SECTION 5:
BALLISTIC RESISTANT GLAZING
5.1
Introduction.  This section provides two procedures to
analyze the resistance of glazing systems against ballistic
attack.  The first is the Ballistic Resistant Glazing Evaluation
Procedure.  Use it to evaluate existing windows.  The second is
the Ballistic Resistant Glazing Selection Procedure.  Use it to
select glazing systems for new construction and to retrofit
existing facilities.
5.2
Levels of Protection to Resist Ballistic Attack.  There
is one level of protection to resist a ballistic attack.  This
level is referred to as high level of protection for consistency
with Army TM 5-583-1.  Table 4 provides a summary of the
protective measures for this level of protection. Refer to Table
D-30 for design parameters associated with each of the threat
severity levels for ballistic attack.

1. Provide glazing system to resist threat
severity level.
2. Minimize number and size of windows.
5.3
Ballistic Resistant Glazing Evaluation Procedure.  This
procedure helps to evaluate the performance of an existing
glazing system subjected to ballistic attack.  It provides a set
of structures that step an analyst through the process of
comparing existing glazing materials with materials known to
resist specific levels of ballistic attacks.  A process chart and
description of the procedure are shown in Figure 16 and Figure
17, respectively.
