1 Scope
This document specifies a method for obtaining a relative measure of the plastic behaviour
of hard coal when heated under prescribed conditions. The method is used to obtain
values of the plastic properties of coals and blends used in carbonization and in
other situations where determination of plastic behaviour of coals is of practical
importance.
NOTE The empirical nature of this test requires proper equipment calibration to produce fluidity readings which are a true indication of the relative plastic behaviour of the coal.
