Overview
ISO 2355:1972 specifies a standardized gravimetric method for the chemical analysis of magnesium and its alloys, focusing on the determination of rare earth element (REE) content. This internationally recognized standard applies to the measurement of rare earths ranging from 0.2% to 10% by mass, specifically in samples devoid of thorium. It covers the entire analytical procedure including sample preparation, reagent use, apparatus requirements, testing method, result expression, and reporting.
This method is vital for industries where precise quantification of rare earths in magnesium alloys is required for quality control, material certification, and research and development purposes.
