    I am conducting water barrier testing of a nanocomposite as per ASTM D570. Basically immersing the samples in water and testing the weight regularly in order to draw the graph of percentage of relative mass uptake vs. square root of time and ultimately calculate diffusion coefficient. Now, the ASTM standard asks us to maintain the thickness constant at 3.2 +/- 0.3 mm. Why so ? If Diffusion coefficient is a constant why thickness becomes so critical.

    Wooly Tomcat It does, but not anywhere close to the temperature differences discussed here, if you were doping a silicon wafer with germanium for example, the differences in diffusion due to temperature is very small on a per degC basis. However if you started diffusing at 0.1*Tmelt, and then compared it to 0.5*Tmelt, you would notice a considerable improvement.
