Space engineering - Cleanliness requirements for spacecraft propulsion hardware

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 the most commonly used propulsion systems and their related storable propellant combinations: Hydrazine (N2H4), Mono Methyl Hydrazine (CH3N2H3), MON (Mixed Oxides of Nitrogen), Nitrogen (N2), Helium (He), Propane (C3H8), Butane (C4H10) and Xenon (Xe).
This standard is the basis for the European spacecraft and spacecraft propulsion industry to define, achieve and verify the required cleanliness levels in spacecraft propulsion systems.
This standard is particularly applicable to spacecraft propulsion as used for satellites and (manned) spacecraft and any of such projects including its ground support equipment.
External cleanliness requirements, e.g. outside of tanks, piping and aspects such as fungus and outgassing are covered by ECSS-Q-ST-70-01.
This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

Vesoljska tehnika - Zahteve za čistočo pogonske tehnike vesoljskih plovil

Standard ECSS-E-ST-35-06 sodi na pogonsko področje strojništva in zajema zahteve za čistočo pogonskih sestavnih delov, podsistemov in sistemov Standard - določa zahteve za projekt, ki omogočajo čiščenje pogonskih sestavnih delov podsistemov in sistemov in ki se izognejo nastajanju ali neželenemu nabiranju onesnaženja, - opredeljuje zahteve za čistočo (npr. kateri delec/nečistoča/raven vlažnosti je še dopusten), - določa zahteve glede čiščenja v skladu z zahtevami ravni čistoče in zahtevami za verifikacijo, - opredeljuje pristop za čistočo, zahteve za čiščenje (npr. kaj je treba storiti, da se zagotovi, da dopustna raven ni presežena, zahteve za združljivost), - opredeljuje, specificira in določa zahteve v zvezi s pogoji, pod katerimi poteka preverjanje čiščenja ali čistoče (npr. združljivost, preverjanje po okoljskem preskusu). Ta standard velja za večino najbolj pogosto uporabljenih pogonskih sistemov in njihovih povezanih, shranjenih kombinacij goriv: hidrazin (N2H4), monometil hidrazin (CH3N2H3), MON (mešani dušikovi oksidi), dušik (N2), helij (He), propan (C3H8), butan (C4H10) in ksenon (Xe). Ta standard je temelj za industrijo evropskih vesoljskih plovil in pogonsko industrijo za vesoljska plovila za določitev, doseganje in preverjanje zahtevanih ravni čistoče v pogonskem sistemu vesoljskega plovila. Ta standard še zlasti velja za pogon vesoljskih plovil, kot se uporablja za satelite in vesoljska plovila (s posadko) in katerega koli od teh projektov, vključno s podporno opremo na tleh. Zahteve za zunanjo čistočo, npr. izven rezervoarjev in cevi, in vidiki, kot so glive in razplinjevanje, so zajete v standardu ECSS-Q-ST-70-01. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
