A note about ISO DIS documents

This document is a Draft International Standard (DIS) published by ISO. Draft International Standards are circulated to all ISO member bodies comment and voting, usually with a five month period. Subject to approval by ISO members, it is then issued as a Final Draft International Standard (FDIS). If the approval criteria are not met, the text is returned to the originating Technical Committee for further study and a revised DIS will again be circulated for comment and voting. Users wishing to comment should contact Standards Australia, or their national standards body.
