It's more than NASA, it's an international standard for the space community - see page 3-2 at:
http://public.ccsds.org/publications/archive/301x0b4.pdf

The same document is also ISO standard ISO 11104:2011:
http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=59415

The only difference between the two is that you can download the CCSDS standard for free, but the ISO cover-sheeted version costs you 134 Swiss Francs.
