Test cycles and weighting factors to be applied:
The following requirements of ISO standard 8178-4:2007 shall be used, taking into account the values set out in the table below.

[Notified] [Approved] bodies may accept tests carried out on the basis of other tests cycles as specified in a [harmonised] [designated] standard and as applicable for the engine duty cycle.
2.4.Application of the propulsion engine family and choice of parent propulsion engine
The engine manufacturer shall be responsible for defining those engines from his range which are to be included in an engine family.
A parent engine shall be selected from an engine family in such a way that its emissions characteristics are representative for all engines in that engine family. The engine incorporating those features that are expected to result in the highest specific emissions (expressed in g/kWh), when measured on the applicable test cycle, should normally be selected as the parent engine of the family.
2.5.Test fuels
The test fuel used for exhaust emission testing shall meet the following characteristics:
