GB/T 223.11-2008 《Iron, steel and alloy - Determination of chromium content - Visual titration or potentiometric titration method》 Related products

GB/T 223.11-2008 for the determination of chromium content in steel and alloys, providing visual titration and Potentiometric titration, poten-tiometry two methods. Suitable for all kinds of steel and alloy products. Visual titration determines the endpoint by the change of indicator Color, Potentiometric titration, poten-tiometry is determined by the change of potential. The standard specifies the required instruments, such as Burette, Potentiometric titrator, etc., and specifies the preparation of reagents. Detailed description of Sample Handling, covering steps such as dissolve and oxidation. Standardize two titration operation procedures, such as Color observation of visual titration, Potentiometric titration, and potentiometric tiometry potential monitoring. According to this standard, chromium content can be accurately determined, providing key data support for steel and alloy mass evaluation and production process optimization.
