Viwinco Testing Lab: Intro to Standard Window Testing /Structural Test

Описание: The structural test measures a window's ability to withstand air pressure, which is calculated in pounds per square foot. AAMA uses a table that converts pounds per square foot to wind speed. The window is tested with both positive and negative pressure, which simulates real-life conditions. As a built-in engineering safety margin, the test pressure used is 1.5 times its targeted design pressure. In order for the window to pass, it must maintain its structural integrity without breakage throughout the course of the test. When testing at the commercial window performance class and above, deflection limitations are also part of the test.
