(Test Method)Standard Test Method for Apparent Density of Activated Carbon
Standard Test Method for Apparent Density of Activated Carbon
SIGNIFICANCE AND USE
This test method provides a method for determining the packed density of a bed of granular activated carbon. Determination of the packed density is essential when designing vessels to hold the material and for ordering purposes when procuring materials to fill existing vessels.
SCOPE
1.1 This test method covers the determination of the apparent density of granular activated carbon. For purposes of this test method, granular activated carbon is defined as a minimum of 90 % being larger than 80 mesh.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement 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 and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1Apparent density (bulk density) is determined on a granular sample by measuring the volume packed by a free fall from a
vibrating feeder into an appropriately sized graduated cylinder and determining the mass of the known volume. Other packing
procedures can result in different apparent densities.
3.1 Apparent density (bulk density) is determined on a granular sample by measuring the volume packed by a free fall from
a vibrating feeder into an appropriately sized graduated cylinder and determining the mass of the known volume. Other methods
for determining apparent density of granular or powdered materials exist. These may involve vibration or tapping of the receiving
vessel either while it is being filled or afterwards. Application of these methods to granular activated carbon may give packed
density values that differ from those determined by this test method.
4. Significance and Use
4.1 This test method provides a method for determining the packed density of a bed of granular activated carbon. Determination
of the packed density is essential when designing vessels to hold the material and for ordering purposes when procuring materials
to fill existing vessels.
