These test methods cover the ability of window assemblies of
various types to restrain, delay, or frustrate forced entry.
For purposes of these test methods, window assemblies are
defined as described in 1.2.1 – 1.2.5 and as shown in Fig. 1.Window
assemblies with a combination of operable sash and fixed panes
(lites) shall be classified and tested separately for each
Type A—A window assembly which incorporates one or more
sash that open by sliding, either vertically or horizontally within
the plane of the wall.
Type B—A window assembly which incorporates one or more
sash that are hinged at or near two corners of the sash and that
open toward the exterior (outswinging) or toward the interior
Type C—A window assembly which incorporates one or more
sash that are pivoted so that part of the sash opens toward the
interior and part of it opens toward the exterior.
Type D—A window assembly which incorporates one or more
fixed panes (lites) or stationary sash that are designed not to
Type E—A window assembly which incorporates a series of
overlapping horizontal louvers that are pivoted simultaneously by a
common actuator so that the bottom edge of each louver swings
outward and the top edge swings inward during operation.
