6.3.4 Test fuels

  6.3.4.1 Generally all emission measurements shall be carried out with the engine running on marine diesel fuel oil of an ISO 8217, 1996, DM-grade.

  6.3.4.2 To avoid an unacceptable burden to the shipowner, the measurements for confirmation tests or re-surveys may, based on the recommendation of the engine manufacturer and the approval of the Administration, be allowed with an engine running on heavy fuel oil of an ISO 8217, 1996, RM-grade. In such a case the fuel-bound nitrogen and the ignition quality of the fuel may have an influence on the NOx emissions of the engine.
