testing Research and Development plays a pivotal role in our product design
and provide a windows and door testing laboratory to conduct test required
for AS 2047:2014 Windows and external glazed doors in buildings
and NZS 4211:2008 Specification for performance of windows Using test methods detailed in AS/NZS 4420.1:2016
Windows, external glazed, timer and composite doors – Methods of test
Part 1: Test Sequence, sampling and test methods. This Standard sets out methods of test for determining the following performance aspects
of windows, external glazed, timber and composite doors
designed for installation in all classes of buildings:

AS/NZS 4420.1:2016 Clause 2 – Test sequence, sampling, and test methods.

AS/NZS 4420.1:2016 Clause 3 – Deflection Test, positive and negative wind pressures are applied
to the face of the window to test the maximum deflection under wind load. AS/NZS 4420.1:2016 Clause 4 – Operating Force Test, to verify that an opening sash is capable
of opening and closing without undue effort. AS/NZS 4420.1:2016 Clause 5 – Air In filtration Test, the air leakage of a window is tested to ensure
energy and acoustic efficiency. AS/NZS 4420.1:2016 Clause 6 – Water Penetration Resistance Test, to verify that no water leaks
through the window into the building. AS/NZS 4420.1:2016 Clause 7 – Ultimate Strength Test – negative and positive wind pressures
are applied to the window to at least 1.5 times the design wind pressure
to ensure it does not fail in unusual wind conditions. NZS 4211:2008 Appendix A – Torsional Strength of Sash Test – Projecting sashes are tested
with a torsional load to provide an indication of the likely smoothness of operation From this Wintec Systems can stay at the forefront of the industry
and continue to produce high quality aluminium window and door systems.
