test in accordance with ASTM E330, and per the above- specified loads, shall not exceed L 1/175.

3. The deflection of a framing member in a direction parallel to the plane of glass, when carrying its full dead lad, shall not

exceed an amount which will reduce the glass or panel bite below 75% of the design dimension and the member shall

have a 1/8" minimum clearance between itself and the edge of the fixed panel, glass or component immediately adjacent,
