Carbon Materials –
Determination Method of the Bulk Density
1 Scope
This Standard specifies the principle, apparatus, specimen, test procedures and result
calculation for the determination of bulk density of carbon materials.
This Standard is applicable to determination of bulk density of carbon materials at
room temperature.
2 Normative References
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments
(excluding corrigendum) or revisions do not apply to this Standard, however, parties
who reach an agreement based on this Standard are encouraged to study if the latest
versions of these documents are applicable. For undated references, the latest edition
of the referenced document applies.
