and allows a third factor (duration) to vary in
order to establish severity levels of forced entry.
Assemblies to Forced Entry, Excluding Glazing", ASTM
F 588. This specification applies to window
assemblies of various materials and types of
construction. Five window types are classified.
The tests are intended to establish a measure of
resistance to attack by unskilled or opportunistic
burglars. Tests include hand manipulation, tool
manipulation, static load, and locking device
strength resistance. This testing is at a level
comparatively below the "very low forced entry
severity level."

H. P. White Laboratories
a. "Forced Entry Resistance of Security Structures
and Structural Subassemblies, Very Low Threat
Level," HPW TP-0506.00. This standard represents
the Army "very low forced entry severity level." The
attack times are 5, 15, and 60 minutes using limited
tools. The test includes a vigorous attack by two
active attackers on a material specimen or a
complete assembly.
b. "Forced Entry Resistance of Security Structures
and Structural Subassemblies, Low Threat Level," HPW
TP-0507.00. This standard represents the Army "low
forced entry severity level." The attack times are
5, 15, and 60 minutes using unlimited hand tools.
The test includes a vigorous attack by three active
attackers on a material specimen or on a complete
assembly.
c. "Forced Entry Resistance of Security Structures
and Structural Subassemblies, Medium Threat Level,"
HPW TP-0508.00. This standard represents the Army
"medium forced entry severity level." The attack
times are 5, 15, and 60 minutes. The test includes
a vigorous attack by four active attackers on a
material specimen or on a complete assembly. The
attack uses unlimited hand tools, limited power and
thermal tools, a hand-held hydraulic jack, and
weapons.
d. "Forced Entry Resistance of Security Structures
and Structural Subassemblies, High Threat Level,"
HPW TP-0509.00. This standard represents the Army
"high forced entry severity level." The attack
times are 5, 15, and 60 minutes. The test includes
a vigorous attack by four active attackers on a
material specimen or on a complete assembly. The
attack uses unlimited hand and power tools, limited
thermal tools, a hand-held hydraulic jack, weapons,
