This standard specifies the method for the determination of aluminum content in sponge titanium, titanium and titanium alloys, and the applicable range is 0.010% to 8.50%. Method 1 is the alkali separation-EDTA complexation Titrimetric method, the determination range is 0.80% to 8.50%, which is the arbitration analysis method; Method 2 is the Inductance coupled plasma atomic emission spectroscopy (AES) method, the determination range is 0.010% to 8.50%. Sample Handling, titration operation and interference elimination are described in detail in the standard to ensure the accurate determination of aluminum content.
