In the case of a compressed hydrogen-fuelled vehicle:
5.5.2.1                                  The hydrogen leakage rate (VH2) determined in accordance with either, paragraph 4. of Annex 6 for hydrogen, or paragraph 5. of Annex 6 for helium, shall not exceed an average of 118 NL per minute for the time interval, Δt minutes, after the crash;
5.5.2.2                    The gas (hydrogen or helium as applicable) concentration by volume in air values determined for the passenger and luggage compartments in accordance with paragraph 6. of Annex 6, shall not exceed 4.0 per cent for hydrogen or 3.0 per cent for helium, at any time throughout the 60 minute post‑crash measurement period; [7] and
5.5.2.3                    The container(s) (for hydrogen storage) shall remain attached to the vehicle at a minimum of one attachment point.

6.                                              Modification of the vehicle type and extension of approval
6.1.                                           Every modification, affecting the design characteristics of the vehicle type identified in paragraph 2.26. (a) to (i) above, shall be brought to the attention of the Approval Authority which approved the vehicle type. The Approval Authority may then either:
6.1.1                                       Consider that the modifications made will not have an appreciable adverse effect on the vehicle‑to‑pole side impact performance and grant an extension of the approval; or
6.1.2                                       Consider that the modifications made could adversely affect the vehicle‑to‑pole side impact performance and require further tests or additional checks before granting an extension of the approval.
6.2.                                           Provided there is otherwise no conflict with the provisions of paragraph 6.1. above, the approval shall be extended to cover all the other variants of the vehicle type for which the sum of the unladen vehicle mass and the rated cargo and luggage mass is not more than 8 per cent greater than that of the vehicle used in the approval test.
6.3.                                           A notice of extension or refusal of approval, specifying the alteration(s), shall be communicated by the Approval Authority to the other Contracting Parties to the Agreement which apply this Regulation, using the procedure specified in paragraph 4.4. above.
6.4.                                           The Approval Authority shall assign a serial number to each extension, to be known as the extension number.

7.                                              Conformity of production
The conformity of production procedures shall comply with those set out in  Appendix 2 of the Agreement (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements.
7.1.                                           Every vehicle approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set out in paragraph 5. above.
7.2.                                           The holder of the approval shall ensure that for each type of vehicle at least the tests concerning the taking of measurements are carried out.
7.3.                                           The authority which has granted type approval may at any time verify the conformity control methods
