ASTM E1105-15 Testing

ASTM E1105-15: Field Water Penetration Testing

ASTM E1105-15 is the industry standard test method for determining the water penetration resistance of installed windows, curtain walls, skylights, and doors under uniform static air pressure. This procedure involves applying controlled water spray to the exterior of the building envelope while simultaneously subjecting it to pressure differences that simulate real-world wind-driven rain conditions. The test helps identify leaks, verify installation quality, and ensure compliance with performance requirements. This makes it a critical step in protecting buildings from costly water intrusion and long-term damage.

What to Expect with ASTM E1105-15

When you schedule ASTM E1105-15 testing with QED LAB, our team ensures the entire process is clear, efficient, and professional. Prior to testing, we’ll review project details, coordinate with onsite personnel, and set up the necessary spray racks, pressure chambers, and monitoring equipment. During the test, our technicians carefully simulate wind-driven rain conditions to evaluate the building envelope for any signs of water intrusion. You can expect our team to handle all preparation, execution, and documentation with precision, while keeping communication open so you know what’s happening every step of the way. Once complete, QED LAB provides detailed reporting to help you address potential issues and ensure your project meets specifications.

Frequently Asked Questions About ASTM E1105-15 Testing

What is ASTM E1105-15 testing?
ASTM E1105-15 is the standard method used to evaluate water penetration resistance of installed windows, curtain walls, skylights, and doors under simulated wind-driven rain conditions.
It helps confirm that fenestration systems perform as intended, prevents costly water intrusion issues, and ensures compliance with building codes, specifications, and warranty requirements.
Our team sets up spray racks to apply controlled water to the test area while simultaneously creating pressure differences with calibrated equipment to simulate real-world conditions. We then monitor for leaks or performance failures.
Minimal prep is required by your team. QED LAB handles setup, calibration, and operation. We may coordinate access, confirm installation readiness, and ensure utilities or water sources are available.
The duration varies depending on the size and number of test areas, but most ASTM E1105-15 tests can be completed in a few hours. QED LAB will provide an estimated timeline during scheduling so your project stays on track.
