However, where a gearbox is incorporated into the engine, the power shall be measured at the gearbox output flange.

No deduction shall be made in respect of auxiliary machines driven by the engine.

The unit in which engine power is expressed shall be the kilowatt (kW).

3.   The delegation of power referred to in Article 5(3) may be revoked at any time by the European Parliament or by the Council. A decision to revoke shall put an end to the delegation of the power specified in that decision.

That period shall be extended by two months at the initiative of the European Parliament or of the Council.
