Scope

This Standard specifies the principles of coke determination of reactivity and strength after
reaction, test instruments, apparatuses and materials, sampling and sample preparation,
test procedures, calculation of results and degree of precision.
This Standard applies to the determination of reactivity of coke for blast furnace iron
making and strength after reaction; coke for other purposes may refer to this Standard for
implementation.
