[1]        Insert new clause 5.4 which reads:
“5.4     For the purposes of the Type VI test specified in paragraph 5.3.5 of Appendix A, flex fuel ethanol vehicles that meet the applicable hydrocarbon (HC) emission limit for N1 Class III vehicles in column L2 of the table to paragraph 5.3.5.2 of Appendix A when tested on the ethanol (E75) reference fuel in paragraph 2 of Annex 10 of Appendix A, shall be deemed to meet the HC emission limit for this test on ethanol.”
 
[2]        Insert new clause 5.5 which reads:
“5.5.    In Table A to paragraph 5.2 of Appendix A, footnote 3 is amended to read “The ethanol (E75) reference fuel specified in paragraph 2 of Annex 10 of Appendix A shall be used for this test.”
[3]        Insert new clause 5.6 which reads:
“5.6     The Ethanol (E75) reference fuel specification in paragraph 2 of Annex 10 of Appendix A is amended to read:

  1     The values quoted in the specifications are "true values". In establishment of their limit values the terms of ISO 4259 Petroleum products - Determination and application of precision data in relation to methods of test have been applied.  When fixing a minimum value, a minimum difference of 2R above zero was taken into account.  When fixing a maximum and minimum value, the minimum difference used was 4R (R = reproducibility).  Notwithstanding this procedure, which is necessary for technical reasons, fuel manufacturers shall aim for a zero value where the stipulated maximum value is 2R and for the mean value for quotations of maximum and minimum limits.  Where it is necessary to clarify whether fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
2     In cases of dispute, the procedures for resolving the dispute and interpretation of the results based on test method precision, described in EN ISO 4259 shall be used.
3     In cases of national dispute concerning sulphur content, either EN ISO 20846 or EN ISO 20884 shall be called up similar to the reference in the national annex of EN 228.
4     The actual sulphur content of the fuel used for the Type VI Test shall be reported.
5     The unleaded petrol content can be determined as 100 minus the sum of the percentage content of water and alcohols.
6     There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
7     Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.”


 
[4]        Insert new clause 5.7 which reads:
 
            “5.7     For the purposes of calculating the Lambda value when tested at ‘high idle speed’ in accordance with Paragraph 5.3.7.3. of Appendix A on the ethanol (E75) reference fuel in paragraph 2 of Annex 10 of Appendix A:
 
-           the Atomic ratio of hydrogen to carbon shall be 2.61; and
-           the Atomic ratio of oxygen to carbon shall be 0.329.”
 
[5]        Insert new clause 5.8 which reads
 
            “5.8      For the purposes of determining the total mass of Hydrocarbons emitted in accordance with paragraph 6.6.2. of Annex 4a of Appendix A, when tested on the ethanol (E75) reference fuel in paragraph 2 of Annex 10 of Appendix A, the density shall be 0.886 g/l.”
 
[6]       Insert new clause 5.9 which reads:
 
            “5.9      For the purposes of determining the correction for dilution air concentration in accordance with paragraph 6.6.4 of Annex 4a of Appendix A, when tested on the ethanol (E75) reference fuel in paragraph 2 of Annex 10 of Appendix A, the dilution factor shall be calculated as follows:
