GB/T 4702.5-2008 《Chromium metal - Determination of aluminium content - EDTA titrimetric method and flame atomic absorption spectrometric method》 Related products

This standard specifies the method for the determination of aluminum content in chromium metal by Titrimetric method and flame atomic absorption spectroscopy (AAS). It is suitable for the determination of chromium metal samples with aluminum content ranging from 0.10% to 1.00%. The standard details the specific operation steps of sample dissolving, titration and Light spectrum analysis, which provides a scientific basis for the quantitative analysis of aluminum content in chromium metal materials.
