(Test Method)Standard Test Method for Sulfur Content in Carbon Black Feedstock Oils
Standard Test Method for Sulfur Content in Carbon Black Feedstock Oils
SIGNIFICANCE AND USE
Measuring the total sulfur content of feedstock oil is often a necessary component in calculations for sulfur dioxide emissions.
The carbon black industry measures sulfur content of feedstock oils along with sulfur content of carbon black products per Test Method D1619 in calculations to determine sulfur dioxide emissions for compliance with governmental reporting requirements.
SCOPE
1.1 This test method covers the instrumental determination of sulfur content in samples of carbon black feedstock oils. Values obtained represent the total sulfur content.
1.2 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.
1.3 The results of these tests can be expressed as mass % sulfur.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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.
