Life cycle testing is optional on R, LC and CW rated products, but required for all AW rated products due to the increased stresses the product will encounter.
Testing: Testing the Window for Air Infiltration, Water Penetration, Uniform Structural & Operating Force
Cycle Test including Misuse: Comprised of both use and misuse operations that are completed many, many times to simulate approximately 7 years of use in the span of a day
Thermal Cycling: Cycles of extreme temperatures ranging from 0° to 180° F
Uniform Structural @ Design Pressure
Re-Testing: Repeat Air Infiltration, Water Penetration & Operating Force: Windows must pass the criteria accomplished the first time through
