Historical Standard: ASTM D4239-02 Standard Test Methods for Sulfur in the Analysis Sample of Coal and Coke Using High Temperature Tube Furnace Combustion Methods
SUPERSEDED (see Active link, below)
ASTM D4239
1. Scope
1.1 These test methods cover three alternative procedures using high-temperature tube furnace combustion methods for the rapid determination of sulfur in samples of coal and coke.
1.2 These test methods appear in the following order:
| Sections | |
| Method A High-Temperature Combustion Method with Acid Base Titration Detection Procedures | 6-9 |
| Method B High-Temperature Combustion Method with Iodimetric Titration Detection Procedures | 10-13 |
| Method C High-Temperature Combustion Method with Infrared Absorption Detection Procedures | 14-16 |
1.2.1 When automated equipment is used to perform any of the three methods of this test method, the procedures can be classified as instrumental methods. There are several manufacturers that offer to the coal industry equipment with instrumental analysis capabilities for the determination of the sulfur content of coal and coke samples.
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 and health practices and determine the applicability of regulatory limitations prior to use. See 7.8 and 15.2.
