The document specifies the formula for the calculation. In this ratio, only sodium oxide and potassium oxide combined in the form of silicates is considered. Replaces ISO Recommendation R 1689-1970.
Abstract
Overview
ISO 1689:1976 is an international standard that provides the in sodium and potassium silicates used for industrial applications. This standard ensures consistent and accurate evaluation of these silicate materials by focusing specifically on the oxides combined in the silicate form. It replaces the earlier ISO Recommendation R 1689-1970 and is part of a series of ISO standards that govern the analysis and characterization of sodium and potassium silicates.
