In addition, the report shall evaluate the tests required for EU type-approval as set out in Articles 24 and 25, with a particular focus on the extent to which those tests correspond to real engine operation conditions, and it shall also evaluate the feasibility of introducing tests for particulate pollutant emissions as part of the in-service testing set out in Article 19.

5. An engine that is representative of the engine type or, where applicable, of the parent engine of the engine family, or an engine selected in accordance with the second subparagraph of paragraph 3, shall be tested on a dynamometer using the applicable non-road steady-state test cycle identified in Tables IV-1 to IV-10 of Annex IV. The manufacturer may choose whether to conduct that test using the discrete-mode or the ramped-modal test method.

‘steady-state test cycle’ means a test cycle in which engine speed and torque are held at a finite set of nominally constant values; steady-state tests are either discrete mode tests or ramped-modal tests.

6. Welcomes the efforts of the Commission to develop real driving emissions tests and calls for work in this regard to be accelerated and an ambitious flexibility factor to be agreed on so as to make possible the deployment of the aforementioned testing; recalls, however, that this flexibility will not be used to modify the substance of the existing regulation; calls for the quick revision of the homologation procedure in order to make it representative and to reduce unjustified flexibilities, such as testing at maximum temperatures or testing tyres at high pressure levels; calls for the swift phasing-in of the Worldwide Harmonised Li ...[+++]ght Vehicles Test Procedure (WLTP) developed under the aegis of the UN Economic Commission for Europe (UNECE);
