This specification is for quality assurance testing only. See our page for further information. This specification is for quality assurance testing only of storefronts, curtain walls and sloped glazing systems and their installation.

It can only be utilized prior to the issuance of the building occupancy permit and no later than six months after the installation of the fenestration product. Specifically excluded from this specification are asmt, glass doors and skylights. These systems shall be tested per the AAMA The diagnostic field water check is utilized for installed storefronts, curtain walls and sloped glazing systems only.

This atm water check method is not intended to test the rated or specified water performance representative of a wind driven rain event.

The AAMA is the proper test method for field testing of storefronts, curtain walls and sloped glazing for air leakage resistance and water penetration resistance performance. Specifically excluded from this field check method is the testing of operable components such as operable window and doors.

The purpose of this voluntary guideline is to recreate leaks that are known to occur.

This differs greatly from the AAMA and AAMA field testing procedures that are intended for evaluating newly installed fenestration products or quality assurance testing. The main objective of forensic water testing is to identify the leak paths through the simulation of asmt weather events that produced the reported leakage.

The AAMA describes steps for calculating the approximate differential air pressures the specimens experienced during actual wind driven rain events.

This standard is utilized for laboratory or interior mock up testing only.

ASTM E331 – 00(2016)

This test method exclusively utilizes a uniform static air pressure difference. This standard is utilized for either field quality assurance testing or forensic testing. ASTM states that the field test may be made at the time the window, skylight, curtain wall ast, door assemblies are initially installed. Which would be referred to as quality assurance testing. ASTM states the field test may also be made after the building is completed and in service to determine whether or not reported leakage problems are due to the failure of the installed assemblies.


Water Penetration Field Testing

There are two different procedures listed for the test method. SITC determines what procedure to utilize based on the laboratory testing results. This starts with a clearly defined sequence of activities that SITC follows during a investigation: The evaluation of the design concept to determine if any water resistance performance requirements were specified for the wall.

The determination of the service history of the building to provide patterns in the observed leakage and visible damage and where to focus our investigation. Conducting the investigative testing to verify and extend hypotheses arrived at during the axtm review and inspection portions of the investigation using controlled and reproducible procedures.

Water Penetration Field Testing

Analyzing the data and establishing a cause and effect relationship between wall characteristics and the observed leakage. ASTM E references the following documents: Procedure A is a uniform static air pressure difference.

Procedure B is a cyclic static air pressure difference. The reviewing of project documents for the building. Read more about what our customers have to say
