Metallic coatings - Hot dip galvanized coatings on ferrous materials - Gravimetric determination of the mass per unit area
The method is based on dissolving the coating on a surface of known area in inhibited acid and determination of the resultant loss in mass by weighing the sample before and after dissolving. Since knowledge of area of the surface is essential, it is mainly applicable to shapes whose areas are easy to determine.
