ANNEX VSupplementary provisions
ANNEX V 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 Characteristics Units Limits Test Method minimum maximum Hydrogen fuel index ( 1 ) % mole 99,97 Total non-hydrogen gases μmol/mol 300 Maximum concentration of individual contaminants Water (H 2 O) μmol/mol 5 ( 5 ) Total hydrocarbons ( 2 ) (Methane basis) μmol/mol 2 ( 5 ) Oxygen (O 2 ) μmol/mol 5 ( 5 ) Helium (He) μmol/mol 300 ( 5 ) Total Nitrogen (N 2 ) and Argon (Ar) ( 2 ) μmol/mol 100 ( 5 ) Carbon dioxide (CO 2 ) μmol/mol 2 ( 5 ) Carbon monoxide (CO) μmol/mol 0,2 ( 5 ) Total sulfur compounds ( 3 ) (H 2 S basis) μmol/mol 0,004 ( 5 ) Formaldehyde (HCHO) μmol/mol 0,01 ( 5 ) Formic acid (HCOOH) μmol/mol 0,2 ( 5 ) Ammonia (NH 3 ) μmol/mol 0,1 ( 5 ) Total halogenated compounds ( 4 ) (Halogenate ion basis) μmol/mol 0,05 ( 5 ) 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. ( 1 ) 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. ( 2 ) 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. ( 3 ) As a minimum, total sulphur compounds include H 2 S, COS, CS 2 and mercaptans, which are typically found in natural gas. ( 4 ) Total halogenated compounds include, for example, hydrogen bromide (HBr), hydrogen chloride (HCl), chlorine (Cl 2 ), and organic halides (R-X). ( 5 ) Test method shall be documented.’
