(Main)Space product assurance - Ultracleaning of flight hardware
Space product assurance - Ultracleaning of flight hardware
This ECSS Standard describes the procedures to be used to clean to a level of cleanliness beyond the scope of the ECSS-Q-ST-70-01, and to control the cleanliness level of flight hardware prior to and following a posteriori to the application of the ultracleaning process. The intended objective of the ultracleaning process is to remove all surface contamination (particulates, biologic material cell debris and chemical molecular contamination) on flight hardware, with no specific limit in geometric dimension or contamination levels. This includes removal of biological material for avoidance of false positive results during investigation of extra-terrestrial samples or environments.
Raumfahrtproduktsicherung - Ultra-Reinigung von Flug-Hardware
Assurance produit des projets spatiaux - Ultranettoyage des matériels de vol
Zagotavljanje kakovosti proizvodov v vesoljski tehniki - Ultra čiščenje letalske strojne opreme
Ta standard ECSS opisuje postopke, ki se uporabljajo za čiščenje do stopnje čistosti, ki presega področje uporabe standarda ECSS-Q-ST-70-01, in za nadzor stopnje čistosti letalske strojne opreme pred izvedbo postopka ultra čiščenja in po njem. Predviden cilj postopka ultra čiščenja je odstranitev vse površinske kontaminacije (delcev, celičnih ostankov bioloških snovi in kontaminacije s kemijskimi molekulami) na letalski strojni opremi, brez določenih mejnih vrednosti pri geometrijskih dimenzijah ali stopnjah kontaminacije. To vključuje odstranitev bioloških snovi, da se preprečijo lažni pozitivni rezultati pri preiskavi zunajzemeljskih vzorcev ali okolij.
