This test method covers the instrumental determination of sulfur content in samples of carbon black feedstock oils. Values obtained represent the total sulfur content. Two analysis methods are available for use:
Test Method A: High-Temperature Combustion With Infrared Absorption Detection Procedures
Test Method B: X-Ray Fluorescence Sections 13 – 17
This test method is applicable to carbon black feedstock oils derived from petroleum, coal, and other sources which include fuel oils, residues, tars, pitches, reclaimed oils, and similar materials that are normally handled as liquids. This test method is applicable to products typically containing 0 to 5 mass % sulfur.
The results of these tests can be expressed as mass % sulfur.
