# §86.155-98. Records required; refueling test.


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.**
- (d) **Instrument operated.**
- (e) **Operator.**
- (f) **Vehicle—** ID number, manufacturer, model year, engine family, evaporative/refueling emission family, refueling emission control system, refueling emissions canister continuous drive purge miles and number of UDDSs driven for non-integrated systems, fuel system (including fuel tank(s) capacity and location), basic engine description (including displacement, number of cylinders, turbocharger (if used), and catalyst usage), engine code, and odometer reading.
- (g) **All pertinent instrument information including nozzle and fuel delivery system description.** As an alternative, a reference to a vehicle test cell number may be used, with advance approval of the Administrator, provided test cell calibration records show the pertinent instrument information.
- (h) **Recorder charts—** Identify zero, span, and enclosure gas sample traces.
- (i) **Enclosure barometric pressure and ambient temperature—** 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.
- (j) **Temperatures—** Soak area; dispensed fuel, initial and final.
- (k) **Fuel dispensing rate(s).**
- (l) **Dispensed fuel volume.**
- (m) **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 methanol concentration in the reference sample and the peak area from the GC analysis of the reference sample.
  - (3) **The peak area of the GC analyses of the test samples (methanol).**
- (n) All additional information necessary for the calculations specified in [§ 86.156-98](/cfr/40/86.156-98.md).
