ISO 11256:2015 PDF

Scope: This International Standard specifies a method to provide a relative measure for evaluating the formation of clusters of iron ore pellets when reduced under conditions resembling those prevailing in shaft direct-reduction processes. This International Standard is applicable to hot-bonded pellets.
