AAMA 501.2 Window Water Testing in Los Angeles | San Francisco | San Diego
The AAMA 501.2 Window Water Testing procedure, provides quality assurance. We provide this field water penetration test performed on Storefront windows, curtain wall as well as sloped glazing systems alike.
Looking for window water leaks
On that note, the AAMA 501.2 test that we perform in Los Angeles, San Francisco, and San Diego is not a test designed for newly installed fenestration products that are operable. AAMA has a test for this and its the AAMA 502. Otherwise, for exceptional weather events or conditions, you may want to opt for the AAMA 502, 503 or the ASTM E1105 methods. Along the same lines, AAMA 511-08 is reserved for forensic testing of fenestration products.
What’s in the scope of the AAMA 501.2-15?
When testing to the 501.2 we are essentially evaluating joints, gaskets and sealant applications within the glazing system. Furthermore, this test on these components are to be used on fenestration product which are permanently closed, sealed and water tight. That is, as opposed to operable systems like doors and windows which open.Prior to Performing the AAMA Test
A few things to consider prior to performing any AAMA 501.2-15 Los Angeles Window Water Testing. Make note that all of the fenestration products to be tested are to be completely installed. And, installed in accordance with approved drawings. Additionally, the window products to be tested cannot possess and defects nor shall there be any outstanding “punch-list” items to be corrected. All of that stuff has to be completed prior to us arriving to the site for testing.
When sampling area for testing, the areas should be no less than 100 ft2 and include the entire frame testing. So basically we’re testing the caulking, splices and intersections of the window product. Should there be any operable components within the specimen, those components have to be isolated from the test. We do this so that part of the specimen does not receive water.
Equipment used to perform the AAMA 501.2 test
If you’re a seasoned contractor, you’re probably familiar with this test. If you’re new to this test, you might find it odd that there isn’t a calibrated spray rack. The Calibrated spray rack is widely used throughout other AAMA and ASTM water intrusion tests.
The AAMA 501.2-15 Window Water Testing is, however, very specific in the nozzle used and the method by which water is applied onto the specimen.
Take the Nozzle for example. The specific nozzle used is manufactured by one company in the US and is specific to this test. Water pressures for this test are to be valve adjusted to a pressure of 30-35 psi displayed by a “calibrated” gauge. Even the water hose diameter is suggested. In some cases water pressures have to dip below this standard number. There is an exception written into the 501.2 which allows a reduction to 25 lbs as quoted here;
Special Notes for the AAMA 501.2-15 Los Angeles Window Water Testing method
NOTE 3: This test method may be conducted at pressures lower than 205 kPa (30 psi) providing that the reason (i.e. not practical at a multistory building location) for not achieving this pressure is 1) acceptable to the specifier, 2) the pressure is not lower than 170 kPa (25 psi) and 3) the reason and the actual pressure are so noted in the test report as an exception to the method.
Application of the AAMA 501.2-15 Los Angeles Window Water Testing
Once the testing starts, the operator will divide the tested areas into five-foot sections. When applying water onto the specimen the wand is held no less than one foot away from the tested surface. The wand is then moved in a back and forth motion, slowly across the specimen.
Moreover, the water applied is at a rate of one foot per minute. So there is no guess-work involved on the operator’s part. The too we use has a special attachment which keeps it at the specified setback of one foot.
During this test, a test technician is located inside the building armed with a flashlight and water indicating paper. Their primary job is to identify any water intrusion into the building as a result of the testing performed.
Reporting
After all, testing is completed a report is generated and issued. Our test reports will include the date and time of the test and the manufacturer’s fenestration model, material and dimensions.
We’re sure you’ll find our reports extremely clear and easy to understand. We document the condition of any specimen tested. This also includes their placement within the building.
Results from the tests show any water intrusion from primary or secondary testing if secondary testing was provided. The proximity of any leaks within the specimen or area is documented as well.
Our testing methods and procedures follow the AAMA 501.2-15 Window Water Testing procedure to the letter. Which is to say, as a third-party testing agency, our only job is to ensure the tests performed are administered exactly as specified in the AAMA document without deviation or opinion.
