Previous papers have been published with theoretical attempts to improve the so called "Rapid Chloride Permeability Test" and how to convert it to a reliable method for calculating chloride diffusion coefficients. The approach was based on considering the fundamentals of electrochemistry for ionic transport in electrolytes by the use of Nernst-Plank and Nernst-Einstein equations. In the present paper experimental details are given in order to compare natural diffusion and migration tests. The results indicate reasonable agreement between both test types and the soundness of the simplified assumptions.
