EN 14092:2002

Space engineering - Space environment

This European Standard applies to all product types which exist or operate in space and defines the natural environment for all space regimes. It also defines general models and rules for determining the local induced environment.
Project­specific or project­class­specific acceptance criteria, analysis methods or procedures are not defined.
The natural space environment of a given item is that set of environmental conditions defined by the external physical world for the given mission (e.g. atmosphere, meteoroids and energetic particle radiation). The induced space environment is that set of environmental conditions created or modified by the presence or operation of the item and its mission (e.g. contamination, secondary radiations and spacecraft charging). The space environment also contains elements which are induced by the execution of other space activities (e.g. debris and contamination).

Raumfahrttechnik (Engineering) - Raumfahrtumweltbedingungen

Diese Norm gilt für alle für den Betrieb im Weltraum vorliegenden und eingesetzten Produkttypen und legt die natürlichen Umgebungsbedingungen für alle Raumflugregime fest. Sie legt weiterhin allgemeine Modelle und Regeln zur Bestimmung der vor Ort künstlich erzeugten Umgebung fest.
Projektspezifische oder projektklassenspezifische Abnahmekriterien, Analysemethoden oder -verfahren werden nicht festgelegt.
Die natürliche Weltraumumgebung einer gegebenen Einheit ist der Satz Umgebungsbedingungen, die durch die externe körperliche Umwelt für eine gegebene Mission vorgegeben sind (z. B. Atmosphäre, Meteoroide und energiereiche Teilchenstrahlung). Die künstlich erzeugte Weltraumumgebung ist der Satz Umgebungsbedingungen, die durch das Vorhandensein oder den Betrieb der Einheit und ihrer Mission hervorgerufen oder modifiziert werden (z. B. Kontamination, Sekundärstrahlungen und Aufladung des Raumfahrzeugs). Weiterhin umfasst die Weltraumumgebung Elemente, die infolge der Durchführung anderer Aktivitäten im Weltraum künstlich erzeugt werden (z. B. Weltraummüll und Kontamination).

This European Standard was approved by CEN on 26 December 2001.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.
