Voorbeeldzinnen

1. The temperature of the inlet air to the engine (ambient air) shall be measured within 0,15 m upstream of the point of entry to the air cleaner, or, if no air cleaner is used, within 0,15 m of the air inlet horn.
2. The absolute temperature T of the air [1] at the inlet to the engine measured within 0,15 m upstream, of the point of entry to the air cleaner, or if no air cleaner is used, within 0,15 m of the air inlet horn, expressed in degrees Kelvin, and the atmospheric pressure ps, expressed in Kilopascals, shall be measured, and the atmospheric factor fa shall be determined according to paragraph 6.4.2.1 of Annex 10 to this Regulation which corresponds to the following provisions:
3. The A or C weighted sound pressure level produced by each horn sounded separately (or in a group if designed to sound simultaneously as a chord) shall be between 115dB and 123 dB when measured and verified in accordance with the method defined below. The 115dB sound pressure level shall be achieved when the system air pressure is at 5 bar and the 123dB sound pressure level shall not be exceeded when the system air pressure is at 9 bar.
