GB/T 15247-2008 Microbeam analysis—Electron probe microanalysis—Guidelines for determining the carbon content of steels using calibration curve method
Abstract
This standard specifies the correction curve method for determining the carbon content in carbon steel and low-alloy steel (other alloy elements with a mass fraction of less than 2%) using an electron probe. This standard includes sample preparation, X-ray detection, establishment of correction curves, and evaluation of the uncertainty of carbon content detection. This standard is applicable to the determination of carbon content in steel with a carbon mass fraction of less than 1%. When the carbon content is higher than 1%, the detection accuracy will be greatly affected, and it is not suitable for this standard. This standard is applicable to vertical incidence and spectrometers, but not to energy spectrometers.
