This page explains what AS/NZS 4777.1 covers and where it sits against the other standards. It does not reproduce the standard, and it is not a substitute for it. For the requirements themselves, work from the current published edition, available from the Standards Australia store. Compliance is determined by a licensed professional working to the current edition.
