security accreditation decisions shall, following the process defined in the security accreditation strategy, be based on local security accreditation decisions taken by the respective national security accreditation authorities of the Member States.

(4) It is desirable to take into account the technical requirements adopted by the UN Economic Commission for Europe in its Regulation No 30 (‘Uniform provisions concerning the approval of pneumatic tyres for motor vehicles and their trailers’), as amended , in its Regulation No 54 (‘Uniform provisions concerning the approval of pneumatic tyres for commercial vehicles and their trailers’) , in its Regulation No 64 (‘Uniform provisions concerning the approval of vehicles equipped with temporary-use spare wheels/tyres’), as amended , and in its Regulation No 117 (‘Uniform Provisions Concerning the Approval Of Tyres With Regard To Rolling S ...[+++]ound Emissions And To Adhesion On Wet Surfaces’), as amended , which are annexed to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement) .

3. Without prejudice to paragraphs 1 and 2 of this Article, and subject to the entry into force of the implementing measures adopted pursuant to Article 12(1), if a manufacturer so requests, national authorities may not, on grounds relating to hydrogen propulsion, refuse to grant EC type-approval, or national type-approval, for a new type of vehicle or EC type-approval or national type approval for a new type of hydrogen component or system, or prohibit the registration, sale or entry into service of a new vehicle or prohibit the sale or entry into service of a new hydrogen component or system, where the vehicle, component or system concerned complies with the requirements set out in this Regulation ...[+++] and its implementing measures.

1. With effect from the date set out in the second paragraph of Article 15, the national authorities shall refuse, to grant EC type-approval or national type-approval in respect of new types of vehicles on grounds relating to hydrogen propulsion or, to grant EC component type-approval or national type-approval in respect of new types of hydrogen components or systems, which do not comply with the requirements set out in this Regulation.

It is sensible to limit the obligation to type-approve components only to those using compressed (gaseous) hydrogen at a pressure higher than 3.0 MPa because this would avoid misunderstandings with the approval of parts exposed to lower pressure, approval of which would unnecessarily complicate the approval process (and which belong under point (a), which concerns parts for liquid hydrogen).

1. With effect from the date set out in the second paragraph of Article 15, the national authorities shall refuse to grant EC type-approval or national type-approval in respect of new types of vehicles on grounds relating to hydrogen propulsion, or to grant EC component type-approval or national type-approval in respect of new types of hydrogen components or systems, which do not comply with the requirements set out in this Regulation and its implementing measures.
