This document specifies a method of determining the total carbon and the total hydrogen in coal and coke, by the Liebig method.
Abstract
Overview
ISO 625:2025 - "Coal and coke - Determination of carbon and hydrogen - Liebig method" specifies a laboratory procedure for measuring total carbon and in coal and coke by combustion (Liebig method). The method combusts a known mass of sample in oxygen, oxidizes incomplete combustion products over copper oxide, and collects the resulting water and carbon dioxide for . The standard replaces and updates apparatus, reagents and procedural details.
