(a) This part describes the procedures that apply to testing we
require for the following engines or for vehicles using the following
engines:
(1) Model year 2010 and later heavy-duty highway engines we regulate
under 40 CFR part 86. For earlier model years, manufacturers may use the
test procedures in this part or those specified in 40 CFR part 86,
subpart N, according to Sec. 1065.10.
(2) Land-based nonroad diesel engines we regulate under 40 CFR part
1039.
(3) Large nonroad spark-ignition engines we regulate under 40 CFR
part 1048.
(4) Vehicles we regulate under 40 CFR part 1051 (such as snowmobiles
and off-highway motorcycles) based on engine testing. See 40 CFR part
1051, subpart F, for standards and procedures that are based on vehicle
testing.
(5) Stationary compression-ignition engines certified using the
provisions of 40 CFR part 1039, as indicated under 40 CFR part 60,
subpart IIII, the standard-setting part for these engines.
(b) The procedures of this part may apply to other types of engines,
as described in this part and in the standard-setting part.
(c) This part is addressed to you as a manufacturer, but it applies
equally to anyone who does testing for you.
(d) Paragraph (a) of this section identifies the parts of the CFR
that define emission standards and other requirements for particular
types of engines. In this part, we refer to each of these other parts
generically as the ``standard-setting part.'' For example, 40 CFR part
1051 is always the standard-setting part for snowmobiles.
(e) Unless we specify otherwise, the terms ``procedures'' and ``test
procedures'' in this part include all aspects of engine testing,
including the equipment specifications, calibrations, calculations, and
other protocols and procedural specifications needed to measure
emissions.
(f) For vehicles subject to this part and regulated under vehicle-
based standards, use good engineering judgment to interpret the term
``engine'' in this part to include vehicles where appropriate.
(g) For additional information regarding these test procedures,
