Why should anyone care about ASTM E1105? The answer is simple: water penetration can compromise the integrity of your structure, leading to costly repairs and a shorter lifespan. ASTM E1105, the Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, is a crucial guideline that helps ensure these components are up to the task of resisting water infiltration.
Preliminary Examination
Before we begin testing, we conduct a preliminary visual examination of the assembly. This initial assessment allows us to identify evident signs of damage or failure, if any, prior to engaging in physical testing of the unit. Should we detect indications of wear and tear suggesting potential water leakage, we will promptly bring it to our client’s attention.
Assuming the assembly is functioning properly we will proceed to test its fundamental functions, such as opening, closing, and latching. Simultaneously, we scrutinize the adjacent wall and/or roof to ensure the assembly's proper installation adheres to ASTM E2112 standards. All observations from this examination are meticulously documented in the final report, specifically the E1105 – Field determination water penetration testing for windows, doors, and curtain walls report.
Test Chamber
Testing
Prior to testing, a test chamber is created around the interior side of the assembly. This chamber serves to isolate the assembly from the remainder of the building interior while keeping joints and surfaces unobstructed for observation.
Static Air Pressure:
In the static air pressure method, the air pressure is established within the test chamber. Subsequently, the spray rack directs water at the assembly for a minimum duration of 15 minutes. We meticulously document any water penetration observed during and immediately after the testing.
Cyclic Static Air Pressure:
With the cyclic air pressure method, the test chamber air pressure is initially set, and water is directed at the assembly for five minutes. The air pressure inside the test chamber is then reduced to zero for one minute before being restored to the original setting. This cycle repeats three to five times. Once again, any water penetration observed during or immediately after the testing is documented.
Rain Maker
Testing Equipment
Rain Maker:
A water spray grid is positioned on the outside of the assembly and directs 5.0 U.S. gal/ft2·h (3.4 L ⁄m2·min)” at the assembly.
Air Control System:
Measures the amount of air pressure in the chamber.

Reporting
Following the testing, our BES team will create a comprehensive report based on ASTM E1105 – Field determination water penetration testing. This report will encompass various aspects, including details such as the window location, type, manufacturer, and the make/model of each tested assembly. A standard compliance statement will be included, along with the incorporation of thermography in the report. Furthermore, the report will provide descriptive information about the condition of the assembly during testing, its operational status, and may include a visual breakdown of the assembly.
After testing, our Building Envelope Science (BES) team will create a detailed report based on ASTM E1105 for water penetration testing. This report will include important details such as window locations, types of windows tested, manufacturer information, and the specific make and model of each assembly. It will also have a compliance statement to confirm adherence to industry standards, along with thermography insights. Additionally, the report will describe the condition of the assembly during testing, its operational status, and may include visuals for better understanding.
GRLA’s experienced BES team regularly conducts ASTM E1105 field tests for a variety of clients. With a deep understanding of water penetration risks, we help ensure that windows, doors, and curtain walls perform reliably against the elements. Reach out if we can help you!
