Human-Rating Certification

Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. The cited article notes that there is no one particular standard for human-rating a spacecraft or launch vehicle, and that the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated. In the atlas it names the class of launch vehicles built to carry crewed spacecraft, for which the certification is the defining requirement. Launch vehicles of this class are grouped under this concept.
