Locating the sources of water leakage in existing building facades is challenging, time-consuming, and an ongoing annoyance to building owners. This paper proposes adaptation of existing testing methods to increase the effectiveness of testing for many of these issues. PPVs eliminate the need for interior test chambers, reduce setup costs, and allow for the testing of walls where conventional test chambers cannot be practically constructed. This paper demonstrates a procedure of utilizing up to 8 PPV fans, generating wind speeds ranging from 0—60 mph, and when combined with a calibrated spray rack, is capable of simulating realistic wind-driven rain conditions onsite. The ease of set up, flexibility, and the capability to control the start and stop of the leaks, makes this testing procedure a valuable tool for the forensic leak investigator. The authors look forward to other investigators improvements to our methods; and help to encourage ASTM to consider developing a new standard for its use.

Pixabay Public Domain. The American Architectural Manufacturers Association AAMA recently released an updated document to provide a standard water penetration test method when using dynamic pressure.
AAMA Included is a section on test equipment updated to clarify what to do for laboratory testing versus on-site testing. This is an advantage if the building is occupied or if constructing a chamber at the building site is not a practical option. Additional edits to this updated standard include the addition of two figures showing images of acceptable water leakage, plus a definition for what unacceptable water penetration means.

AAMA 501.1-17: Water Penetration of Windows, Curtain Walls and Doors Using Dynamic Pressure
The American Architectural Manufacturers Association AAMA recently released an updated document to provide a standard water penetration test method when it comes to using dynamic pressure.
