Standards Development
This International Standard specifies a routine method after fusion under inert gas for the determination of oxygen in steel and iron.
The method is applicable to mass fraction of oxygen between 0,001 % and 0,01 %.
Oxygen considerably influence the material properties of steel, particularly its hardness and corrosion tendency. Therefore determination of this element is a routine application in the steel industry. A typical steel sample can be analyzed directly in the impulse furnace without adding fluxes. This guarantees simple and reliable oxygen analysis with quick availability of repeatable results.This procedure is suitable for manufacturing control and inspection testing.
Combustion method offer significantly better quantitative data, rapid control methods than do other methods this method provides:High stability, Low background and Freedom from interferencesand take short time .
Superior stability reducing the time necessary for instrument drift corrections; making more of the operators time available to analyze production and other samples. The opportunity to increase productivity with a fully stable system providing fast, accurate results. This results in low analysis costs over a very long lifetime.
Because of this additional work by the instrument, substantial savings in manpower and time have been realized by the laboratory. In the analysis of a set of preliminary tests from the stainless steel furnace, approximately more than 80 min in laboratory time are saved due to combustion in one time.
