         Annex 10 Requirements to limit Off-Cycle Emissions (OCE) and in-use emissions
1.  Applicability
                This annex sets out the performance requirements and prohibition of defeat strategies for engines and vehicles type-approved according to this Regulation so as to achieve effective control of emissions under a broad range of engine and ambient operating conditions encountered during normal in-use vehicle operation. This annex also sets out the test procedures for testing off-cycle emissions during type approval and in actual use of the vehicle.
This annex is based on the world-wide harmonized OCE, global technical regulation (gtr) No. 10.
              2. Reserved[47]
3.  Definitions
3.1. "Engine starting" means the process from the initiation of engine cranking until the engine reaches a speed 150 min-1 below the normal, warmed up idle speed (as determined in the drive position for vehicles equipped with an automatic transmission).
3.2. "Engine warm-up" means sufficient vehicle operation such that the coolant temperature reaches a minimum temperature of at least 70 °C.
3.3. "Rated speed" means the maximum full load speed allowed by the governor as specified by the manufacturer in his sales and service literature, or, if such a governor is not present, the speed at which the maximum power is obtained from the engine, as specified by the manufacturer in his sales and service literature.
3.4. "Regulated emissions" means "gaseous pollutants" and "particulate matter" (PM) as defined in paragraph 2. of this Regulation.
4.  General requirements
 Any engine system and any element of design liable to affect the emission of regulated pollutants shall be designed, constructed, assembled and installed so as to enable the engine and vehicle to comply with the provisions of this annex.
4.1. Prohibition of defeat strategies
 Engine systems and vehicles shall not be equipped with a defeat
