For coal, coke and biomass, customers can rely on Bureau Veritas analytical programs to assess the processability, performance and grade (of coal)

The industry standard for solid fuel evaluation is Proximate Analysis (ASTM D3172) indicating the percentage of weight of the fixed carbon, volatiles, ash and moisture content and Ultimate Analysis (ASTM D3176) which is specific to the reporting of compositional data for carbon, hydrogen, nitrogen, oxygen and sulfur.
