ASTM D3173/D3173M is the ASTM standard titled Standard Test Method for Moisture in the Analysis Sample of Coal and Coke. It provides a consistent way to determine moisture in prepared analysis samples, which is important because moisture can affect test results, reporting, and comparison between materials. For laboratories, buyers, and quality teams, this standard supports more reliable coal and coke evaluation and helps align testing practice with a recognized technical document.

Purpose of ASTM D3173/D3173M

The purpose of ASTM D3173/D3173M is to define a standard test method for measuring moisture in the analysis sample of coal and coke. As a moisture-focused test method, it helps establish a common basis for laboratory work and reporting. This matters when results need to be comparable across different samples, facilities, or testing programs. By using ASTM D3173/D3173M, organizations can better support consistency in sample evaluation and quality-related decisions.

Common use cases of ASTM D3173/D3173M

This standard is commonly used in coal and coke testing workflows where analysis samples must be evaluated for moisture content before further reporting or interpretation. It is relevant in laboratory settings, quality control programs, and procurement-related testing where consistent moisture measurement may affect material assessment. ASTM D3173/D3173M is also useful when comparing results from different analysis samples and when a recognized ASTM standard is needed for documentation or compliance-focused work.

Why ASTM D3173/D3173M matters

ASTM D3173/D3173M matters because moisture can influence the reliability and comparability of coal and coke test data. A standard method helps reduce variation between laboratories and supports clearer technical communication. In practice, this can improve confidence in quality control, material acceptance, and product evaluation. For organizations that rely on consistent analysis results, ASTM D3173/D3173M provides a practical reference for using a recognized testing approach.
