1.1 This test method covers two procedures for determining the cubic foot weight of crushed coal less than 11/2 in. (37 mm) in size, such as is charged into coke ovens, as follows:

1.1.1 Procedure A???The cone procedure for determining an uncompacted weight per cubic foot (cubic metre).

1.1.2 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.

1.2 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.

1.3 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.

1.4 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.
