Commission Delegated Regulation (EU) 2018/987 of 27 April 2018 amending and correcting Delegated Regulation (EU) 2017/655 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to monitoring of gaseous pollutant emissions from in-service internal combustion engines 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 Regulation (EU) 2016/1628 of the European Parliament and of the Council of 14 September 2016 on requirements relating to gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery, amending Regulations (EU) No 1024/2012 and (EU) No 167/2013, and amending and repealing Directive 97/68/EC [^ntr1-L_2018182EN.01004001-E0001], and in particular Article 19(2) thereof,

Whereas:

• (1) Commission Delegated Regulation (EU) 2017/655 [^ntr2-L_2018182EN.01004001-E0002] lays down, inter alia, the procedures for the monitoring of gaseous pollutant emissions from in-service internal combustion engines installed in non-road mobile machinery.

• (2) Pursuant to Table III-1 of Annex III to Regulation (EU) 2016/1628, the mandatory dates of application for EU type-approval and placing on the market of engines of sub-category NRE-v-5 is one year later than for engines of sub-category NRE-v-6.

• (3) Therefore, to facilitate manufacturers of these NRE-v-5 engines of lower power ranges to comply with the limit dates for submitting test results to the approval authorities set out in Delegated Regulation (EU) 2017/655, the required duration of accumulated service of in-service internal combustion engines installed in non-road mobile machinery and tested in the framework of monitoring of gaseous pollutant emissions should be reduced for that sub-category of engines.

• (4) For the purpose of clarity, it should be stated in Appendix 5 of the Annex to Delegated Regulation (EU) 2017/655 that the reference work and reference CO2 mass used by the manufacturer in the procedures for the calculation of gaseous pollutant emissions for an engine type, or any engine type within the same engine family, are those specified in the addendum of the EU type-approval certificate of the engine type, or the engine family, in accordance with the template set out in Annex IV to Commission Implementing Regulation (EU) 2017/656 [^ntr3-L_2018182EN.01004001-E0003].

• (5) To avoid mistakes in the rounding of gaseous pollutant emissions calculations, it should be clarified that the applicable exhaust emissions limit values are set out in Article 18(2) of Regulation (EU) 2016/1628.

• (6) To ensure the internal consistency of the Delegated Regulation (EU) 2017/655 and to align it with Commission Delegated Regulation (EU) 2017/654 [^ntr4-L_2018182EN.01004001-E0004], certain measurement units should be revised.

• (7) Following the publication of Delegated Regulation (EU) 2017/655, errors of different types, including incorrect assignment of responsibilities and mistakes in certain equations, have been detected and need to be corrected.

• (8) Delegated Regulation (EU) 2017/655 should therefore be amended and corrected accordingly,
