AS4420.5 Water Penetration Resistance Test – to verify that no uncontrolled water leaks through the window into the building.
AS4420.3 Operating Force Test – to verify that an opening sash is capable of opening and closing without undue effort.
AS4220.4 Air In filtration Test – the air leakage of a window is tested to ensure energy and acoustic efficiency.
AS4420.6 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.
