Coal Producers and Users Invited to October Meetings on Standards
ASTM Subcommittee D05.23 on Sampling invites coal producers, users and related stakeholders to attend October 27 and 28 meetings on standards development in Cincinnati, Ohio. Contact chairman Bill Strang. Part of Committee D05 on Coal and Coke, the subcommittees six task groups develop and maintain guides, practices, and test methods for sampling of coal and coke derived from coal.
The subcommittee welcomes individuals involved with coal sampling systems to discuss the possible development of a Mechanical Coal Sampling Standard at the October meetings. D 2234 [D 2234/D 2234M, Standard Practice for Collection of a Gross Sample of Coal] is the basic sampling standard that we have, but it covers mechanical and manual sampling. The group wants to produce a stand-alone mechanical sampling standard, says Strang, a coal-preparation consultant, Big Stone Gap, Va.
A new stand-alone standard will greatly simplify the process for our standards users because everything they need will be housed in one neat package, he explains. Today, mechanical sampling system manufacturers and users must contend with the fact that D 2234 deals with the collection of only the gross sample (usually the primary increments) and D 2013, Standard Practice for Preparing Coal Samples for Analysis, covers the remainder of a typical mechanical sampling system.
At the October meetings, a subcommittee task group will discuss continued efforts to refine D 6518, Standard Practice for Bias Testing a Mechanical Coal Sampling System.
In 2003, the subcommittee successfully developed a proposed Standard Practice for Manual Sampling of Stationary Coal from Railroad Cars, Barges, Trucks, or Stockpiles, described on the ASTM Web site as Work Item WK160. Stakeholders can review WK160 online and direct comments to Strang. Go to www.astm.org/COMMITTEE/D05.htm, and click on Subcommittee D05.23.
The proposed standard covers procedures for obtaining a manual gross sample from beneath the surface of coal in railroad cars, barges, trucks, or stockpiles. These procedures will be used to provide gross samples for estimating the quality of the coal. According to Strang, This new standard provides improvements to and replaces D 4915 [Standard Guide for Manual Sampling of Coal from Tops of Railroad Cars], D 6315 [Standard Practice for Manual Sampling of Coal from Tops of Barges] , and D 6610 [Standard Practice for Manual Sampling Coal from Surfaces of a Stockpile].
In addition to these standards, the subcommittee also maintains:
D 346, Standard Practice for Collection and Preparation of Coke Samples for Laboratory Analysis;
D 4702, Standard Guide for Inspecting Crosscut, Sweep-Arm, and Auger Mechanical Coal-Sampling Systems for Conformance with Current ASTM Standards;
D 4916, Standard Practice for Mechanical Auger Sampling;
D 6543, Standard Guide to the Evaluation of Measurements Made by On-Line Coal Analyzers; and
D 6609, Standard Guide for Part-Stream Sampling of Coal.
