Full title and description

St ASTM D3175-20 — Standard Test Method for Volatile Matter in the Analysis Sample of Coal and Coke. This standard specifies the laboratory procedures to determine volatile matter (the gaseous products exclusive of moisture vapor) released from an analysis sample of coal or coke under controlled heating conditions; a Russian-language version/translation is sometimes offered by third‑party distributors.

Abstract

ASTM D3175-20 defines empirical procedures to measure mass loss attributable to volatile matter in coal and coke analysis samples. The method describes sample handling and two alternative procedures to accommodate differences in sample behavior (including swelling and popping), instrumentation and reporting conventions, and includes notes on units, corrections for moisture and ash basis conversions, and safety considerations.

Scope

This test method covers the determination of volatile matter (gaseous products exclusive of moisture vapor) from an analysis sample of coal or coke. It is empirical in nature, provides SI units as standard, and describes two procedures to permit testing of different sample types (including strongly swelling coals). It does not replace safety responsibility of the user.

Key topics and requirements

• Definition and significance of volatile matter for rank classification, coke yield and combustion behavior.
• Sample preparation and correction for moisture (reference to ASTM D3173/D3173M for moisture determination).
• Two alternative heating/procedure options to account for sample swelling/popping characteristics.
• Use of specified crucibles, lids and temperature controls (rigidly controlled heating conditions) and calculation of mass loss.
• Units, basis conversions (as‑received, dry, ash‑free) and reporting conventions.
• Precision, bias statements and references to interlaboratory study practices where applicable.
• Safety, health and environmental practice notes—users must establish applicable procedures before testing.

Typical use and users

Used by coal and coke testing laboratories, quality control departments in mining and power generation, coke producers, research institutions and regulatory or procurement bodies to characterize fuel properties, support sales/purchase specifications, estimate coke yields, and classify coal rank. Laboratory technicians, analytical chemists and process engineers are the primary users.
