(Opaque and Transparent); Test Procedures and
Acceptance Criteria," HPW TP-0502.01. On opaque
portions of the assembly, the time is 15 or 60
minutes against attack tools similar to the "low
forced entry severity level." However, note that on
transparent portions, sharp-edge cutting tools are
specifically exempted from the test tools. The
tests include a vigorous attack by six persons.
Ballistic tests may be performed on the same samples
before the forced entry testing, and without
changing or repairing damaged assemblies, in
accordance with HPW-TP-0501.01, "Ballistic
Resistance of Structural Materials (Opaque and
Transparent); Test Procedures and Acceptance
Criteria."
f. "Transparent Materials and Assemblies for Use in
Forced Entry or Containment Barriers," HPW
TP-0500.03. This standard was developed by H. P.
White Laboratories for commercial, governmental, or
military application and generally is used in
testing prison (forced exit resistant) components.
This test method defines two of three factors (tools
and techniques) and varies the third factor (time)
to establish five levels of forced entry resistance.
Levels I, II, III, IV, and V specify attack tools
and sequences of attacks with the specified tools.
Attack weapons and tools include hand tools, propane
and acetylene torch, chemical solvents, and five
levels of ballistic assault. The ballistic threats
are considered integral to the forced entry rating
in this standard and differ from those in other H.
P. White standards. Tests are conducted on either a
915 x 1220 mm (3 x 4 foot) specimen of transparent
material or on a complete assembly.
3. International Conference of Building Officials,
"Tests for Window Assemblies," UBC 41.2. Describes
the following tests which are related to security
windows: hand manipulation, tool manipulation,
static load, and locking device tests. This testing
is at a level comparatively below the "very low
forced entry severity level."
4. National Institute of Justice (NIJ). "Physical
Security of Window Units," NIJ 0316.00-80. Use of
the NIJ standard for Army application is limited
because it describes construction types which have
been demonstrated to have minimal penetration times
against the more sophisticated threats. This
specification describes four classes of physical
security by describing the window types indicated
below. This testing is at a level comparatively
below the "very low forced entry severity level."
a. Class I (Grade 10)--minimum level: Regular
glazing in commercial sash; double locks; wood frame
acceptable.
