The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and polishing and etching coal. These standards also include the thermophysical property tables for methane, ethane, propane, normal butane, and isobutane.
Coal with less than 69% fixed carbon is classified by its heating value. Volatiles and carbon are on a dry mineral free base; heating value is based on the moisture content as mined, but without any free water. The ISO has a coal ranking system that also ranks coals; the .

4.1 This classification establishes categories of coal based on gradational properties that depend principally on the degree of metamorphism to which the coal was subjected while buried. These categories indicate ranges of physical and chemical characteristics that are useful in making broad estimates of the behavior of coal in mining, preparation, and use.

classification of coal and represents a real health and safety concern as coals high in volatiles have an increased risk of spontaneous combustion. FIXED CARBON (STANDARD METHOD: ASTM D5142, ISO 17246) • The fixed carbon content of coal is determined by subtracting the percentages of moisture, volatile matter and ash from the original mass
Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semi-anthracite, semi-bituminous and sub-bituminous. the anthracite is the oldest coal from a geological perspective.
