Pre-release version (PRV)

A Pre-release version allows users to access the content of an upcoming publication up to two months prior to its official release. A PRV contains the final draft international standard (FDIS) of a publication. The FDIS is the last approval stage in the development process of a publication when only minor editorial changes are permitted. During the six week voting period, the FDIS is made available as a PRV. Those who purchase a PRV also receive the official publication at the time of its release.
