ASTM D3175-17
(Test Method)Standard Test Method for Volatile Matter in the Analysis Sample of Coal and Coke
Standard Test Method for Volatile Matter in the Analysis Sample of Coal and Coke
SIGNIFICANCE AND USE
5.1 Volatile matter, when determined as herein described, can be used to establish the rank of coals, to indicate coke yield on carbonization process, to provide the basis for purchasing and selling, or to establish burning characteristics.
SCOPE
1.1 This test method covers the determination of the gaseous products, exclusive of moisture vapor, as volatile matter in the analysis sample of coal or coke from coal.
1.2 The test method for the determination of volatile matter is empirical.
1.3 Units—The values stated in SI units are to be regarded as standard.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
