Inorganic Surface Coatings – Measurement of Coating Thickness – Beta Backscatter Method. ISO 3543:2000 describes the beta backscatter method, a technique for measuring the thickness of inorganic surface coatings. This method is particularly useful for coatings on metallic substrates and works by bombarding the surface with beta particles. A detector measures the backscattered radiation, with the amount of backscatter proportional to the coating’s thickness. The standard provides detailed instructions on calibrating equipment and preparing samples to ensure accurate and reliable results. The method is non-destructive and widely used in quality control to verify that coatings meet thickness and performance specifications.
