DESCRIPTION
BS ISO 18894:2018
This standard BS ISO 18894:2018 Coke. Determination of coke reactivity index (CRI) and coke strength after reaction (CSR) is classified in these ICS categories:
- 75.160.10 Solid fuels
This document 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.
