2.5 SOURCE QUALITY CONTROL

2.5.1 Window Assembly Structural Test

2.5.1.1 Test Sample Number

At least two sample window assemblies for each type of window provided shall be tested, under an increasing uniform static load. Number of samples, beyond two, is left up to the vendor. However, it is noted that the acceptance criteria encourages a larger number of test samples.

2.5.1.2 Test Procedure

Test windows (glass panes and support frame) shall be identical in type, size, sealant, gasket or bead and construction to those furnished by the window manufacturer. The frame assembly in the test setup shall be secured by boundary conditions that simulate the adjoining walls of the structure for intended installation. The simulation securing boundary conditions shall be verified and attested by an attending Professional Engineer. Using either a vacuum or a liquid-filled bladder, an increasing uniform load shall be applied to the entire window assembly (glass and frame) until failure occurs in either the glass or frame. Failure shall be defined as either breaking of glass or loss of frame resistance. The failure load, rf, shall be recorded to three significant figures. The load should be applied at a rate of 0.5 ru per minute where ru is the static design resistance.

2.5.1.3 Acceptance Criteria

The static load capacity (rs) of a glass pane for the specified acceptance test procedure is:

SECTION 08 56 53 Page 5 rs = 0.876 ru (1)

The window assembly (frame and glass) is considered acceptable when the arithmetic mean of all the samples tested, r- such that:

r- => rs plus sA (2) where: rs = static load capacity of the glass pane for certification testing s = sample standard deviation A = acceptance coefficient (Table 1)

a. Arithmetic mean/standard deviation: For n test samples, r- is defined as:

r- = sum from i = 1 thru n for rfi divided by n (3 ) where rfi is the recorded failure load of the ith test sample.

The sample standard deviation, s, is defined as:

s = the square root of the quantity of the sum from i = 1 thru n for (rfi

- r-2) divided by (n - 1) (4)

The minimum value of the sample standard deviation, s, permitted to be employed in Equation (2) is:

s = 0.145 rs (5)

This assures a sample standard deviation no better than observed for the general population of tempered glass.

b. Additional sampled determination: The following equation can be used by tester to determine if additional test samples are justified. If:

r- =< rs plus sB (6) then with 90 percent confidence, the design will not prove to be adequate with additional tests. Obtain rejection coefficient, B, from Table 1.

PART 3 EXECUTION

3.1 INSTALLATION

3.1.1 Method of Installation

Install in accordance with the window manufacturer's printed instructions and details. Set windows at proper elevation, location, and reveal.

Brace properly to prevent distortion and misalignment. Bed screws or bolts in sill members, joints at mullions, contacts of windows with sills, built-in fins, and subframes in mastic sealant of a type recommended by the window manufacturer. Install windows in a manner that will prevent entrance of water. Fasten hardware to windows.

3.1.2 Glass Setting

Items to be glazed shall be either shop or field glazed using glass of the quality and thickness specified or indicated. Preparation and glazing, unless otherwise approved, shall conform to applicable recommendations in the GANA Glazing Manual . Windows may be glazed in conformance with one of the glazing methods described in the standards under which they are produced, except that face puttying with no bedding will not be permitted. Handle and install glazing materials in accordance with manufacturer's instructions. Use beads or stops furnished with items to be glazed, to secure glass in place. Apply structural silicone bead to the inboard side only for insulating glass units.

3.1.3 Dissimilar Materials

Where aluminum surfaces are in contact with, or fastened to, masonry, wood, or dissimilar metals, except stainless steel or zinc, the aluminum surface shall be protected from dissimilar materials as recommended in the Appendix to AAMA/WDMA/CSA 101/I.S.2/A440 . Do not coat surfaces on which sealants are to adhere.

3.1.4 Anchors and Fastenings

Make provision for securing units to each other and to adjoining construction.

3.2 CLEANING

Clean interior and exterior surfaces of window units of mortar, plaster, paint spattering spots, and other foreign matter to present a neat appearance, to prevent fouling of weathering surfaces and weatherstripping, and to prevent interference with the operation of hardware. Remove stained, discolored, or abraded windows that cannot be restored to their original condition, and replace with new windows.
