ISO/TR 17055 specifies a method for the determination of the content of silicon in steel by means of inductively coupled plasma emission spectrometry. The method is applicable to silicon contents of mass fraction 0,02 % to 5 %.
The method uses a calibration based on a very close matrix matching of the calibration solutions to the sample and close bracketing of the contents around the approximate…
This International Standard specifies a method for the determination of the impurities content in oilseeds used as primary industrial materials. It also defines the various categories of what are usually understood to be impurities.
