PD-ED-1215.3, CRITICAL DESIGN REVIEW FOR UNMANNED MISSIONS
PREFERRED RELIABILITY PRACTICES PD-ED-1215.3, CRITICAL DESIGN REVIEW FOR UNMANNED MISSIONS. Conduct a formal Critical Design Review (CDR) of hardware, software, and firmware at the subsystem and system levels. Schedule the review prior to the start of subsystem fabrication and assembly to assure that the design solutions satisfy the performance requirements established in the development specifications. Establish this review as a standard reliability engineering practice for flight hardware.

PD-ED-1252, NASA PREFERRED RELIABILITY PRACTICE MATERIAL SELECTION PRACTICES
PD-ED-1252, NASA PREFERRED RELIABILITY PRACTICE MATERIAL SELECTION PRACTICES. Aerospace systems designers must ensure that the most reliable material is used to meet the design requirements for aerospace systems. Test results regarding corrosion resistance, susceptibility to stress corrosion cracking, flammability, toxicity, thermal vacuum stability, and compatibility with rocket engine fuels, oxidizers, and hydraulic fluids; as well as extensive chemical and physical properties data; are included in the Materials and Processes Technical Information System (MAPTIS). This information is used to assist the aerospace designer in identifying the most reliable material candidates for space systems.
