Method for measuring a permeation rate, a test and an apparatus for measuring and testing

A method is proposed for measuring water permeability of substrates. A reactive compound (Ca, Ba) which reacts with a diffusing material, e.g. water, is applied on the substrate and the change in time of transmissivity, reflectivity of the layer is monitored in time.
