BAKGRUNN (fra kommisjonsforordningen)
(1) In the interests of public health, environmental protection and fair competition, it is important to ensure that vehicles in operation are properly maintained and tested, so that they can maintain their performance as guaranteed by type-approval, without excessive degradation, throughout their lifetime.
(2) The test methods required by Directive 2014/45/EU of the European Parliament and of the Council as regards exhaust emissions of motor vehicles, notably the opacity testing applicable to compression ignition engines, are not adapted to more recent vehicles that are equipped with particle filters. Laboratory tests indicate that even vehicles with defective or tampered diesel particulate filters (‘DPF’) can pass the opacity test, without the malfunctioning being noticed.
(3) In order to be able to detect those vehicles that have defective DPF, certain Member States have introduced or will soon introduce methods for particle number (‘PN’) measurement as part of their periodic technical inspection of vehicles equipped with compression ignition engines. While those methods are similar, they do differ in certain aspects. Instead of the introduction of various different measurement methods in the Union, a common set of minimum requirements for PN measurement should be introduced on the basis of guidelines.
(4) Existing methods developed by certain Member States, the findings of laboratory tests carried out by the Joint Research Centre of the Commission, as well as the results of the consultation of the Roadworthiness Expert Group have been duly taken into account when elaborating such guidelines.
(5) Since the applicability of such guidelines has not been tested for vehicles equipped with positive ignition engines, the scope of the guidelines should be limited to those equipped with compression ignition engines and having a solid particle number limit at their type-approval. This means light-duty diesel vehicles first registered as of 1 January 2013 (Euro 5b and newer) and heavy-duty diesel vehicles first registered as of 1 January 2014 (Euro VI and newer). As soon as the same level of confidence is reached regarding a PN measurement method applicable to vehicles equipped with positive ignition engines, corresponding guidelines should be developed.
(6) In order to be effective, the guidelines should include requirements related to the measuring equipment, metrological controls, the measurement procedure, metrological and technical requirements, as well as a pass/fail limit.
(7) This Recommendation is a first step towards harmonised PN measurement during roadworthiness testing within the Union,
