This document specifies an alternative method of determining the total sulfur mass fraction of coal and coke by high-temperature combustion by Coulomb titration.
Abstract
Overview
ISO 20336:2025 specifies an alternative analytical method for determining the total sulfur mass fraction in . The method uses (1 150 ± 10 °C) followed by of the evolved sulfur oxides in an electrolytic cell. It is intended for laboratories and instrument users who require an automated, calibrated procedure to report total sulfur on an air‑dried or other specified basis.
