本文件详细规定了在地球轨道上运载火箭轨道级的设计和运行的空间碎片缓减要求和建议。 本文件中定义的要求适用于: -避免释放空间碎片； -在运载火箭任务结束后处置其轨道级，以避免在轨道上解体； -在运载火箭轨道级任务结束后处置，以尽量减少对保护区的干扰； -安全地重新进入运载火箭轨道阶段。

This document defines detailed space debris mitigation requirements and recommendations for the design and operation of launch vehicle orbital stages in Earth orbit. The requirements defined in this document are applicable for: — avoiding the release of space debris; — disposing of a launch vehicle orbital stage after the end of its mission so as to avoid a break-up in orbit; — disposing of a launch vehicle orbital stage after the end of its mission so as to minimize interference with the protected regions; — safely re-entering a launch vehicle orbital stage.
