use under steady state and transient conditions are:

                —    an altitude not exceeding 1 000 metres (or equivalent atmospheric pressure of 90 kPa),

                —    an ambient temperature within the range 283 to 303 K (10 to 30 °C),

                —    engine coolant temperature within the range 343 to 368 K (70 to 95 °C).

6.1.3.                        Special requirements for electronic emission control systems

6.1.3.1.                    Documentation requirements

              The manufacturer shall provide a documentation package that gives access to the basic design of the 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 system. 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 Annex I, Section 3;

                (b)    additional material that shows the parameters that are modified by any auxiliary control device and the boundary conditions under which the device operates. The additional material shall include a description of the fuel system control logic, timing strategies and switch points during all modes of operation.

                The additional material shall also contain a justification for the use of any auxiliary control device      and include additional material and test data to demonstrate the effect on exhaust emissions of any auxiliary control device installed to the engine or on the vehicle.

                This additional material shall remain strictly confidential and be retained by the manufacturer, but be made open for inspection at the time of type-approval or at any time during the validity of the type- approval.

6.1.4.                        To verify whether any strategy or measure should be considered a defeat device or an irrational emission control strategy according to the definitions given in Sections 2.29 and 2.31, the type-approval authority and/or the technical service may additionally request a NOx screening test using the ETC which may be carried out in combination with either the type-approval test or the procedures for checking the conformity of production.

6.1.4.1.                    As an alternative to the requirements of Appendix 4 to Annex III the emissions of NOx during the ETC screening test may be sampled using the raw exhaust gas and the technical prescriptions of ISO DIS 16183, dated 15 October 2000, shall be followed.

6.1.4.2.                    In verifying whether any strategy or measure should be considered a defeat device or an irrational emission control strategy according to the definitions given in Sections 2.29 and 2.31,
