In the X‐ray fluorescence analysis of steels, a correction method is usually used to eliminate absorption‐enhancement effects. It is a desirable that the correction factors should be common to all experimental conditions and therefore the fluorescent X‐ray intensity should be specified in a common unit. For this purpose, the JIS method converts the fluorescent X‐ray intensity into a tentative analytical value from the calibration curve of binary alloys, while the α‐correction methods employs the ratio of the intensity of an analytical sample to that of a pure substance for the fluorescent X‐ray intensity. In this report a detailed comparison of these methods is made, and the good and bad points of the JIS method discussed.
