The typical number of measuring points required by ICH Q1A (R2) on small to medium sized stability chambers is 9 (4 corners top and bottom shelf+ center) – fixed directly on the shelves in empty/loaded chamber. For larger chambers it is recommended to place 5 measuring points on minimum 3 layers or even on each layer with sample readings every 1- 5 minutes during 24/48 or 72 hours.

As example the acceptance criteria for a standard stability chamber with setpoint of +37°C is that all measurements throughout the chamber do not individually differ by more than 2°C for temperature and 5°C for relative Humidity.

Typical validations include:

Up to 15 temperature points logged over 24 hours.
Up to 12 humidity points logged over 24 hours
