1.1 This test method covers the determination of the dusting attrition of granular activated carbons. For the purpose of this test method, the dust attrition coefficient, DA , is defined as the weight (or calculated volume) of dust per unit time, collected on a preweighed glass-fiber filter, in a given vibrating device during a designated time per unit weight of carbon. The initial dust content of the sample may also be determined. Granular activated carbon is defined as a minimum of 90% being larger than 80 mesh (0.18 mm) (see Test Methods D 2867).

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.
