NOTE：*1 If IAT tuning is used to qualify the engine as fit-for-use, the temperature can be adjusted within ±22°C from the base temperature specified for the prevailing barometric pressure, and this temperature shall then be maintained within ±1°C when CR or KI results used for octane determination on each fuel are recorded. See ASTM D2699 for details. |
