This Standard sets out requirements and guidelines for the long term type testing, glazing, periodic manufacturing testing and other associated aspects to do with insulating glass units intended for use in the applications listed in Clause 1.2.NOTES: 1 Achieving satisfactory test results to this Standard does not imply a fit for purpose status to any specific application, and any such determination should be in accordance with the criteria specified in AS 1288 or any relevant statutory requirement, or both.2 Thermal, solar, light transmission and acoustic properties are excluded from this Standard. These and other design criteria including sealant type and sealant dimensional properties are considered to have been catered for as part of the architectural or engineering functions, or both.3 Manufacturing tests covered in this Standard subject samples only to the ambient temperatures existing at the time of manufacture, whilst testing conducted in accordance with this Standard subject units to a defined laboratory controlled temperature range. Consideration should be given to environmental extremes during the design phase which should allow for thermal build up during operating extremes. In particular, consideration should be given to the actual operating temperature of the insulating glass unit when determining sealant types.4 It is not the intention of this Standard to preclude new or existing products, or technologies where equal or superior performance can be demonstrated to that specified in this Standard. This applies equally to component types, test, installation and glazing methods.5 Testing for compliance with this Standard may involve the use of materials, equipment and methods that could be deemed hazardous. This Standard does not purport to address all the relevant safety aspects inherent to the test procedures and test personnel should consult the appropriate authorities in order to ascertain adequate safety procedures or compliance with relevant statutory requirements, or both.
