6.3.9.3 If the number of measuring points on board is different than those on the test bed, the measuring points and the weighting factors shall be in accordance with the recommendations of the engine manufacturer and approved by the Administration.
6.3.10 Calculation of gaseous emissions
the calculation procedure specified in chapter 5 shall be applied, taking into account the special requirements of this simplified measurement procedure.
6.3.11 Allowances
6.3.11.1 Due to the possible deviations when applying the simplified measurement procedures of this chapter on boards ship, as allowance of 10% of the applicable limit value may be accepted for confirmation tests and periodical and intermediate surveys only.
6.3.11.2 In no case shall an allowance be granted for possible deviations of measurements if an initial survey is carried out on board a ship without any valid pre-certification test. If such an exception its the test procedure is, however, approved by the Administration, the test on board shall be carried out, regarding accuracy and permissible deviations, under the provisions of chapters.
6.3.11.3 The NOx emission of an engine may vary depending on the ignition quality of the fuel and the fuel bound nitrogen. If there is insufficient information available on the influence of the ignition quality on the NOx formation during the combustion process and the fuel bound nitrogen conversion rate also depends on the engine efficiency, an allowance of 10% may be granted for an on-board test run carried out on a RM-grade fuel (ISO 8217. 1996). The fuel oil used shall be analysed for its composition of carbon, hydrogen, nitrogen, sulphur and, to the extend given in ISO 8217. 1996, any additional components necessary for a clear specification of the fuel.
63.11.4 In no case shall the total granted allowance for hosts the simplification of measurements on board and the use of heavy fuel oil of an ISO 8217. 1996, RM-grade fuel exceed 15% of the applicable limit value.
