# Commission Regulation (EC) No 692/2008 of 18 July 2008 implementing and amending Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (Text with EEA relevance), Division 1: Technical data on fuels for testing vehicles with positive-ignition engines

Extent: E+W+S+N.I.

Type: Petrol (E5)
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 and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account; in fixing a maximum and minimum value, the minimum difference is 4R (R = reproducibility). Notwithstanding this measure, which is necessary for technical reasons, the manufacturer of fuels shall nevertheless aim at a zero value where the stipulated maximum value is 2R and at the mean value in the case of quotations of maximum and minimum limits. Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
The fuel may contain oxidation inhibitors and metal deactivators normally used to stabilise refinery gasoline streams, but detergent/dispersive additives and solvent oils shall not be added.
Ethanol meeting the specification of EN 15376 is the only oxygenate that shall be intentionally added to the reference fuel.
The actual sulphur content of the fuel used for the Type 1 test shall be reported.
There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.

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.
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.
The actual sulphur content of the fuel used for the Type 1 test shall be reported.
The unleaded petrol content can be determined as 100 minus the sum of the percentage content of water and alcohols
There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.

This method may not accurately determine the presence of corrosive materials if the sample contains corrosion inhibitors or other chemicals which diminish the corrosivity of the sample to the copper strip. Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited.

The hydrogen fuel index is determined by subtracting the total content of non-hydrogen gaseous constituents listed in the table (Total gases), expressed in mole percent, from 100 mole percent. It is less than the sum of the maximum allowable limits of all non-hydrogen constituents shown in the Table.
The value of total gases is summation of the values of the non-hydrogen constituents listed in the table, except the particulates.
