GB/T 223.4-2008 《Alloyed steel - Determination of manganese content - Potentiometric or visual titration method》 Related products
This standard specifies methods for the determination of manganese content in steel and alloys, including the potential Titrimetric method and the visual Titrimetric method. It is suitable for the determination of manganese content in the mass fraction range of 2% to 25%. The standard specifically states that cerium and vanadium may interfere with the determination results; when the cerium content exceeds 0.01% or the vanadium content exceeds 0.005%, the theoretical value correction is required. The standard also refers to relevant specifications such as Precision, Sample sampling and Preparative methods to ensure the Reliability and conformity of the test.
