Title
Standard Test Method for Cubic Foot Weight of Crushed Bituminous Coal
ASTM International
Publication Date:
Oct 1, 2007
Scope:
This test method covers two procedures for determining the cubic
foot weight of crushed coal less than 1½ in. (37 mm) in size, such
as is charged into coke ovens, as follows:
Procedure A—The cone procedure for determining an
uncompacted weight per cubic foot (cubic metre).
Procedure B—The dropped-coal procedure for determining
a compacted weight per cubic foot (cubic metre), comparable to
actual bulk densities attained in coke ovens.
This test method is not applicable to the testing of powdered
coal as used in boiler plants, nor to the determination of weights
per cubic foot of coal in storage piles.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard. Mass may be expressed in metric
values.
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.
