Before the dates specified in Article 4(8) of this Regulation and in the case of a wall-flow diesel particulate filter (DPF), the manufacturer may choose to apply the performance monitoring requirements set out in Appendix 8 of Annex 9B to UNECE Regulation No 49 instead of the requirements set out in paragraph 2.3.2.1, if he can demonstrate with technical documentation that in case of deterioration there is a positive correlation between the loss of filtration efficiency a ...[+++]nd the loss of pressure drop (delta pressure) across the DPF under the operating conditions of the engine specified in the tests described in Appendix 8 of Annex 9B to UNECE Regulation No 49”. ’.

(2) The difference of the burden is explained by the different situations prevailing in Member States as regards the geography of the external border, the number of authorised and operative border crossing points, the level of migratory pressure, both legal and illegal, the risks and threats encountered and finally the workload of the national services regarding the examination of visas applications and the issuing of visas.

(7) In order to achieve EU air quality objectives and to ensure a continuous effort to reduce vehicle emissions, the power to adopt delegated acts in accordance with Article 290 of the Treaty on the Functioning of the European Union (TFUE) should be delegated to the Commission in respect of the detailed rules on the application of Regulation (EC) No 715/2007 to vehicles of categories M1, M2, N1 and N2 with a reference mass exceeding 2 610 kg but with a maximum technically permissible laden mass not exceeding 7 500 kg, the specific procedures, tests and requirements for type approval, the requirements for the implementation of the prohibition on the use of defeat devices that reduce the effectiveness of emission control systems, the measures ...[+++] necessary for the implementation of the obligation of a manufacturer to provide unrestricted and standardised access to vehicle repair and maintenance information, the replacement of the information on the mass of CO2 emissions in the certificate of conformity with information on total mass of CO2 emissions equivalents, the increase or removal of the limit value of total hydrocarbons emissions for positive ignition vehicles, the amendment of Regulation (EC) No 715/2007 for the purposes of recalibrating the particulate mass based limit values and introducing particle number based limit values that would correlate broadly with the petrol and diesel mass limit values, the adoption of a revised measurement procedure for particulates and a particle number limit value, a limit value for emissions of NO2 and limits for tailpipe emissions at cold temperatures for vehicles approved as complying with the Euro 6 emission limits.
