AAMA 502 Content And Requirements

Question 1

What defines the amount of water that may accumulate on an interior integral surface without being considered a failure in AAMA 502, 503?

Answer 1

There is no exception based on quantity of water. Failure is determined based on what part of the window leaks and where the water is discharged.

Question 2

Is water accumulation on a un-drained sill or meeting rail considered a failure according to AAMA 502?

Answer 2

No. As long as water does not pass beyond the innermost plane of the fenestration product, it is not defined as a failure by the standard.

Question 3

Should water penetration that does not constitute a failure be recorded in the report?

Answer 3

Yes. All points of water penetration during the test should be observed and noted.
