7.1.The vehicle shall include a means of determining the presence of an incorrect reagent on board a vehicle.U.K.
7.1.1.The manufacturer shall specify a minimum acceptable reagent concentration CDmin, which results in tailpipe emissions not exceeding the limit values specified in Annex I to Regulation (EC) No 595/2009.U.K.
7.1.1.1.During the phase-in period specified in Article 4(7) and upon request of the manufacturer for the purpose of Section 7.1.1 the reference to the NOx emission limit specified in Annex I to Regulation (EC) No 595/2009 shall be replaced by the value of 900 mg/kWh.U.K.
7.1.1.2.The correct value of CDmin shall be demonstrated during type-approval by the procedure defined in Appendix 6 and recorded in the extended documentation package as specified in Article 3 and Section 8 of Annex I.U.K.
7.1.2.Any reagent concentration lower than CDmin shall be detected and be regarded, for the purpose of Section 7.1, as being incorrect reagent.U.K.
7.1.3.A specific counter (the reagent quality counter) shall be attributed to the reagent quality. The reagent quality counter shall count the number of engine operating hours with an incorrect reagent.U.K.
7.1.4.Details of the reagent quality counter activation and deactivation criteria and mechanisms are described in Appendix 2.U.K.
7.1.5.The reagent quality counter information shall be made available in a standardised manner in accordance with the provisions of Appendix 5.U.K.
