1.4.2010 Official Journal of the European Union L 86/29 DIRECTIVES COMMISSION DIRECTIVE 2010/26/EU of 31 March 2010 amending Directive 97/68/EC of the European Parliament and of the Council on the approximation of the laws of the Member States relating to measures against the emission of gaseous and particulate pollutants from internal combustion engines to be installed in non-road mobile machinery (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 97/68/EC of 16 December 1997 of the European Parliament and of the Council on the approxi- mation of the laws of the Member States relating to measures against the emission of gaseous and particulate pollutants from internal combustion engines to be installed in non-road mobile machinery (1), and in particular Articles 14 and 14a thereof, Whereas: Article 14a of Directive 97/68[EC sets out the criteria and the procedure for extending the period referred to in Article 9a(7) of that Directive. Studies carried out in accordance with Article 14a of Directive 97/68/EC show that there are substantial technical difficulties to comply with stage II requirements for professional use, multi- positional, hand-held mobile machinery in which engines of classes SH:2 and SH:3 are installed. It is therefore necessary to extend the period referred to in Article 9a(7) until 31 July 2013. Since the amendment of Directive 97/68/EC in 2004, technical progress has been made in the design of diesel engines with a view to make them compliant with the exhaust emission limits for stages IIIB and IV. Electronically controlled engines, largely replacing me- chanically controlled fuel injection and control systems, have been developed. Therefore, the current general type- approval requirements in Annex I to Directive 97/68/EC should be adapted accordingly and general type-approval requirements for stages IIIB and IV should be introduced. (") OJ L 59, 27.2.1998, p. 1. (3) Annex II to Directive 97/68EC specifies the technical details of the information documents that need to be submitted by the manufacturer to the type-approval authority with the application for engine type-approval. The details specified regarding the additional anti- pollution devices are generic and should be adapted to the specific after-treatment systems that need to be used to ensure that engines comply with exhaust emission limit stages IIB and IV. More detailed information on the after-treatment devices installed on the engines should be submitted to enable type-approval authorities to assess the engine’s capability to comply with stages 1B and 1V. Annex III to Directive 97/68/EC sets out the method testing the engines and determining their level of emissions of gaseous and particulate pollutants. The type-approval testing procedure of engines to demon- strate compliance with the exhaust emission limits of stage IIIB and IV should ensure that the simultaneous compliance with the gaseous (carbon monoxide, hydro- carbons, oxides of nitrogen) and the particulate emission limits is demonstrated. The non-road steady cycle (NRSC) and non-road transient cycle (NRTC) should be adapted accordingly. Point 1.3.2 of Annex III to Directive 97/68/EC foresees the modification of the symbols (section 2.18 of Annex I), the test sequence (Annex IIT) and calculation equations (Appendix III to Annex IIl), prior to the introduction of the cold/hot composite test sequence. The type approval procedure to demonstrate compliance with the exhaust emission limits of stage IlIB and IV requires the intro- duction of a detailed description of the cold start cycle. Section 3.7.1 of Annex III to Directive 97/68/EC sets out the test cycle for the different equipment specifications. The test cycle under point 3.7.1.1 (specification A) needs to be adapted to clarify which engine speed needs to be used in the type approval calculation method. It is also necessary to adapt the reference to the updated version of the international testing standard ISO 8178-4:2007.
