Sec. 92.133  Required information.

    (a) The required test data shall be grouped into the following two 
general categories:
    (1) Pre-test data. These data are general test data that must be 
recorded for each test. The data are of a more descriptive nature such 
as identification of the test engine, test site number, etc. As such, 
these data can be recorded at any time within 24 hours of the test.
    (2) Test data. These data are physical test data that must be 
recorded at the time of testing.
    (b) When requested, data shall be supplied in the format specified 
by the Administrator.
    (c) Pre-test data. The following shall be recorded, and reported to 
the Administrator for each test conducted for compliance with the 
provisions of this part:
    (1) Engine family identification (including subfamily 
identification, such as for aftertreatment systems).
    (2) Locomotive and engine identification, including model, 
manufacturer and/or remanufacturer, and identification number.

    (3) Locomotive and engine parameters, including fuel type, 
recommended oil type, exhaust configuration and sizes, base injection 
(ignition) timing, operating temperature, advance/retard injection 
(ignition) timing controls, recommended start-up and warm-up procedures, 
alternator generator efficiency curve.
    (4) Locomotive or engine and instrument operator(s).
    (5) Number of hours of operation accumulated on the locomotive or 
engine prior to beginning the testing.
    (6) Dates of most recent calibrations required by Secs. 92.115-
92.122.
    (7) All pertinent instrument information such as tuning (as 
applicable), gain, serial numbers, detector number, calibration curve 
number, etc. As long as this information is traceable, it may be 
summarized by system or analyzer identification numbers.
    (8) A description of the exhaust duct and sample probes, including 
dimensions and locations.
    (d) Test data. The physical parameters necessary to compute the test 
results and ensure accuracy of the results shall be recorded for each 
test conducted for compliance with the provisions of this part. 
Additional test data may be recorded at the discretion of the 
manufacturer or remanufacturer. Extreme details of the test measurements 
such as analyzer chart deflections will generally not be required on a 
routine basis to be reported to the Administrator for each test, unless 
a dispute about the accuracy of the data arises. The following types of 
data shall be required to be reported to the Administrator. The 
applicable Application Format for Certification will specify the exact 
requirements which may change slightly from year to year with the 
addition or deletion of certain items.
    (1) Date and time of day.
    (2) Test number.
    (3) Engine intake air and test cell (or ambient, as applicable) 
temperature.
    (4) For each test point, the temperature of air entering the engine 
after compression and cooling in the charge air cooler(s). If testing is 
not performed on a locomotive, the corresponding temperatures when the 
engine is in operation in a locomotive at ambient conditions represented 
by the test.
    (5) Barometric pressure. (A central laboratory barometer may be 
used: Provided, that individual test cell barometric pressures are shown 
to be within 0.1 percent of the barometric pressure at the 
central barometer location.)
    (6) Engine intake and test cell dilution air humidity.
    (7) Measured horsepower and engine speed for each test mode.
    (8) Identification and specifications of test fuel used.
    (9) Measured fuel consumption rate at maximum power.
    (10) Temperature set point of the heated continuous analysis system 
components (if applicable).
    (11) All measured flow rates, dilution factor, and fraction of 
exhaust diluted for diluted exhaust measurements (as applicable) for 
each test mode.
    (12) Temperature of the dilute exhaust mixture at the inlet to the 
respective gas meter(s) or flow instrumentation used for particulate 
sampling.
    (13) The maximum temperature of the dilute exhaust mixture 
immediately ahead of the particulate filter.
    (14) Sample concentrations (background corrected as applicable) for 
HC, CO, CO2, and NOX (and methane, NMHC, alcohols 
and aldehydes, as applicable) for each test mode. This includes the 
continuous trace and the steady-state value (or integrated value where 
required).
    (15) The stabilized pre-test weight and post-test weight of each 
particulate sample and back-up filter or pair of filters.
    (16) Brake specific emissions (g/BHP-hr) for HC, CO, NOX, 
particulate and, if applicable, CH3, NMHC, THCE, CH3OH, 
CH3CH2OH, CH2O and CH3CHO for each test mode.
    (17) The weighted brake specific emissions for HC, CO, 
NOX and particulate (g/BHP-hr) for the total test for the 
duty-cycle(s) applicable to the locomotive.
    (18) The smoke opacity for each test mode. This includes the 
continuous trace, the peak values and the steady-state value.
