Standard Test Method for Bulk Density of Densified Particulate Biomass Fuels

SIGNIFICANCE AND USE
The test procedures described in this test method can be used to determine the bulk density (or bulk specific weight) of any densified particulate biomass fuel meeting the requirements specified in this test method.
SCOPE
1.1 This test method covers the procedure for the determination of bulk density (or bulk specific weight) of densified particulate biomass fuels with a maximum particle volume of 16.39 cm3  (1 in. 3).
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
