Procedure (0.04 % Fuel Sulfur)
This standard is issued under the fixed designation D6750; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The test methods described in this standard can be used by any properly equipped laboratory

without outside assistance. However, the ASTM Test Monitoring Center (TMC) provides reference

this means, the laboratory will know whether its use of the test methods gives results statistically
similartothoseobtainedbyotherlaboratories.Furthermore,variousagenciesrequirethatalaboratory
uses the TMC services in seeking qualification of oils against specifications. For example, the U.S.
Army has such a requirement in some of its engine oil specifications.
Accordingly, these test methods are written for those laboratories that use the TMC services.
Laboratories that choose not to use these services may ignore those portions of the test methods that
refer to the TMC.
These test methods may be modified by Information Letters issued periodically by the TMC after
the publication of this edition of the standard to become part of it. These letters are obtainable from
