BS ISO 10784-3 pdf download Space systems — Early operations Part 3: Commissioning report
1 Scope A general definition of initialization is that it begins at separation of the spacecraft (SC) from the launcher. In some cases, a more exact definition will be that initialization begins in flight, upon planned change in mode or state of the SC from the launch configuration. Commissioning is completed when the SC, including its payload, is certified for initial mission operations. Prior to certification for mission operations, the SC is described as a test article in the three parts of ISO 10784. ISO 10784 does not include a requirement for contingency plans, but does include a statement of the need for contingency planning.
This part of ISO 10784 outlines general descriptive information for SC initialization and commissioning as might be appropriate for programme management, project engineering or programme test documentation. Since the SC is considered a test article at this phase of its operational life, ISO 17566 is used as a normative reference in constructing the commissioning report. It provides SC manufacturers, SC operators and other stakeholders with a common language and form to verify and document spacecraft initialization and commissioning prior to normal SC mission operations.

4 Introduction clause of the commissioning report
This clause shall provide general information about the technical content of the commissioning report of interest. It shall include a brief description of the initialization sequence events. The overall initialization objective shall be described, and the criteria for SC certification shall be stated.
4.2 Overall sequence of events This subclause shall summarize the overall sequence of tests conducted to demonstrate the acceptance status of the SC with respect to the launch environment and shall explain how the test in question fits into this sequence. The following types of test shall be considered, if applicable to the SC initialization programme: functional tests and operational tests.
