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 full description of the OBD system. The documentation package shall be made available in two parts:
(a) A first part, which may be brief, provided that it exhibits evidence concerning the relationships between monitors, sensors/actuators, and operating conditions (i.e. describes all enable conditions for monitors to run and disable conditions that cause monitors not to run). The documentation shall describe the functional operation of the OBD, including the malfunction ranking within the hierarchical classification. This material shall be retained by the Type Approval Authority. This information may be made available to interested parties upon request;
(b) A second part containing any data, including details of qualified deteriorated components or systems and associated test results, which are used as evidence to support the decision process referred to above, and a listing of all input and output signals that are available to the engine system and monitored by the OBD system. This second part shall also outline each monitoring strategy and the decision process.
 This second part shall remain strictly confidential. It may be kept by the Type Approval Authority or, at the discretion of the Type Approval Authority, may be retained by the manufacturer but shall be made open for inspection by the Type Approval Authority at the time of approval or at any time during the validity of the approval.
8.1.1. Documentation associated with each monitored component or system
 The documentation package included in the second part shall contain but shall not be limited to the following information for each monitored component or system:
(a) The malfunctions and associated DTC(s);
(b) The monitoring method used for malfunction detection;
(c) The parameters used and the conditions necessary for malfunction detection and when applicable the fault criteria limits (performance and component monitoring);
(d) The criteria for storing a DTC;
(e) The monitoring "time length" (i.e. the operation time/procedure necessary to complete the monitoring) and the monitoring "frequency" (e.g. continuous, once per trip, etc.).
8.1.2. Documentation associated with the malfunction classification
 The documentation package included in the second part shall contain but shall not be limited to the following information for malfunction classification:
 The malfunction classification of each DTC shall be documented. This classification may be different for different engine types (e.g. different engine ratings) within the same emission-OBD family.
 This information shall include the technical justification required in paragraph 4.2. of this annex for classification into Class A, Class B1 or Class B2.
8.1.3. Documentation associated with the emission-OBD family
 The documentation
