Division 1 Definitions

For the purposes of this Annex, the following definitions apply:

1. 1.1.

   ‘Ageing cycle’ means the non-road mobile machinery or engine operation (speed, load, power) to be executed during the service accumulation period.

2. 1.2.

   ‘Critical emission-related components’ means the exhaust after- treatment system, the electronic engine control unit and its associated sensors and actuators, and the exhaust gas recirculation (EGR) including all related filters, coolers, control valves and tubing.

3. 1.3.

   ‘Critical emission-related maintenance’ means the maintenance to be performed on critical emission-related components of the engine.

4. 1.4.

   ‘Emission-related maintenance’ means the maintenance which substantially affects emissions or which is likely to affect emissions performance of the non-road mobile machinery or the engine during normal in-use operation.

5. 1.5.

   ‘Engine-after-treatment system family’ means a manufacturer's grouping of engines that comply with the definition of engine family, but which are further grouped into a family of engine families utilising a similar exhaust after-treatment system.

6. 1.6.

   ‘Non-emission-related maintenance’ means maintenance which does not substantially affect emissions and which does not have a lasting effect on the emissions performance deterioration of the non-road mobile machinery or the engine during normal in-use operation once the maintenance is performed.

7. 1.7.

   ‘Service accumulation schedule’ means the ageing cycle and the service accumulation period for determining the deterioration factors for the engine-after-treatment system family.
