Standard Test Methods for
Evaluation of Engine Oils in A High-Speed, Single-Cylinder
Diesel Engine —1K Procedure (0.4 % Fuel Sulfur) and 1N

Procedure (0.04 % Fuel Sulfur)
This standard is issued under the fixed designation D 6750; 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.
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 (TCM) provides reference
oils and an assessment of the test results obtained on those oils by the laboratory (seeAnnexA16). By
this means, the laboratory will know whether its use of the test methods gives results statistically
similar to those obtained by other laboratories. Furthermore, various agencies require that a laboratory
utilizes 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
theTMC. In addition, theTMC may issue supplementary memoranda related to the test methods, also
obtainable from the TMC.
