A.1.5.1.1.
Alternatively, if the manufacturer chooses, and subject to the agreement of the Type Approval Authority, the demonstration of vehicle speed limitation may be performed on a complete vehicle in accordance with the requirements of paragraph A.1.5.4., either by mounting the vehicle on a suitable test bed or by running it on a test track under controlled conditions.
A.1.5.2.
When the manufacturer applies for an approval of an engine or engine family as a separate technical unit, the manufacturer shall provide the Type Approval Authority with evidence that the installation documentation package complies with the provisions of paragraph 2.2.4. of this annex concerning the measures to ensure that the vehicle, when used on the road or elsewhere as appropriate, will comply with the requirements of this annex regarding severe inducement.
A.1.5.3.
If the Type Approval Authority is not satisfied with the evidence of proper operation of the severe inducement system that is provided by the manufacturer, the Type Approval Authority may request a demonstration on a single representative vehicle in order to confirm proper operation of the system.
The vehicle demonstration shall be performed in accordance with the requirements of paragraph A.1.5.4.
A.1.5.4.
Additional demonstration for confirming the effect of activation of the severe inducement system on a vehicle
A.1.5.4.1.
This demonstration shall be performed at the request of the Type Approval Authority when it is not satisfied with the evidence of proper operation of the severe inducement system provided by the manufacturer.
This demonstration shall be performed at the earliest opportunity in agreement with the Type Approval Authority.
A.1.5.4.2.
One of the failures defined in paragraphs 6. to 9. of this annex shall be selected by the manufacturer, and shall be introduced or simulated on the engine system, as the manufacturer and the Type Approval Authority agree.
A.1.5.4.3.
The inducement system shall be brought by the manufacturer to a state where the low-level inducement system has been activated and the severe inducement system has not yet been activated.
A.1.5.4.4.
The vehicle shall be operated until the counter associated with the selected failure has reached the relevant number of operating hours indicated in Table 2 of Appendix 2 or, as appropriate, until either the reagent tank is empty or, has reached the level below 2.5 per cent of nominal full capacity of the tank at which the manufacturer has chosen to activate the severe inducement system.
A.1.5.4.5.
If the manufacturer has opted for the "disable after restart" approach referred to in paragraph 5.4.1. of this annex, the vehicle shall be operated until the end of the current operating sequence, which must include a demonstration that the vehicle is capable of exceeding 20 km/h.
After restart, the vehicle speed shall be limited to no more than 20 km/h.
A.1.5.4.6.
If the manufacturer has opted for the "disable after fuelling" approach referred to in paragraph 5.4.2. of this annex, the vehicle shall be operated for a short distance, chosen by the manufacturer, after it has been brought to a state where there is sufficient spare capacity in the tank to permit it to be refuelled with the amount of fuel defined in paragraph 5.4.2. of this annex.
The vehicle operation before refuelling shall include a demonstration that the vehicle is capable of exceeding 20 km/h.
After re-fuelling the vehicle with the amount of fuel defined in paragraph 5.4.2. of this annex, the vehicle speed shall be limited to no more than 20 km/h.
A.1.5.4.7.
If the manufacturer has opted for the "disable after parking" approach referred to in paragraph 5.4.3. of this annex, the vehicle shall be stopped after having been run for a short distance, chosen by the manufacturer, which is sufficient to demonstrate that the vehicle is capable of exceeding a speed of 20 km/h.
After the vehicle has been stationary for more than one hour, the vehicle speed shall be limited to no more than 20 km/h.
