This International Standard defines requirements and a procedure for assessing the survivability of  an unmanned spacecraft against  space debris and meteoroid impacts to ensure the survival of critical components required to perform post-mission disposal. This standard also describes two impact risk analysis procedures that may be used to satisfy the requirements. The procedures are consistent with those defined in References [1] and [2].

This International Standard is part of a set of standards that collectively aim to reduce the growth of space debris by ensuring that spacecraft and launch vehicle orbital stages are designed, operated, and disposed of in a manner that prevents them from generating debris throughout their orbital lifetime. All of the primary debris mitigation requirements are contained in a top-level standard ^[3]. The remaining standards, of which this is one, provide methods and processes to enable compliance with the primary requirements.

Although this International Standard can be applied during the design of a launch vehicle orbital stage, it is intended for use only during the design of an unmanned spacecraft.

This International Standard is a reference for quantitative measures of lunar simulants.  The quantitative measures of lunar simulants are based on the quantitative measures of lunar samples collected at multiple lunar landing sites of the Apollo and Lunakhod missions.
