(Main)Space product assurance - Corrosion
Space product assurance - Corrosion
The purpose of the proposed Standard is to summarise the (general) corrosion protection requirements applicable to the materials, surface treatments, finishing and manufacturing processes used for space flight hardware.
It contains the minimum requirements necessary to guarantee and verify the suitability of materials, coatings systems and processes for corrosion control of space rated products.
The Standard classifies the corrosion environments and requires the issuing of a Corrosion Prevention and Control Plan based on the identified environmental classes. Testing and acceptance criteria are specified for each environmental class.
The scope of the document would include all flight parts and components used for space missions including Ground Support Equipment (GSE), where the materials and processes used in interfacing ground support equipment, test equipment, hardware processing equipment, hardware packaging and hardware shipment are to be controlled in order to prevent damage to or contamination of flight hardware.

Assurance produit des projets spatiaux - Corrosion
Le présent document spécifie les exigences minimales pour qualifier les matériaux et procédés sélectionnés afin d'obtenir une protection contre la corrosion. Des essais supplémentaires peuvent être réalisés pour satisfaire aux exigences relatives aux matériaux et procédés utilisés pour des applications de vol spécifiques.
La présente norme spécifie le comportement des métaux et alliages mais n'ôte pas la responsabilité concernant la dégradation des autres matériaux à considérer.
Le présent document ne couvre par les exigences relatives à la protection contre la fissuration par corrosion sous contrainte, traitées par une norme dédiée, l’ECSS-Q-ST-70-36.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d'un projet spatial, conformément à l'ECSS-S-ST-00.
Zagotavljanje varnih proizvodov v vesoljski tehniki - Korozija
Namen predlaganega standarda je povzeti (splošne) zahteve za zaščito pred korozijo, ki se uporabljajo za materiale, površinsko obdelavo, končno obdelavo in proizvodne procese, ki se uporabljajo za strojno opremo v vesoljskih poletih. Vsebuje minimalne zahteve, ki so potrebne za zagotovitev in preverjanje primernosti materialov, premaznih sistemov in procesov za nadzor korozije vesoljskih izdelkov. Standard razvršča korozijska okolja in zahteva izdajo načrta za preprečevanje in nadzor korozije, ki temelji na opredeljenih okoljskih razredih. Za vsak okoljski razred so določeni kriteriji preskušanja in sprejemljivosti. Področje uporabe dokumenta vključuje vse dele za letenje in komponente, ki se uporabljajo za vesoljske misije, vključno s podporno opremo na tleh (GSE), kjer se materiali in procesi, ki se uporabljajo pri povezovanju podporne opreme na tleh, preskusne opreme, opreme za obdelavo strojne opreme, embalaže strojne opreme in pošiljanja strojne opreme nadzorujejo, da se prepreči poškodovanje ali kontaminacija letalske strojne opreme.
