NASA-STD-5019A (W/ CHANGE-1), NASA TECHNICAL SPECIFICATION: FRACTURE CONTROL REQUIREMENTS FOR SPACEFLIGHT HARDWARE (26-FEB-2016)

NASA-STD-5019A (W/ CHANGE-1), NASA TECHNICAL SPECIFICATION: FRACTURE CONTROL REQUIREMENTS FOR SPACEFLIGHT HARDWARE (26-FEB-2016)., The purpose of this NASA Technical Standard is to establish the fracture control requirements for National Aeronautics and Space Administration (NASA) human-rated spaceflight hardware. In accordance with NASA Procedural Requirements (NPR) 8705.2B, Human-Rating Requirements for Space Systems, it is NASA’s policy to produce human-rated space systems that have failure tolerance for catastrophic events or that potentially catastrophic hazards are controlled through a defined process in which approved standards and margins are implemented that account for the absence of failure tolerance. This NASA Technical Standard supersedes the baseline release of NASA-STD-5019, Fracture Control Requirements for Spaceflight Hardware. Programs that are not human-rated may choose to impose these requirements on a mission or hardware to bolster the program or to serve as a stepping-stone for human rating. This NASA Technical Standard is published by the National Aeronautics and Space Administration (NASA) to provide uniform engineering and technical requirements for processes, procedures, practices, and methods that have been endorsed as standard for NASA programs and projects, including requirements for selection, application, and design criteria of an item. This NASA Technical Standard is approved for use by NASA Headquarters and NASA Centers and Facilities and may be cited in contract, program, and other Agency documents as a technical requirement. It may also apply to the Jet Propulsion Laboratory and other contractors only to the extent specified or referenced in applicable contracts. This NASA Technical Standard establishes the fracture control requirements for human-rated spaceflight, since NASA policy states that fracture control be imposed on all human-rated spaceflight hardware. It was developed by a NASA-wide Fracture Control Working Group to provide a common framework for fracture control practices on NASA programs.
