Spacecraft Surplus Prevention and Control Requirements

1 Scope

China's national requirements for preventing foreign object debris on spacecraft. It specifies the terms, definitions and abbreviations and the requirements. Foreign object debris is anything left where it should not be during manufacture, assembly or test - a swarf chip, a washer, a fragment of lock wire, a piece of tape, a hair. On the ground it is a housekeeping matter; in orbit it is a mechanism failure waiting for the moment of weightlessness, when whatever has been resting quietly in a corner floats free and lodges in a bearing, shorts a connector or lands on an optic. The consequences are wholly out of proportion to the object, and the failures are effectively undiagnosable from telemetry. Prevention is entirely procedural: control of what enters a clean area, accounting for tools and hardware, inspection at closure of every compartment, and design that avoids traps where debris can lodge unseen.

This standard specifies the general requirements for the prevention and control of spacecraft redundant objects, as well as the design, assembly, testing, testing, packaging, and transportation of spacecraft. The requirements for the prevention and control of redundant objects in the process of transmission and launch site work (hereinafter referred to as the development process). This standard applies to the prevention and control of redundant objects during the development of spacecraft such as satellites, spacecraft, space stations, and space probes. Stand-alone production The prevention and control of redundant materials in the product development process can be implemented by reference.
