Significance and Use
5.1 This test method provides for a separation of coal-associated sulfur into two commonly recognized forms: pyritic and sulfate. Organic sulfur is calculated by difference. Results obtained by the test method are used to serve a number of interests, including the evaluation of coal preparation and processing operations designed to reduce coal sulfur levels.
1.1 This test method applies to the determination of sulfate sulfur and pyritic sulfur in coal and calculates organic sulfur by difference. This test method is not applicable to coke or other carbonaceous materials.
1.2 The values stated in SI units are to be regarded as standard. Non-SI units, if provided, are considered informational and are contained within parentheses
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
