| NZ Safety Standards |
 |
| AMN will not compromise on Glazing standards. |
|
| Within the glazing market, the key standard to abide
by is NZS 4223 which deals
with “Glazing in Buildings”. |
|
| To follow is a quick summary of the different parts
which make up NZS 4223. To obtain any of these standards please visit
the New Zealand Standards website. |
|
 |
|
| NZS 4223.1&2:1985 Code of Practise |
| Parts 1 & 2 lay down the requirements and recommendations
for the selection of glass for buildings, paying particular attention
to loading, thermal control, and human impact safety as well as general
design principles. Part 1 covers design and installation considerations
for the general situation and deals with safety requirements. Part
2 relates specifically to sealed insulating glass units. |
|
| NZS 4223.3:1999 Human impact safety requirements |
| Part 3 looks at the minimum requirements for glazing
in buildings in locations where it could be subject to human impact,
with the intention of reducing the risk of personal injury. |
|
| NZS 4223.4:2000 Dead, wind and snow loading |
| Part 4 provides information on the determination of
minimum glass thicknesses for vertical and sloped glazing in New
Zealand governed by the limit state
loadings. It supersedes the design requirements given in Part 1 concerning
the selection of glazing for dead, wind and snow loading. |
|
| In addition a useful standard, which is referred to
regularly in Part 3, is: |
|
| AS/NZS 2208:1996 Safety glazing materials in buildings |
| This standard specifies the functional properties
of various safety glass, including toughened glass, laminated glass,
wired glass, organic-coated glass and plastic. |
