Abstract
Overview
ISO/DTS 4189 presents a standardized inductively coupled plasma optical emission spectrometric (ICP-OES) method for the precise determination of sodium content in magnesium and its alloys. This international standard is essential for quality control and material certification, particularly due to sodium’s significant impact on the mechanical properties of magnesium alloys. The standard outlines procedures for sample preparation, analysis, calibration, and data interpretation to ensure accurate measurement of sodium concentrations ranging from 0.0002% to 0.05% by mass.
