What is the AAMA 501.2 Test?

The AAMA 501.2 Quality Assurance Nozzle Test is a field water leakage check used in commercial construction to ensure storefronts, curtain walls, and sloped glazing systems are watertight. Water is sprayed at controlled pressure while technicians observe the interior for leaks, helping prevent costly water damage, mold growth, and structural issues. This test is crucial for building durability, occupant safety, and industry-standard compliance.

Test Methodology:

The AAMA 501.2 test is a field Quality Assurance and Diagnostic Water Check of installed storefronts, curtain walls, and sloped glazing systems. It simulates wind-driven rain to assess the building envelope’s watertightness.

Scope of Testing:

This test is a field quality assurance measure to ensure commercial glazing systems meet water resistance requirements and industry standards.

Products to Test:

Applicable to all storefronts, curtain walls, window walls, sloped glazing, skylights, fixed atriums, and other components designed to be watertight.

Test Procedure:

Using a calibrated spray wand held approximately 12 inches from the surface, water is applied at 30–35 PSI. Technicians observe interior areas for any water intrusion. Each section is thoroughly tested to ensure all joints, gaskets, and sealants are evaluated. All leaks are documented for quality assurance and repair.

Test Results:

The system either meets (passes) or does not meet (fails) performance criteria for water penetration resistance. Reports include detailed observations, leak locations, and recommendations for remediation if needed.

When should the AAMA 501.2 test be conducted?

Testing should be performed after installation but before interior finishes are complete to ensure early detection of leaks and compliance with building standards.

What products can be tested with AAMA 501.2?

Storefronts, curtain walls, window walls, sloped glazing, skylights, fixed atriums, and other watertight components can be tested. It does not cover operable windows and doors.

How long does the AAMA 501.2 test take?
