1.1 This test method covers the determination of the particle size distribution of granular activated carbon. For the purposes of this test, granular activated carbon is defined as a minimum of 90 % of the sample weight being retained on a 180-μm Standard sieve. A U.S. mesh 80 sieve is equivalent to a 180–μm Standard sieve.
Note 1—For extruded carbons, as the length/diameter ratio of the particles increases, the validity of the test results might be affected.
1.2 The data obtained may also be used to calculate mean particle diameter (MPD), effective size, and uniformity coefficient.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3.1 Exception—All mass measurements are in SI units only.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
