This Standard specifies the method that uses X-ray spectrometric method to test the surface coating weight (thickness) of electrical steel. This Method is for measuring the coating weight per unit area of a sample at room temperature. The measurement results can also be expressed by the thickness of the coating. This Standard is applicable to the electrical steel that contains stable, undisturbed, X-ray fluorescence intensity characteristic elements in surface coating. The measurement range of a given coating material depends primarily on the available characteristic X-ray fluorescence intensity and acceptable measurement uncertainty. And it varies depending on the instrument and measurement method used.
