ISO 18894:2018 Coke - Determination of coke reactivity index (CRI) and coke strength after reaction (CSR)
standard by International Organization for Standardization, 02/01/2018
More info
Full Description
ISO 18894:2018 specifies the equipment and techniques used for determining lump-coke (nominal top size 20 mm) reactivity in carbon dioxide gas at elevated temperatures and its strength after reaction in carbon dioxide gas by tumbling in a cylindrical chamber.
Main application is the testing of coke to be used in iron making blast furnaces (CRI~ 33, CSR~ 55). This standard can also be applied to other coke types (e.g. foundry coke), but limited precision is to be expected. Application to coke for non-iron making blast furnaces is beyond the scope of this document.
