ASTM D5003/D5003M-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Hardgrove Grindability Index (HGI) of Petroleum Coke
This standard is issued under the fixed designation D5003;D5003/D5003M; the number immediately following the designation indicates
the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Introduction of petroleum coke into the coal market in recent years has necessitated the use of many
of the test methods for coal so like data would be available for comparison and blending purposes. Test
Method D409 does not cover petroleum coke in its scope and its statements of precision and bias do
not include petroleum coke. This test method provides the procedures and precision and bias data for
the hardgrove grindability index (HGI) of petroleum coke. Use of this test method or Test Method
D409 produces the same value for the sample of petroleum coke being analyzed.
1. Scope*
1.1 This test method covers the determination of the hardgrove grindability index (HGI) of those petroleum cokes that contain no
dedusting additive. The procedure for this test method is the same as in Test Method D409. Sections of this test method contain
the significance and use of the HGI of petroleum coke, preliminary sample preparation procedures, and procedure and precision
and bias data specific to petroleum coke.
NOTE 1—The size consistency (particle size distribution) of fluid petroleum coke is generally 100 % passing a 6.73 mm (No. 3) 6.7 mm [0.265 in.] sieve
and greater than 80 % passing a 2.00 mm (No. 10)2 mm [No. 10] sieve. Much of fluid cokes will pass a 0.59 mm (No. 30)600 μm [No. 30] sieve. Because
of this fineness the HGI value is related to the coarser particles in fluid coke and large samples are required to prepare sufficient material of the correct
particle size for Test Method D409.
1.2 The values stated in either SI units or inch-pound units are to be regarded as standard. No other units of measurement are
included in this separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Exception—Hardgrove grindability index is unitless.
1.3 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.
1.4 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.
