Standard Test Method for Bulk Density by Physical Measurements of Manufactured Carbon and Graphite Articles

SIGNIFICANCE AND USE
Bulk density as determined by this test method is a basic material property of importance in manufacturing and application of carbon and graphite.  
This test method can be used for quality and process control, material characterization and description, and other purposes.
SCOPE
1.1 This test method covers the determination of the bulk density of manufactured articles of carbon and graphite of at least 500 mm  volume. The bulk density is calculated to an accuracy of 0.25%, using measurements of mass and dimensions in air at 25 + 5°C.  
1.2 This standard does not purport to address 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.
