Did you know that JPL employees have a single point of access to technical standards, tools, and best practices? The NASA Technical Standards Program’s (NTSP) Standards System, sponsored by the Office of the NASA Chief Engineer, provides one-stop access to a wide range of standards, including those from NASA, NASA Centers, ISO (International Standards Organization) and other major standards organization. The URL for the site is [https://standards.nasa.gov]
NASA and Center Standards, Technical Memoradums (TM) and Technical Reports (TRs) can all be accessed from this site.
If the standard you are looking for is not displayed in one of the pages from this site, you can login then search for it. To login, you need your NASA LaunchPad ID. If that standard is NOT in the subscribed collection, there is a provision to request it right there (usually pretty quick, a few days).
NOTE that standards suppliers typically watermark and/or footer standards that users download, with the user’s name, date, etc. – the standards are NOT intended to be distributed further.
At JPL, the Office of the Chief Knowledge Officer is the contact for questions regarding NASA and JPL Standards.
P.S. If you are looking for IEEE Standards, they are also available through the JPL Library’s subscription to IEEE Explore.
