TestComm is pleased to offer window penetration testing to satisfy ASTM E1105 testing requirements.
As a companion to our building envelope testing, TestComm also provides ASTM E1105 testing for windows and curtain walls. This test method covers the determination of the resistance of installed exterior windows, curtain walls, skylights and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a static air pressure at the outdoor face higher than the the pressure at the indoor face.
This is accomplished by building an air chamber on the inside of the window and using a calibrated Retrotec DM32 controller and Retrotec Model 400 duct test fan to depressurize the inside of the window while spaying the outside of the window simultaneously.

Our spray racks are calibrated annually with an ultrasonic flow meter for precision flow rates.
