1.1 This test method covers the determination of the mechanically tapped density of powdered and fine mesh activated carbon. For the purpose of this test method, “powdered carbon” is defined as having a mean particle diameter less than 45 µm, and “fine mesh carbon” is defined as having a particle size predominately between 80 and 325 U.S. Standard mesh.

1.2 The values in SI units are to be regarded as standard. No other units of measure are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to determine the density expressed in g/mL for powdered or fine mesh carbon. Due to the nature of the small particles, the density of these carbon types cannot be measured using the same procedure as granular carbon.
