1.5QUALITY ASSURANCE

A.Before delivery of glass and setting materials, certificates of conformance, or certified tests, in triplicate, attesting that the glass and setting materials and accessories meet the specified requirements, shall be accepted by the Architect-Engineer.

B.Definitions -

1.Thermal transmittance (or U-value), overall air-to-air thermal transmittance in Btu/hour-square foot-degree F, with an outdoor air temperature of 0 degree F, an indoor air temperature of 75 degrees F, and an outdoor wind velocity of 15 mph.

2.Shading coefficient, ratio of solar heat gain through a glass system to solar heat gain through a single light of double strength (1/8 inch thick) clear glass under the same set of conditions calculated with an outside air temperature of 89 degrees F, an outdoor wind velocity of 7.5 mph, an inside air temperature of 75 degrees F, and with a solar radiation intensity of 200 Btu/hour-square foot

C.Glass wind resistance -

1.Resist positive and negative wind loads for heights indicated - -For walls except corners -

2.27 psf up to 100 feet

D.For building corners -

1.Double positive and negative wind loads for walls -

-For purposes of wind load calculation, building corners are defined as vertical strips of 0.1 times least width of building

2.Calculate in accordance with ASTM E 1300

3.Use industry accepted strength multipliers for glass configurations other than annealed

If building corner wind loads are excessive for designated glass, improve glass wind resistance properties by heat strengthening or tempering instead of increasing glass thickness

4.Sealed insulating glass units, certified and permanently labeled Class C by manufacturer or licensee in accordance with ASTM E 774.

E.Silicone sealant -

-Adhere to metal and glass with adhesion strength equal or exceeding manufacturer's published value

-Compatible with gaskets, spacers, and setting blocks after 21 days exposure to ultraviolet radiation of 2000 to 4000 Microwatts

-Design stress of 20 psi using 6 to 1 safety factor

1.6DELIVERY AND STORAGE

ADeliver glass, setting materials, and accessories to site in original unopened containers or crates bearing manufacturer's name and brand. Delivered products, containers, or crates not having complete labels may be rejected.

BKeep materials dry preferably by storing on level platforms inside building. When necessary to store materials outside, stack off ground, supported on level platforms and fully protected from the weather, as accepted by Architect-Engineer, and /or DaimlerChrysler Corporation projected engineer.

CProtect reflective glass and insulating glass from damage caused by moisture, stress, and staining hazards during storage.
