Coal Rank Classifiion
The ASTM coal rank classifiion is based on a number of parameters obtained by various prescribed tests, which include calorific or heating value, volatile matter, moisture, ash, and fixed carbon (Figure ). Calorific or heating value of coal is defined as heat energy released as it undergoes complete combustion with oxygen.

Its usefulness is restricted, however, by its applicability to UK Carboniferous period coals only. Other, more widely applicable, coal rank classifiion systems are the ASTM (USA) and the United Nations/European Economic Community (UN/ECE) systems, both based on volatile matter (or 'fixed carbon') and calorific value.
