Standard Test Method for
(Thiol Mercaptan) Sulfur in Gasoline, Kerosine, Aviation
Turbine, and Distillate Fuels (Potentiometric Method)1

This standard is issued under the fixed designation D 3227; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

1. 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 9.2.

1.2 The values in acceptable SI units are to be regarded as
the standard. The values in parentheses are for information
only.

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. For specific hazard
statements, see Sections 6, 8, and 9.
