BS ISO 16592:2012

This standard BS ISO 16592:2012 Microbeam analysis. Electron probe microanalysis. Guidelines for determining the carbon content of steels using a calibration curve method is classified in these ICS categories:

• 71.040.50 Physicochemical methods of analysis

This International Standard gives guidance on a method for the determination of the carbon content in steels containing other alloying elements (less than 1 % to 2 % by mass) using the calibration curve method. It specifies the sample preparation, X-ray detection, establishment of the calibration curve and the procedure for the determination of the uncertainty of the measured carbon content. It is applicable to steels containing a mass fraction of carbon of less than 1,0 %. The method is not applicable to steels with higher carbon contents, which could significantly affect the accuracy of the analysis results.

This International Standard applies to analyses performed using normal beam incidence and wavelength-dispersive X-ray spectrometry; it is not designed to be used for energy-dispersive X-ray spectrometry.
