Division 5.1

In order to facilitate in-use compliance testing of hybrid electric vehicles — where an internal combustion engine cannot operate when the vehicle is stationary — the following information relating to the sound-pressure level measurements carried out in accordance with point 4.1 of Annex II for the motor vehicles in motion is referred to as in-use compliance reference data:

1. (a)

   gear (i) or, for vehicles tested with non-locked gear ratios, the position of the gear selector chosen for the test;

2. (b)

   position of the operating switch during measurement of the sound pressure level L_wot,(i) (if switch is fitted).

3. (c)

   pre-acceleration length l_PA in m;

4. (d)

   average vehicle speed in km/h at the beginning of the full throttle acceleration for tests in gear (i); and

5. (e)

   sound pressure level L_wot,(i) in dB(A) of the wide-open-throttle tests in gear (i), defined as the maximum of the two values resulting from averaging the individual measurement results at each microphone position separately.
