Abstract
Overview
ISO 548:1981 (second edition) defines a barium sulphate gravimetric method for the determination of barium oxide (BaO) content in manganese ores. This International Standard replaces the 1975 edition and is intended to be read in conjunction with (general chemical analysis instructions). The method provides laboratory procedures from sample preparation to expression of results, supporting reliable gravimetric analysis for quality control and materials characterization.
