ASTM E1105: Determining the Resistance of Windows, Curtain Walls, Skylights, and Doors to Water Penetration
During ASTM E1105 field testing, water is applied to the outdoor face and exposed edges simultaneously with static air pressure. The ASTM E1105 testing can be applied to any curtain wall area or to windows, skylights, or doors alone. It is intended to determine the resistance to water penetration through specified building assemblies. If water does penetrate the assembly, but does not result in failure it may have ill effects on the performance of the materials, sealant, insulation, or laminated glass. However, ASTM E1105 is not used to address these issues or concerns.
