40 CFR 86.337-79 - Information.
The following information, as applicable, shall be recorded for each test:
(a) Engine description and specification. A copy of the information specified in this paragraph must accompany each engine sent to the Administrator for compliance testing. The manufacturer need not record the information specified in this paragraph for each test if the information, with the exception of paragraphs (a) (3), (12), and (13), is included in the manufacturer's Part I.
(18) Maximum exhaust system back pressure at 2000 rpm, if applicable (gasoline-fueled engines only).
(b) Test data; general. This information may be recorded at any time between 4 hours prior to the test and 4 hours after the test.
(5) Number of hours of operation accumulated on the engine prior to beginning the warm-up portion of the test.
(8) All pertinent instrument information such as tuning, gain, serial numbers, detector number, calibration curve numbers, etc. As long as this information is traceable, it may be summarized by system number or analyzer identification numbers.
(5) Engine intake humidity, pre-test for gasoline-fueled engines, pre-test segment for Diesel engines with non-conditioned air supply systems.
(8) Recorder chart or equivalent. Identify for each test (test segment for Diesel engines) zero traces for each range used, and span traces for each range used.
(1) Recorder chart or equivalent. Identify for each test mode the emission concentration traces and the associated analyzer range(s). The start and finish of each test.
(4) Record engine torque and engine rpm continuously with a chart recorder or equivalent recording device.
(7) Fuel flow for each mode. If the fuel flow measurement is a volume measurement system, record the fuel temperature in the measurement system for fuel density corrections to the mass flow rate. If the fuel temperature is within 3 °C (5.4 °F) of the calibration temperature, no density correction is required.
(2) Recorder chart or equivalent. Identify the zero traces for each range used and the span traces for each range used.
