(Practice)Standard Practice for Sampling of Green Petroleum Coke
Standard Practice for Sampling of Green Petroleum Coke
SCOPE
1.1 This practice primarily references Practice D2234/D2234M and applies its sampling principles to green petroleum coke. Green petroleum coke is typically more homogeneous than coal and this practice provides specific guidance for the application of D05.05 coal standards to the sampling of green petroleum coke.
1.1.1 Practice D2234/D2234M references the four conditions of collecting sample increments: Condition A (Stopped Belt Cut), Condition B (Full-stream Cut), Condition C (Part-stream Cut), and Condition D (Stationary Sampling). This practice directs the user to the appropriate coal standard to apply to each condition, as well as key considerations.
1.2 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.
1.3 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.

INTRODUCTION
Green petroleum coke is a byproduct of certain oil refining technologies but has multiple uses, such
as a solid mineral fuel or a key constituent of making anodes. The chemical and physical
characteristics of green petroleum coke, particularly the moisture content, are not always distributed
equally in the different sized particles. As such, the sampling of green petroleum coke must follow the
general sampling principals of capturing the particle size distribution of the consignment into the gross
sample that is collected to represent it.
Green petroleum coke sampling has relied on the sampling standards for Coal and Coke under
ASTM Subcommittee D05.05 for guidance on how to collect and prepare samples, in particular,
Practice D2234/D2234M for the Collection of a Gross Sample of Coal, Practice D2013/D2013M for
the Preparation of Coal Samples for Analysis, and Practice D346 for the Collection and Preparation
of Coke Samples for Laboratory Analysis have been used, among others. With the growing use of
mechanical sampling equipment, Practice D7430 for the Mechanical Sampling of Coal has been added
to the mix. The above cited standards are useful, but do not account for some of the unique
characteristics of petroleum coke, which has led to widespread confusion as to which parts are
applicable, especially Practice D346, which is really used for coke made from coal and not from
petroleum refining.
This practice gives guidelines for the user on how to sample green petroleum coke. The intent is not
to write a standalone standard for green petroleum coke but to direct the user as to how to apply the
D05.05 coal standards already in existence.
