Stage 4: Enquiry Stage
The DIS is circulated to all ISO member bodies by ISO CS for voting and comment within a period of five months.
It is approved for submission as a Final Draft International Standard (FDIS) if a 2/3 majority of the P-members of the TC are in favor and not more than 1/4 of the total number of votes cast are negative.
If the approval criteria are not met, the text is returned to the originating SC for further study and a revision and subsequent DIS voting
