Scope

ISO 21807:2004 gives basic principles and requirements for physical methods of determining the water activity of products intended for human consumption and the feeding of animals.
Water activity can be used to predict microbial growth and determine the microbiological stability of a food product, and it also provides an important, quantitatively determinable criterion for estimating the times for which a foodstuff can be kept.
