Standard Test Method for Determination of Particle Size of Fine Mesh and Powdered Activated Carbon by Air-Jet Sieving

Importancia y uso:

5.1 The particle size of fine mesh and powdered activated carbon is sometimes used to evaluate filter cake filtration rates and the filter penetration in filtering applications.

5.2 The selection and handling of fine mesh or powdered activated carbon, and operation of processes using fine mesh or powdered activated carbon, requires the knowledge of the particle size.

5.3 This test method is intended for single sieve testing only. For determination of particle size distribution of a sample, the test must be repeated using sieves with different openings.

Note 1: Relative humidity (RH) can affect the repeatability and accuracy of this test. Activated carbon not at equilibrium with the RH of the ambient air may lose or gain weight accordingly, dependent upon whether the carbon picks up or loses moisture.
