Standard Test Method for (Thiol Mercaptan) Sulfur in Gasoline, Kerosine, Aviation Turbine, and Distillate Fuels (Potentiometric Method)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of mercaptan sulfur in gasolines, kerosines, aviation turbine fuels, and distillate fuels containing from 0.0003 to 0.01 mass % of mercaptan sulfur. Organic sulfur compounds such as sulfides, disulfides, and thiophene, do not interfere. Elemental sulfur in amounts less than 0.0005 mass % does not interfere. Hydrogen sulfide will interfere if not removed, as described in .
1.2 The values in acceptable SI units are to be regarded as the standard. The values in parentheses are for information only.
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.
1.3 This test method provides an alternative to using a cadmium sulfate acid solution. (
1.4 This test method uses lead acetate test paper (
1.5 This test method shall not be used when the sample is a referee sample or when QA/QC protocols specify the test method as written. Instances in which they can be used may be instances of routine refinery control samples.
Significance and Use
Mercaptan sulfur has an objectionable odor, an adverse effect on fuel system elastomers, and is corrosive to fuel system components.
