Abstract
Overview
ISO 609:2025 - "Coal and coke - Determination of carbon and hydrogen - High temperature combustion method" specifies a laboratory procedure for determining and in coal and coke by high‑temperature combustion and gravimetric absorption. The third edition (2025) updates the 1996 version and defines equipment, reagents, sample preparation, combustion conditions and calculations so results include carbonates and hydrogen in moisture and silicates (with provision for corrections).
