  "text": "Where the engine inlet air temperature sensor is being used to estimate ambient air temperature the nominal offset between the two measurement points shall be evaluated for an engine type or engine family. Where used, the measured intake air temperature shall be adjusted by an amount equal to the nominal offset to estimate ambient temperature for an installation using the specified engine type or engine family.\nThe evaluation of the offset shall be made using good engineering judgement based on technical elements (calculations, simulations, experimental results, data etc.) including:\n(a) the typical categories of non-road mobile machinery into which the engine type or engine family will be installed; and,\n(b) the installation instructions provided to the OEM by the manufacturer.\nA copy of the evaluation shall be made available to the approval authority upon request.",
