scope:

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.

When this standard is used to specify general requirements for MMAs to be used on launch vehicles, injection stages, reentry vehicles, or other vehicles, the term "space vehicle" is to be interpreted as the applicable vehicle.
