Three forces can mechanically degrade a granular activated carbon: impact, crushing, and attrition. Of these three, attrition, or abrasion, is the most common cause of dust formation in actual service. Published test procedures to determine the "hardness" of activated...
1.1 This test method covers determination of the pH of a water extract of activated carbon. 1.2 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and...
This guide presents a procedure for evaluating the resistance to dusting attrition of granular activated carbons. For the purpose of this guide, the dust attrition coefficient, DA, is defined as the weight (or calculated volume) of dust per unit time, collected on a preweighed filter,...
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...
1.1 This test method covers the determination of the water soluble content of new (virgin, unused) granular and powdered activated carbons. Water solubles are materials that can be extracted by distilled water under reflux conditions and are expressed as a percentage of dry...
This guide covers the evaluation of activated carbons for gas-phase adsorption. It presents a procedure for determining the dynamic adsorption capacity, No, and critical bed depth, dc, for an activated carbon used to remove a specific adsorbate from a gas stream under...
This test method covers determination of the pH of a water extract of activated carbon. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. This standard does not purport to address all of the safety concerns, if...
This standard specifies two empirical methods for the quantitative determination of the loss of mass from a plastic material under defined conditions of time and temperature, in the presence of activated carbon. These methods are used, in particular, for the quantitative determination...
5.1 Activated carbons used in gas-phase adsorption may be subjected to heating, either from heat applied externally to the carbon bed, or heat generated by radioactive4 contaminants, or by the adsorption process itself. If the application of heat is sudden, or if no ample means...
1.1 This test method covers the determination of reference ignition temperature of granular activated carbon in flowing air. This test method provides a basis for comparing the ignition characteristics of different carbons, or the change in ignition characteristics of the same...

This test method covers the determination of the water soluble content of (unused) granular and powdered activated carbons. Water solubles are materials that can be extracted by distilled water under reflux conditions and are expressed as a percentage of dry carbon weight. The...
This test method describes a procedure for the determination of total ash content of activated carbon. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. This standard does not purport to address all of the safety...
