Standard: ASTM E1105-15 – Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Wall by Uniform or Cyclic Static Air Pressure
Scope: 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 pressure at the indoor face.
Applicable Products: Applicable to curtain walls, windows, skylights, window walls and doors.
ASTM E1105, Procedure A – Water penetration testing is conducted at the specified air pressure differential while simultaneously spraying water on to the exterior face of the assembly at the required rate of 5 gph/ft2. During testing, the interior face of the test area is inspected for water leakage. Testing continues for 15 minutes.
ASTM E1105, Procedure B – Water penetration testing is conducted at the specified air pressure differential. Four cycles are employed during the test unless otherwise requested. Each cycle consists of 5 minutes with the air pressure applied and 1 minute with the air pressure released. Water is applied continuously at the required rate of 5gph/ft2. During testing, the interior face of the test area is inspected for water leakage.
End Result: Upon the completion of a successful test, the product meets the performance criteria for water penetration resistance or does not meet criteria and further remediation may be required to pass.
