The whole area must be covered with glass for the work to be finished. You must carefully follow the approved shop drawings and job specs when doing this work. An area of the finished part will be chosen by the architect and/or the owner’s representative to be tried.

The test area should be a good example of normal construction, and shouldn’t have any obvious flaws or items still on the “punch list.” If a test area and/or site has not been chosen, the people who are giving the test will choose one. This area, normally at least 9.3 m2 (100 ft2), will be chosen to provide accurate performance data. There should be border caulking, standard splices, frame intersections, and, if needed, at least two full vision lites and two full spandrel lites with an intermediate vertical member and an intermediate horizontal member in the area that needs to be tested. In the test area, all parts that can work must be separated and not put through the test process.

All framing and/or units shall be installed on the lower two typical floors of the building for curtain wall testing and on the lowest typical floor for storefront or sloped glazing system testing. The area shall be fully glazed to provide a completed installation.

All of this work shall be done in strict accordance with approved shop drawings and job specifications. The architect and/or owner’s representative shall designate an area of the completed portion to be tested. The test area shall be a representative sample of typical construction and shall have no outstanding punch list items or other visible defects. If no test area and/or location has been identified, the persons doing the test shall select an area. This area shall be selected to provide representative performance data, usually a minimum of 9.3 m2 (100 ft2).

The area to be tested shall include perimeter caulking, typical splices, frame intersections, and, if applicable, at least two entire vision lites and two entire spandrel lites containing an intermediate vertical member and an intermediate horizontal member. All operable components within the test area shall be isolated and exempt from the test procedure.
