Abstract
Overview
establishes a standardized procedure for determining the total silicon content in leather using the reduced molybdosilicate spectrometric method. Published by SIST, this international standard is essential for the leather industry where understanding the silicon content of processed materials is critical for quality control, research, and product development.
