This guide illustrates test procedures to ensure air and moisture penetration is minimized in new window installations. In addition, the AAMA guide provides verbiage that can be directly inserted into project specifications, saving time and effort. The only problem with the verbiage provided is that it is often inserted in a generic format that does not provide details as to the areas, quantity, and specific testing pressures. It is up to the contractor to ensure these testing parameters are established. Once testing parameters are specified, the testing agency ensures that proper procedures were followed during the construction installation process. Typically, a sampling of windows from the project is selected and tested.

BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations. What is the drainage design? 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. This field check is not appropriate for testing operable components.
A specified pressure is maintained while any escaping air is measured. The number of tests depends on the size and budget of the project. It is up to the contractor to ensure these testing parameters are established. In addition, the AAMA guide provides verbiage that can be directly inserted into project specifications, saving time and effort. Water penetration observed when testing windows will be given extra attention for the remainder of the project. Building Diagnostics Group, Inc.
One-week notice prior to water testing is usually given to all construction crew members concerned with window installation. This field check procedure is only intended to evaluate joints, gaskets and sealant details in the glazing which are designed to remain permanently closed and water tight.
The Requirement of AAMA accreditation assures the specifier that the laboratory has the staff, training, experience and calibrated equipment to properly perform field testing. The AAMA was first released in and has had many changes over the years. Water leakage uses the same method while spraying the window from outside to observe indoor penetration. Give us a call to discuss your next project.
Our field consultants are properly trained and knowledgeable of all testing standards. The construction contract will appoint a party responsible for the cost of the testing. The project architect, manager, or owner specifies the amount and locations of the windows to be tested; this happens either early in the project or at three intervals in the case of large projects: Typically, a sampling of windows from the project is selected and tested. Are the edges perfectly horizontal and vertical?
See our AAMA page for additional information. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. A predetermined amount of air leakage is allowable; however, no water leakage is permitted at all. It has become the gold standard for all water penetration resistance testing conducted in the United States regards to fenestration products such as windows, doors, and skylights.
Member discount will be reflected after successful login to the Checkout process. Begin your publication search by entering information into the fields below. This guide illustrates test procedures to ensure air and moisture penetration is minimized in new window installations. Testing shall be performed by an AAMA accredited independent testing agency.
The AAMA can be utilized if the project requires investigative testing. It is primarily used for new construction quality control and assurance purposes. If you have any questions pertaining to field testing specifications on your aamma, or simply need a quote, do not hesitate to call or email anytime and we would be glad to assist you the best we can. See our AAMA page for additional information if your project requires to test for the rated air leakage or rated water penetration performance.
With a project, testing early on can prevent expensive repairs if a design flaw is identified during the first phase of testing. The specification is for quality assurance water penetration testing only. American Architectural Manufacturers Association. The objective of forensic water spray testing is to identify and track the water migration through the simulation of wind rain events.
Any moisture not coming in through the window, but getting in somehow, will be subject to further forensic investigation. Search by product code or category or leave the product code field blank to see a list of all AAMA publications. Normally, if a window fails, the contractor should be prepared for a wider scope of testing.

AAMA 502-12: Field Testing of Newly Installed Fenestration Products
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.
AAMA 502 08 PDF
Test procedures and test reports to be used in verifying the air infiltration resistance performance and water penetration resistance performance of newly installed fenestration products. Applicable Products: Applicable to newly installed windows and doors. 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. Adjustments are made to the test equipment to maintain the pressure differential, and the increased airflow is recorded total airflow.
