# Commission Regulation (EU) 2018/1832 of 5 November 2018 amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) 2017/1151 for the purpose of improving the emission type approval tests and procedures for light passenger and commercial vehicles, including those for in-service conformity and real-driving emissions and introducing devices for monitoring the consumption of fuel and electric energy (Text with EEA relevance), Annex V

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

Annex IX to Regulation (EU) 2017/1151 is amended as follows:
(1) in Section A, point 3. is replaced by the following:
‘3.
Technical data on fuels for testing fuel cell vehicles
Type: Hydrogen for fuel cell vehicles
The hydrogen fuel index is determined by subtracting the “total non-hydrogen gases” in this table, expressed in mole per cent, from 100 mole per cent.
Total hydrocarbons include oxygenated organic species. Total hydrocarbons shall be measured on a carbon basis (μmolC/mol). Total hydrocarbons may exceed 2 μmol/mol due only to the presence of methane, in which case the summation of methane, nitrogen and argon shall not exceed 100 μmol/mol.
As a minimum, total sulphur compounds include H2S, COS, CS2 and mercaptans, which are typically found in natural gas.
Total halogenated compounds include, for example, hydrogen bromide (HBr), hydrogen chloride (HCl), chlorine (Cl2), and organic halides (R-X).
Test method shall be documented.
For the constituents that are additive, such as total hydrocarbons and total sulfur compounds, the sum of the constituents are to be less than or equal to the acceptable limit.
