Structural & Water Performance
The Australian Standard for windows AS2047 was called up into the Building Code of Australia on the 30th June 1999. As a result all window manufacturers must now label their windows with:
• their identification mark; and
• the product's window rating and water penetration resistance.
Manufacturers must also be capable of verifying a product's performance claim. The Australian standard provides manufacturers with several means of demonstrating compliance however the majority of the industry have chosen the 3rd party certification provided by the Australian Window Association.
The AWA's Performance Certification scheme requires manufacturers to:
-
Have their product's design tested in a NATA accredited testing laboratory and they must pass the requirements of AS2047.
- During these tests sample windows are subjected to:
- Simulations of high winds and driving rains
- Operating Force requirement
- Air infiltration pressure
- Ultimate proof testing
- Register these test results with the Association.
- Permit audits of their factories so that validation can
be made by NATA accredited auditors that the product manufactured is the
equal to that which has been design tested.
- Agree to CSIRO site inspections in an effort to conclude unresolved product liability claims.
- Provide a minimum 6 year product guarantee.
