$aISO 18787:2017 establishes basic principles and specifies requirements for the methods of determining water activity (aw) of food products for human consumption and animal feed within a measurement range of 0 to 1. The measurement principles are based on the dew-point measurement or on the determination of the change in electrical conductivity of an electrolyte or in the permittivity of a polymer.
