The following specification for installed aluminum windows references the ASTM E-1105, but falls short in specifying it's use in the construction of the facility. While there is reference to lab tests for the selected products, the assembly and its interface with surrounding materials is left to chance. Preventing water damage from uncontrolled leakage at openings needs to be part of every specification. Have you reviewed your current project to ensure FIELD TESTING is part of the process?
