本标准规定了用于航天器和运载火箭的移动机械组件（MMA）的设计、制造、质量控制、测试和储存的一般要求。本标准适用于控制空间或运载火箭机械部分相对于另一部分移动的机械或机电设备。这些要求适用于整个MMA以及作为这些机械组件组成部分的机械部件和仪器。与之前（2005年）版本相比，本修订版中最重要的更新包括重新格式化和编写的测试部分、计算力/扭矩裕度的新方法，以及取消“应，如果可行”要求的加权水平。

This standard specifies general requirements for the design, manufacture, quality control, testing, and storage of moving mechanical assemblies (MMAs) to be used on space and launch vehicles. This standard is applicable to the mechanical or electromechanical devices that control the movement of a mechanical part of a space or launch vehicle relative to another part. The requirements apply to the overall MMA as well as to the mechanical components and instrumentation that are an integral part of these mechanical assemblies. The most significant updates in this revision, relative to the previous (2005) version, include a reformatted andrewritten testing section, a new approach to calculating force/torque margin, and the elimination of the "shall, where practical" weighting level of requirements.
