This standard specifies the steps and requirements for the determination of aluminum content in ferrosilicon by three methods, including the chrome azure S Spectrophotometric method, spectrophotometry, EDTA Titrimetric method and flame atomic absorption spectroscopy (AAS) method. The standard is applicable to the determination of aluminum content in different ranges, covering aluminum content from 0.05% to 5.00%. The scope of application of each method, reagent requirements and measurement principles are described in detail to ensure the accuracy and repeability of the analysis. The standard provides important technical support for the quality control and composition analysis of ferrosilicon products.
