that may occur after engine shut-off and any necessary condition that must exist for monitoring to occur at the next start up.
 The test is considered complete as soon as the OBD system has responded in a manner that meets the requirements of this annex.
7.2. Applicable tests
 In the context of this annex:
(a) The emission test-cycle is the test-cycle used for the measurement of the regulated emissions when qualifying a deteriorated component or system;
(b) The OBD test-cycle is the test-cycle used to demonstrate the capacity of the OBD monitors to detect malfunctions.
7.2.1. Emission test cycle
 The test-cycle considered in this annex for measuring emissions is the WHTC test-cycle as described in Annex 4.
7.2.2. OBD test cycle
 The OBD test-cycle considered in this annex is the hot part of the WHTC cycle as described in Annex 4.
 On request of the manufacturer and after approval of the Type Approval Authority , an alternative OBD test-cycle can be used (e.g. the cold part of the WHTC cycle) for a specific monitor. The request shall contain documentation (technical considerations, simulation, test results, etc.) showing that:
(a) The requested test-cycle appropriate to demonstrate monitoring occurs under real world driving conditions; and
(b) The hot part of the WHTC cycle appears as less appropriate for the considered monitoring (e.g. fluid consumption monitoring).
7.2.3. Test operating conditions
 The conditions (i.e. temperature, altitude, fuel quality etc.) for conducting the tests referred to in paragraphs 7.2.1. and 7.2.2. shall be those required for operating the WHTC test cycle as described in Annex 4.
 In the case of an emission test aimed at justifying the classification of a specific malfunction into Class B1, the test operating conditions may, per decision of the manufacturer, deviate from the ones in the paragraphs above according to paragraph 6.2.2.
7.3. Demonstration process for performance monitoring
The manufacturer may use the demonstration requirements as set out in Appendix 7 to this annex in case of performance monitoring.
Type Approval authorities may approve a manufacturer's use of a type of performance monitoring technique other than the one referred to in Appendix 7 to this annex. The chosen type of monitoring shall be demonstrated by the manufacturer by a robust technical case based upon the design characteristics, or by presentation of test results, or by reference to previous approvals, or by some other acceptable method, to be at least as robust, timely and efficient as the ones mentioned in Appendix 7 to this annex.
7.4. Test reports
 The test report shall contain, at a minimum, the information set out in Appendix 4.
8. Documentation requirements
8.1. Documentation for purpose of approval
 The manufacturer shall provide a documentation package that includes a
