Scope

This document specifies the basic requirements for ground simulation tests of spacecraft components in space environmental effects, including the laboratory environment, test systems (including vacuum systems, test control systems, and test measurement systems), test specimens, and test safety, as well as the specific requirements for different ground simulation tests of space environmental effects (including vacuum cold welding tests, vacuum discharge tests, thermal tests, outgassing tests, micro-vibration tests, total ionizing dose effect tests, surface charge and discharge effect tests, atomic oxygen erosion effect tests, UV radiation effect tests, and strong magnetic field effect tests).
This document is applicable to ground simulation tests of spacecraft components during their in-orbit flight phase. It can also be used as a reference for space environmental effects ground simulation tests at the system and subsystem levels of spacecraft systems.
