Division 4 INTERPRETATION OF RESULTS

United Kingdom

Original text. Later amendments are not shown.

Every individual noise measurement shall be evaluated.

The sound level of every specified measurement point shall not exceed the limits given below:

Lkj ≤ LASEP_k.j + x

With:

x

  • 3 dB(A) for vehicle with a non-lockable automatic transmission or non-lockable CVT

    • x

  • 2 dB(A) + limit value – Lurban of Annex II for all other vehicles

    • If the measured sound level at a point exceeds the limit, two additional measurements at the same point shall be carried out to verify the measurement uncertainty. The vehicle is still in compliance with ASEP, if the average of the three valid measurements at this specific point fulfils the specification.
