MT 46.3 - Accelerated storage procedure

Content Handbook J


Outline of method

A sample is placed in a glass bottle (or another suitable container), which is subsequently closed and placed in an oven at a specified temperature for a defined period of time.



The objective is to simulate the normal long-term ageing of a formulation by heating. Although actual data from a product in sales packs and stored in e.g. warehouses is preferable, the accelerated storage test provides useful guidance on performance after storage since many formulations that perform poorly in the accelerated test do not have satisfactory shelf lives (of at least 2 years) in hot or temperate climates.

The mehod is usable for solid and liquid formulations.
