BULLET-RESISTANT STEEL WINDOWS
**************************************************************************
NOTE: Bullet-resisting glazing materials may be
glass, plastic, or composite of the two. Edit out
all inappropriate items. Do not specify thickness
of glazing. Selection of no-spall criteria
generally requires use of plastic or composite
glazing materials. Therefore, if these options are
edited out, use low-spall criteria. Verify that
glass glazing, where required, is available to meet
low-spall criteria for threat specified.
**************************************************************************
Window assemblies shall be fabricated from [bullet-resistant steel shapes]
[or] [hollow metal with internal armoring] and bullet-resistant glazing
materials specified herein; the entire assembly shall meet or exceed the
specified regulatory requirements. Frames shall be welded units of sizes
and shapes indicated on the drawings with minimum frame face dimensions of
50 mm 2 inches. Glazing material shall be furnished with window assembly
for on-site installation, or windows shall be factory glazed units. Entire
assembly shall be furnished by same manufacturer. Exterior (attack side)
glazing stops shall be welded or integral to frame. Interior (protected
side) glazing stops shall be removable stops attached with high-strength
alloy steel machine screws with tamper-resistant heads.
2.7.1
Glazing Materials
Glazing material shall be factory fabricated units designed to be
bullet-resistant to the specified test standard in paragraph COMPONENT TEST
REQUIREMENTS. Glazing material shall be [glass,] [plastic,] [or]
[composite] with a [no-spall] [low-spall] protected (interior) face.
[Low-spall interior face shall meet or exceed requirements for spall
resistance defined in UL 752.] [No-spall interior face shall meet
requirements for spall resistance defined in HPW TP-0501.01.] Glazing
material shall conform to applicable requirements contained in ASTM C 1036,
ASTM C 1048, and ASTM E 1300. Glazing materials shall be tested in
accordance with the applicable sections of the following testing
procedures: ASTM D 905, ASTM D 1003, ASTM F 428, ASTM F 548, ASTM D 4093,
and ASTM F 520. All plastic glazing exposed to the interior or exterior
environment shall have an applied hardcoat.
2.7.1.1
Laminated Glass
Bullet-resistant laminated glass shall be all glass laminated construction
conforming to applicable sections of ASTM C 1172. The adhesive interlayer
material for bonding glass to glass shall be chemically compatible with the
SECTION 11035
