The revised NZS 4223.3:2016 Glazing In Buildings — Part 3: Human Impact Safety Requirements is due for publication in late February/March this year.

Auckland Council has recently issued guidance to their building control staff for the assessment of structural glass balustrades until this standard is published and cited by the Building Code.

To ensure that due allowance is made for the consequences of failure of glass, it is understood that Auckland Council would be prepared to accept either one of the three glass and hardware options:

1. Glass: Viridian SentryGlas Toughened Laminated Safety Glass; Hardware: No additional hardware needed
2. Glass: Toughened laminated Viridian safety glass; Hardware:  Interlinking rail or top brackets connected to each glass pane and the building
3. Glass: Toughened Viridian safety glass; Hardware: interlinking rail connected to each glass pane and the building
