27、c behaviour of 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

28、test requires proper equipment calibration to produce fluidity readings which are a true indication of the relative plastic behaviour of the coal.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this
