Standard Test Method for Determining the Relative Degree of Oxidation in Bituminous Coal by Alkali Extraction
 N D5263

Annotation

This colorimetric test method describes the determination of the relative degree of oxidation by alkali extraction of coals that are high volatile A bituminous to low volatile bituminous in rank.

This test cannot be sensitive to thermally oxidized coal. It is intended for coals that may be oxidized as a result of weathering.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
