Abstract
Overview - ISO 5072:2021 for brown coals and lignites
ISO 5072:2021 specifies laboratory methods to determine the and the of brown coals and lignites. The standard describes sample preparation, required reagents and apparatus, step‑by‑step procedures and calculation formulas for both densities. It is applicable to general analysis test samples prepared to a nominal top size of 212 µm and references related moisture and sampling standards.
