ORDINANCE NO. NS-1424 Page 21 glass that would ten~ to open the window while, simultaneously, an additional con- centrated load of 75 pounds is applied to the same area of the same sash member in the direction perpendicular to the plane of the glass towards the interior side of the window. With the load removed, apply the manipulation test described in Sub- section B, 3, 1, supra. With the sliding sash lifted upward to the full limit within the confines of the window frame, a concentrated load of 200 pounds shall be applied separately to each sash member incorporating a locking de- vice, at a point on the sash member within 6 inches of the locking device, in the direction parallel to the plane of the glass that would tend to open the window while, simultaneously, an additional con- centrated load of 75 pounds is applied to the same area of the same sash member in the direction perpendicular to the plane of the glass toward the exterior side of the window.~ With the load removed, apply the manipulation test described in Sub- section B, 3, 1, supra. For inside sliding windows, repeat Test f while simultaneously applying a concen- trated load of 25 pounds inward at the end of te movable bottom rail near the meeting stile opposite the lockstile. For outside sliding windows, repeat Test f while simultaneously applying a concentrated load of 25 pounds in the same direction as the perpendicular load inward at the end of the movable bottom rail near the meet- ing stile opposite the lock stile outward. h® Perform the disassembly and manipulation test as described in Subsection B, 3, m, supra. The tests for Type B and C window assemblies shall be performed in the following order: With the swinging sash in the normal posi- tion, apply a concentrated load of 100 pounds within 3 inches of each end of the rail or stile which is opposite the hinged side, in the direction perpendicular to the plane of the glass that would tend to open the window. Repeat Test a and simultaneously apply a concentrated load of 100 pounds on the outside within 1 inch of the end of the stile or rail which is opposite the hinged side, in a direction parallel to the plane of the glazing which would tend to dis- engage the lock.
