ASTM's carbon standards are instrumental in evaluating and testing activated carbon used primarily in industrial applications. The activated carbons can be in the solid, granular, palletized, or impregnated forms. These carbon standards are helpful in the determination of the various physical and chemical properties of activated carbon including reaction pH, particle size, absorption, and contents and activities of certain chemical substances. The said properties can be assessed by aqueous phase isotherm technique, air jet sieving, micro-isotherm technique, ashing, and rapid small-scale column tests. These standards allow laboratories and other chemical facilities to examine and assess activated carbons to ensure their safe use and application.
