This specification is for quality assurance water penetration testing only. The AAMA can be utilized if the project requires investigative testing. The AAMA was first released in and has had many changes over the years. The specification is for quality assurance water penetration testing only.

The AAMA guide provides specific details for testing procedures to ensure air and moisture penetration is minimized in newly installed fenestration systems.
The AAMA guide provides useful verbiage that can be directly inserted into project specifications, saving time and effort. It is up to the contractor to ensure these testing parameters are established. Additionally, the AAMA specifies that the water penetration resistance testing shall be performed by using the Procedure A method of the ASTM E , which is a consistent uniform static pressure for 15 minutes.
If interior finishes have been installed, they MUST be removed at the area of the test chamber to allow visual access to verify testing performance. The test specimen should be completely installed, adjusted, cleaned, and the perimeter sealed prior to testing. It is not recommended to notify anyone of the actual test locations until the testing agency arrives onsite. Typically, a sampling of areas from the project are selected and tested. The number of tests depends on the size and budget of the project.
With a large project, testing early on can prevent expensive repairs if a design flaw is identified during the first phase of testing. In case of leaks, the installer, waterproofing contractor, or the manufacturer will have an opportunity to make repairs to the test specimen, after which it will need to be re-tested. Normally, if a test specimen fails, the contractor should be prepared for additional testing.
Air and water leakage in that order are determined using a test chamber of constant pressure. A predetermined amount of air leakage is allowable. Any water present shall not extend beyond the plane parallel to the glazing intersecting the innermost projection of the test specimen.
All failures will be subject to further forensic investigation. The AAMA guide establishes the requirements for testing specimens, testing apparatus, and sampling procedures prior to the issuance of the building occupancy permit CO. If the building is occupied, and the installation is more than six months old, the AAMA method shall be used.
BDG utilizes professional testing equipment that is calibrated to each specific testing standard for accurate results. Our field consultants are properly trained and knowledgeable of all testing standards.
BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations. This allows us to not only properly test fenestrations on new construction projects, but also pinpoint the cause of any test failures and provide accurate recommendations to achieve successful testing results.
Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. If you are looking for a reputable second or third-party testing company to perform accurate professional testing, provide concise reports, and help you through the entire process, contact BDG today. We provide testing services throughout the United States from our headquarters located in Atlanta, GA.

The newly revised specification, titled "Voluntary Specification for Field Testing of Newly Installed Storefronts, Curtain Walls and Sloped Glazing Systems," establishes the requirements for test specimens, apparatus, sampling, test procedures and test reports to be used in evaluating the performance of installed storefronts, curtain walls and sloped glazing systems and their installation during construction, prior to issuance of the building occupancy permit, but no later than six months after issuance of the occupancy permit. Also excluded from this specification are commercial entrance systems. AAMA officials explain that verifying the structural loading resistance performance of storefronts, curtain walls and sloped glazing systems is beyond the scope of this specification.

Applicable Products: Applicable to curtain walls, storefronts, sloped glazing systems and window walls Test Procedure: The perimeter of the chamber is attached and sealed to adjacent frame members, concrete, structural steel or drywall at the top, bottom and sides of the specimen. The amount of airflow cfm required to maintain the pressure differential is recorded extraneous air leakage. Subsequently, the polyethylene sheet is removed from the exterior surface of the specimen. As a result, air infiltrating through the specimen changes the pressure inside the chamber.
