With effect from 6 July 2008 and until 6 July 2010, the vehicle to be type-approved shall be subject to the test laid down in Annex 10 of UN/ECE Regulation No 51 for monitoring purposes only. The results of that test shall be added to the documents set out in Appendices 1 and 2 of Annex I to Directive 70/157/EEC as amended by this Directive, in conformity with Annex 9 of UN/ECE Regulation No 51. The Member State concerned shall send such information documents to the Commission. These obligations do not affect cases of extension of existing approvals according to this Directive. For the purpose of this monitoring procedure a vehicle is not considered to be a new type if the vehicle differs only in respect to paragraphs 2.2.1 and 2.2.2 of UN/ECE Regulation No 51.
