AAMA releases document on recommended static water penetration resistance test pressures

July 15, 2013 – The American Architectural Manufacturers Association has published a document that recommends static water penetration resistance test pressures for non-hurricane-prone US regions. AAMA TIR A13-13, Recommended Static Water Penetration Resistance Test Pressures in Non-Hurricane-Prone Regions of the United States was prepared for those who require information on maximum static pressures used during testing of products’ resistance to wind-driven rain penetration, when such tests are conducted as part of the North American Fenestration Standard (NAFS) test regimen.

July 15, 2013 – The
American Architectural Manufacturers Association has published a document
that recommends static water penetration resistance test pressures
for non-hurricane-prone US regions. AAMA TIR A13-13, Recommended Static
Water Penetration Resistance Test Pressures in Non-Hurricane-Prone Regions
of the United States was prepared for those who require
information on maximum static pressures used during testing of products’
resistance to wind-driven rain penetration, when such tests are
conducted as part of the North American Fenestration Standard (NAFS) test
regimen.

“Resisting wind-driven rain penetration is one of the primary functions of
fenestration systems and is addressed by many industry standards, building
codes and project specifications,” says Steve Fronek
(Apogee Enterprises, Inc./Wausau Window and Wall Systems), co-chair of the
TIR A13-09 Update Work Group. “The 12 psf (580 Pa) water penetration
resistance test pressure cap cited in NAFS has served all industry stakeholders
well for more than 20 years and is recommended for general use outside of
high velocity wind zones for low- and mid-rise construction in
the U.S. When specified as part of the NAFS test regimen, it represents a
solid trade-off between cost, performance, aesthetics and functionality
for most construction projects.”

AAMA TIR A13 is not intended to validate or quantify the statistical
repeatability or reproducibility of any test method or to recommend new or
revised test methods.

AAMA TIR A13 references important industry standards which include:
* AAMA 502-12, Voluntary Specification for
Field Testing of Newly Installed Fenestration Products
* AAMA 511-08, Voluntary Guideline for
Forensic Water Penetration Testing of Fenestration Products
* AAMA GS-001-84, Voluntary Guide
Specification for Aluminum Architectural Windows
* ASCE/SEI 7-10, "Minimum Design Loads for Buildings and Other
Structures"

Test Pressures in Non-Hurricane-Prone Regions of the United States may
