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.

 

Scope

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.

 

MT 46.4 - Accelerated storage procedure

 

Content Handbook P

 

Reason for Revision

The method was revised to harmonize the accelerated storage procedure for all formulation types. Storage conditions (Note 2) remain unchanged.

CIPAC MT 46.4 supersedes all previous versions of MT 46 for accelerated storage.

Outline of method

A sample is transferred to a suitable container which is subsequently closed and placed in an oven at a specified temperature for a defined period of time. After removal from storage, the container with the sample is left to equilibrate to ambient conditions before performing any tests.

 

Scope

The objective of this method is to simulate the normal long-term ageing of a formulation under conditions accelerated by heating. It is applicable to all formulation types.

The method describes conditions for storage and does not give results. Tests performed after accelerated storage are not part of this method.
