Abstract
Overview
ISO 502:2025 - Hard coal - Determination of caking power - Gray‑King coke test - specifies the standardized laboratory method for assessing the caking power of hard coal using the . The method carbonizes a representative coal sample under controlled heating and compares the resulting coke residue with standard reference residues. For highly swelling coals, the procedure uses an additive (standard electrode carbon) to determine the minimum admixture required to produce a standard coke type.
