documentation package that gives access to any element of design and emission control strategy (ECS), and torque limiter of the engine system and the means by which it controls its output variables, whether that control is direct or indirect. The documentation shall be made available in two parts:

            (a)     the formal documentation package, which shall be supplied to the technical service at the time of submission of the type-approval application, shall include a full description of the ECS and, if applicable, the torque limiter. This documentation may be brief, provided that it exhibits evidence that all outputs permitted by a matrix obtained from the range of control of the individual unit inputs have been identified. This information shall be attached to the documentation required in section 3 of this Annex;

            (b)     additional material that shows the parameters that are modified by any auxiliary emission control strategy (AECS) and the bound- ary conditions under which the AECS operates. The additional material shall include a description of the fuel system control logic, timing strategies and switch points during all modes of operation. It shall also include a description of the torque limiter described in section 6.5.5 of this Annex.

         The additional material shall also contain a justification for the use of any AECS and include additional material and test data to dem- onstrate the effect on exhaust emissions of any AECS installed to the engine or on the vehicle. The justification for the use of an AECS may be based on test data and/or sound engineering analysis.

         This additional material shall remain strictly confidential, and be made available to the type-approval authority on request. The type- approval authority will keep this material confidential.

         6.1.8.            Specifically for the type-approval of engines according to row A of the tables in section 6.2.1 (engines not normally tested on ETC)

         6.1.8.1.        To verify whether any strategy or measure should be considered a defeat strategy according to the definitions given in section 2, the type-approval authority and/or the technical service may additionally request a NOx screening test using the ETC which may be car- ried out in combination with either the type-approval test or the procedures for checking the conformity of production.

         6.1.8.2.        In verifying whether any strategy or measure should be considered a defeat strategy according to the definitions given in section 2, an additional margin of 10 %, related to the appropriate NOx limit value, shall be accepted.

         6.1.9.            The transitional provisions for extension of type-approval are given in section 6.1.5 of Annex I to Directive 2001/27/EC.

         Until the 8 November 2006, the existing approval certificate number will remain valid. In case of extension, only the sequential num- ber to denote the extension base approval
