About This Item
ASTM D197 is the ASTM standard for the sampling and fineness test of pulverized coal, providing a technical basis for evaluating how coal is collected and how finely it has been ground. This matters because sample quality and particle fineness can influence test results, handling behavior, and product consistency. For laboratories, buyers, and plant personnel, ASTM D197 supports more reliable measurement and better comparison of pulverized coal material.
What is ASTM D197?
ASTM D197, titled Standard Test Method for Sampling and Fineness Test of Pulverized Coal, addresses two closely related checks: obtaining a representative sample and assessing the fineness of the pulverized coal. As a standard test method, it is intended to provide a consistent way to evaluate material condition rather than to define product acceptance by itself. In practice, it helps users compare results from one lot, process, or location to another with greater confidence.
Where is ASTM D197 used?
This standard is commonly used in coal testing and handling environments where pulverized coal must be sampled and its fineness assessed. That may include laboratories, quality control groups, and operational settings that manage coal preparation or combustion feed. ASTM D197 is especially relevant where material consistency matters and where a representative sample is needed to support testing, verification, or internal review of pulverized coal condition.
Why is ASTM D197 important?
ASTM D197 is important because sampling quality strongly affects the usefulness of any subsequent test result. A standard approach helps reduce uncertainty, improve repeatability, and support more dependable quality control decisions. For procurement, plant operations, and laboratory reporting, the method can help users document material condition in a consistent way. It also supports better communication between suppliers and buyers when pulverized coal performance or preparation quality is under review.
