Abstract
Overview
ISO 4140:1979 specifies a standardized potentiometric method for the precise determination of chromium content in and alloys. This international standard applies to all grades of these ferroalloys, providing a comprehensive procedure that includes sample preparation, reagents, apparatus, titration, and calculation of results. Developed by the ISO Technical Committee on Ferroalloys (ISO/TC 132), this method ensures consistent and reliable chromium analysis crucial in quality control and industrial applications.
