scope:

This 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. Project-specific 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 presense or operation of the item and its mission (e.g. contamination, secondary radiations and spacecrafts charging). The space environment also contains elements which are induced by the execution of other space activities (e.g. debris and contamination).
