40 CFR 86.542-90 - Records required.
The following information shall be recorded with respect to 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) Instrument operator.
(e) Driver or operator.
(f)Vehicle: Make, Vehicle identification number, Model year, Transmission type, Odometer reading at initiation of preconditioning, Engine displacement, Engine family, Emission control system, Recommended idle RPM, Nominal fuel tank capacity, Inertial loading, Actual curb mass recorded at 0 kilometers, and Drive wheel tire pressure.
(g)Dynamometer serial number: As an alternative to recording the dynamometer serial number, a reference to a vehicle test cell number may be used, with the advance approval of the Administrator, provided the test cell records show the pertinent instrument information.
(h) All pertinent instrument information such as tuning-gain-serial number-detector number-range. As an alternative, a reference to a vehicle test cell number may be used, with the advance approval of the Administrator, provided test cell calibration records show the pertinent instrument information.
(i) Recorder Charts: Identify zero, span, exhaust gas, and dilution air sample traces.
(j) Test cell barometric pressure, ambient temperature and humidity.
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.
(l) Pressure of the mixture of exhaust and dilution air entering the CVS metering device, the pressure increase across the device, and the temperature at the inlet. The temperature may be recorded continuously or digitally to determine temperature variations.
(m) The number of revolutions of the positive displacement pump accumulated during each test phase while exhaust samples are being collected. The number of standard cubic meters metered by a critical flow venturi during each test phase would be the equivalent record for a CFV-CVS.
(n) The humidity of the dilution air.
If conditioning columns are not used (see §§ 86.522 and 86.544) this measurement can be deleted. If the conditioning columns are used and the dilution air is taken from the test cell, the ambient humidity can be used for this measurement.
(o) The driving distance for each of the three phases of test, calculated from the measured roll or shaft revolutions.
(p) Additional required records for methanol-fueled vehicles:
(1) Specification of the methanol fuel, or fuel mixtures, used during testing.
(2) Volume of sample passed through the methanol sampling system and the volume of deionized water in each impinger.
(3) The methanol calibration information from the GC standards.
(4) The concentration of the GC analyses of the test samples (methanol).
(5) Volume of sample passed through the formaldehyde sampling system.
(6) The formaldehyde calibration information from the HPLC standards.
(7) The concentration of the HPLC analysis of the test sample (formaldehyde).
(q)Additional required records for natural gas-fueled vehicles. Composition, including all carbon containing compounds; e.g. CO2, of the natural gas-fuel used during the test. C1 and C2 compounds shall be individually reported. C3 and heavier hydrocarbons and C6 and heavier compounds may be reported as a group.
(r)Additional required records for liquefied petroleum gas-fueled vehicles. Composition of the liquefied petroleum gas-fuel used during the test. Each hydrocarbon compound present, through C4 compounds, shall be individually reported. C5 and heavier hydrocarbons may be reported as a group.
