  Standard Classification of Coals by Rank. Note 1: Coals rich in inertinite or liptinite (exinite), or both, cannot be properly classified because, in those macerals, the properties that determine rank (calorific value, volatile matter, and agglomerating character) differ greatly from those of vitrinite in the same coal. Often, such coals can be recognized by megascopic examination.
