Organization: ASTM
Publication Date: 1 November 2020
Status: active
Page Count: 7
ICS Code (Coals): 73.040
scope:

This test method covers two procedures for determining the bulk density of crushed coal less than 37.5 mm [1.5 in.] in size, such as is charged into coke ovens, as follows:

Procedure A-The cone procedure for determining an uncompacted bulk density.

Standard Method-Procedure employs the use of a 115 mm [4.5 in.] chute opening and a measuring box having dimensions of 305 mm x 305 mm x 305 mm [12.0 in. x 12.0 in. x 12.0 in.].

Alternate Method-Procedure employs the use of a 203 mm [8.0 in.] chute opening and a measuring box having dimensions of 203 mm x 203 mm x 305 mm [8.0 in. x 8.0 in. x 12.0 in.] for coals with a total moisture greater than 7 %.

Procedure B-The dropped-coal procedure for determining a compacted bulk density, 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 the bulk density of coal in storage piles.

Units-The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
