Scope
This standard specifies the principles, testing instruments, equipment, and materials for determining the reactivity and post-reaction strength of coke, as well as the sampling and preparation of samples, the testing procedures, the calculation of results, and the precision of the test. This standard applies to the determination of the reactivity and post-reaction strength of coke used in blast furnace ironmaking. Coke used for other purposes may be referenced for implementation.
