EN 16603-35-06 (equivalent of ECSS-E-ST-35-06) belongs to the Propulsion field of the mechanical discipline, and concerns itself with the cleanliness of propulsion components, sub-systems and systems The standard - defines design requirements which allow for cleaning of propulsion components sub-systems and systems and which avoid generation or unwanted collection of contamination, - identifies cleanliness requirements (e.g. which particle / impurity / wetness level can be tolerated), - defines requirements on cleaning to comply with the cleanliness level requirements, and the requirements on verification, - identifies the cleanliness approach, cleaning requirements, (e.g. what needs to be done to ensure the tolerable level is not exceeded, compatibility requirements), - identifies, specifies and defines the requirements regarding conditions under which cleaning or cleanliness verification takes place (e.g. compatibility, check after environmental test). The standard is applicable to

This standard addresses the requirements for performing verification by testing of space segment elements and space segment equipment on ground prior to launch. The document is applicable for tests performed on qualification models, flight models (tested at acceptance level) and protoflight models. The standard provides: • Requirements for test programme and test management, • Requirements for retesting, • Requirements for redundancy testing, • Requirements for environmental tests, • General requirements for functional and performance tests, NOTE Specific requirements for functional and performance tests are not part of this standard since they are defined in the specific project documentation. • Requirements for qualification, acceptance, and protoflight testing including qualification, acceptance, and protofight models’ test margins and duration, • Requirements for test factors, test condition, test tolerances, and test accuracies, • General requirements for development tests pertine
