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: ID number; Manufacturer; Model Year; Engine family; Evaporative emissions family; Basic engine description (including displacement, number of cylinders, and catalyst usage); Engine maximum power rating and rated speed; Fuel system (including number of carburetors, number of carburetor barrels, fuel injection type, fuel tank(s) capacity and location, and number and size (volume and working capacity)) of evaporative control canisters, Engine code; Gross vehicle weight rating; Actual curb weight at zero miles; Actual road load at 50 mph; Transmission configuration; Axle ratio; Vehicle line; Odometer reading; Idle rpm; and Drive wheel tire pressure, as applicable.
(g) Indicated road load power absorption at 50 mph (80 km/hr) and dynamometer serial number. As an alternative to recording the dynamometer serial number, a reference to a vehicle test cell number may be used, provided the test cell records show the pertinent information.
(h) All pertinent instrument information such as tuning, gain, serial number, detector number and 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 and enclosure gas sample traces.
(j) Test cell barometric pressure and ambient temperature.
Note: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.
(k) Fuel temperatures as prescribed.
(l) For methanol-fueled vehicles:(1) Volume of sample passed through the methanol sampling system and the volume of deionized water in each impinger.
(2) The concentration of the GC analyses of the test samples (methanol).
(m) 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 hydrocarbons may be reported as a group.
(n) 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.
