This document gives guidelines for determining the average surface density over a measured area of anodic oxide or of a coating deposited autocatalytically, mechanically, by chemical conversion, by electrodeposition, by hot dip galvanizing and by chemical or physical vapour deposition using gravimetric and other chemical analysis procedures that have attained some degree of national or international standardization.
A variety of procedures are described and include:
-
gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate to determine the coating surface density;
-
gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to determine the coating surface density;
-
analytical procedures that utilize dissolution of the coating for determination of the coating surface density by instrumental chemical analysis methods.
With the exception of the gravimetric method as described in ISO 3892, this document does not give the measurement uncertainties of the methods cited.
