Scope
This part of GB/T 8704 specifies the determination of aluminum content in vanadium iron using the chromotropic S spectrophotometry and EDTA titration methods. This part is applicable to the determination of aluminum content in vanadium iron. The determination range (mass fraction) of the chromotropic S spectrophotometry is 0.10% to 0.80%; the determination range (mass fraction) of the EDTA titration method is 0.50% to 3.50%.
