Abstract
Overview
ISO 8889:1988 is an international standard published by ISO that specifies a complexometric method for determining aluminium content in chromium ores and concentrates. The method applies to aluminium concentrations ranging from . This standard complements , which covers general instructions for chemical analysis of chromium ores and concentrates. The procedure includes detailed specifications for reagents, apparatus, sample preparation, and calculation of results to ensure reliable and reproducible measurement of aluminium in chromium minerals.
