they are removed from the chamber and brought back to room temperature. Following the aging, the samples can be returned to you for further examination (such as functionality tests), or we will retain the samples to perform additional testing to confirm stability (i.e., package integrity/microbial aerosol barrier challenge, seal peel, or other physical tests).
Recommended replicates: You may age as many samples as you need. The number of samples should be based on the number of time periods to be examined, and the testing to be performed after aging.
Please use the Accelerated Aging Parameters form along with the Sample Submission Form when submitting samples.
