The purpose of stability testing is to provide evidence that under influence of a variety of environmental factors the quality of a product varies with time.It helps to establish a re-test period or a shelf life for the product and recommended storage conditions.
1) Long term stability testing for 12 months
2) Intermediate 6 months
3) Accelerated for 6 months
Stability testing is conducted at room temperatures to reproduce actual storage conditions.
Accelerated stability testing is carried out at higher temperatures to simulate long term.
