How does one use the results of Accelerated stability testing for chemicals to determine the typical Shelf life and Expiry Date?
e.g. Suppose the typical storage is going to be at 25 C and the expected shelf life is 2 years (as printed on the labels or the best-before date).
Now in the interest of time suppose we test at a higher temperature how do we extrapolate those numbers to the typical shelf life at room temperature.
Any standard protocols for this? Also what's a reasonable high temperature to use for the accelerated tests. I am dealing with a fairly temperature stable & nonreactive material here. 60 C?
Stability testing seems quite common in the Pharma industry etc. so I'm sure there's norms out there.
Note that I'm not dealing with a drug / medicine / food etc. This is strictly for an intermediate which will not be consumed directly by the end user.
