# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 7.7.1.2: Generation of NRSC test speeds for engines only tested with NRSC

Extent: E+W+S+N.I.

For engines that are not tested with a transient (NRTC or LSI-NRTC) test cycle, the rated speed specified in point 5.2.5.3 shall be used as the 100 % speed.
The rated speed shall be used to determine the intermediate speed in accordance with point 5.2.5.4. If the NRSC specifies additional speeds as a percentage they shall be calculated as a percentage of the rated speed.
The idle speed shall be determined in accordance with point 5.2.5.5.
With prior approval of the technical service, MTS may be used instead of rated speed for the generation of test speeds in this point.
