A.1.4.6.1. This demonstration shall start from a condition where the low-level inducement system has been previously activated, and may be performed as a continuation of the tests undertaken to demonstrate the low-level inducement system.
A.1.4.6.2. When the system is checked for its reaction in the case of lack of reagent in the tank, the engine system shall be run until the reagent tank is empty (that is, until the dosing system cannot draw further reagent from the tank), or has reached the level below 2.5 per cent of nominal full capacity of the tank at which the manufacturer has declared that the severe inducement system will be activated.
A.1.4.6.2.1. The manufacturer may, with the agreement of the Type Approval Authority, simulate continuous running by extracting reagent from the tank, either whilst the engine is running or whilst it is stopped.
A.1.4.6.3. When the system is checked for its reaction in the case of a failure that is not a lack of reagent in the tank, the engine system shall then be run for the relevant number of operating hours indicated in Table 2 of Appendix 2 or, at the choice of the manufacturer, until the relevant counter has reached the value at which the severe inducement system is activated.
A.1.4.6.4. The demonstration of the severe inducement system shall be deemed to be accomplished if, at the end of each demonstration test performed in accordance with paragraphs A.1.4.6.2. and A.1.4.6.3. the manufacturer has demonstrated to the Type Approval Authority that the required vehicle speed limitation mechanism has been activated.
A.1.5. Demonstration of the vehicle speed limitation following activation of the severe inducement system
A.1.5.1. The demonstration of the vehicle speed limitation following activation of the severe inducement system shall be performed by the presentation to the Type Approval Authority of a technical case using evidence such as algorithms, functional analyses, and the result of previous tests.
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
