ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis. It provides a rough estimate of the heating value of coal.
Different analyses and tests use different preparations of coals, usually recorded in the results as some type of "basis." The following standard coal analysis bases can be converted to each other for standard reporting (ASTM method D3180-12; American Society for Testing and Materials, 2013, p. 515–517).

1. As tested/Air-Dried Basis (ADB/ad) Air-dried basis adalah basis dimana % weight fixed carbon, moisture, volatile matter dan ash dihitung tanpa surface moisture. Sample dianalisis setelah mendapatkan perlakuan air drying sehingga surface moisture tidak ikut terhitung di dalam sample batu bara. 2. As Received Basis (ARB/ar)
What is ARB and ADB in coal? ARB puts all variables into consideration and uses the total weight as the basis of measurement. ADB (air-dried) basis neglect the presence of moistures other than inherent moisture unlike ARB which uses total moisture. This results in different measured GCV on different Basis.
