Stability Test (Shelf Life):

Stability tests are generally performed to determine/verify the shelf life of the product. In stability tests, it is expected that there is no deterioration in the physicochemical structure of the product and that it is microbiologically acceptable.

Stability tests can be performed both by keeping the product during the normal shelf life and by changing the ambient conditions (such as raising the temperature to accelerate). Stability tests performed by raising the temperature are also called accelerated aging tests.

In the accelerated aging test, the test time is shortened by exposing the product to higher temperatures than the normal shelf life temperature and results are obtained in a shorter time

Aging tests in medical products are mostly performed as accelerated aging test. The method used for shelf life testing in medical products is the ASTM F 1980 standard.

According to this standard, the temperature that the product can tolerate according to the structure and packaging characteristics of the product and the real-time shelf life time are taken into account and the accelerated aging time of the product is calculated as a result of the calculation.
