CCSDS Recommendations are routinely submitted to the International Organization for Standardization (ISO) for adoption as
international standards. In 1990, the CCSDS entered into a cooperative arrangement with Sub-Committee 13 under Technical Committee 20 of ISO.
Under this arrangement, CCSDS-developed Recommendations are advanced to ISO TC20/SC13 where they are progressed, via the normal ISO procedures of review
and voting, into ISO/CCSDS Standards. These documents retain the CCSDS format, but are appended with an ISO cover sheet and control number.
ISO TC20/SC13 normally meets every six months in conjunction with the CCSDS Management Council meetings.
