Sec. 1065.605  Required records.

    Retain the following information for each test:
    (a) Test number.
    (b) System or device tested (brief description).
    (c) Date and time of day for each part of the test schedule.
    (d) Test results.
    (e) Operator's name.
    (f) Engine: ID number, manufacturer, model year, emission standards, 
engine family, basic engine description, fuel system, engine code, and 
idle speed, as applicable.
    (g) Dynamometer: Dynamometer identification, records to verify 
compliance with the duty cycle requirements of the test.
    (h) Gas analyzers: Analyzer bench identification, analyzer ranges, 
recordings of analyzer output during zero, span, and sample readings.
    (i) Recorder charts: Test number, date, identification, operator's 
name, and identification of the measurements recorded.
    (j) Test cell barometric pressure, ambient temperature, and humidity 
as required. (Some test systems may require continuous measurements; 
others may require a single measurement, or measurements before and 
after the test.)
    (k) Temperatures: Records to verify compliance with the ambient 
temperature requirements throughout the test procedure.
    (l) CFV-CVS: Total dilute exhaust volume (Vmix) for each phase of 
the exhaust test.
    (m) PDP-CVS: Test measurements for calculating the total dilute 
exhaust volume (Vmix), and the Vmix for each phase of the exhaust test.
    (n) The humidity of the dilution air.
    Note: If you do not use conditioning columns, this measurement is 
not necessary. If you use conditioning columns and take the dilution air 
from the test cell, you may use the ambient humidity for this 
measurement.
