NOTE: Coordinate with paragraph Fragment
Resistance, under paragraph DESCRIPTION.
**************************************************************************
[The fragment shall be [_____] g ounces with a velocity of [_____] m/s fps
and impact [normal to] [at an angle of [_____] degrees measured from] the
door face.] [Protection from fragments shall be provided by steel plate
not less than [_____] mm inches in thickness.]
2.5.1.4
Rebound
**************************************************************************
NOTE: Coordinate with paragraph Rebound Resistance,
under paragraph DESCRIPTION.
**************************************************************************
Rebound resistance shall be [50] [100] [_____] percent.
2.5.1.5
Deformation Limits
**************************************************************************
NOTE: For structural steel doors, the deformation
limit criteria for accidental explosion applications
is given below.
Support
Prot. Cat. No.
Rotation (Deg.)
Ductility Ratio
1
2
10
2
12
20
A 2-degree support rotation and ductility ratio of 10 is recommended when
post-blast opening is required. This deformation limit is recommended
for conventional weapon and improvised weapon exterior door applications
in order to avoid entrapment of personnel.
**************************************************************************
The ductility ratio shall not exceed [10 and the support rotation shall not
exceed 2 degrees] [20 and the support rotation shall not exceed 12 degrees].
2.5.1.6
Hardware
**************************************************************************
NOTE: Coordinate with paragraph Hinges, under
paragraph HARDWARE. A door pull is recommended.
**************************************************************************
Full surface hinges shall be Type [1] [2] [3]. [Multiple] [Jamb] latching
points and [multiple lever handles] [,] [or] [a single lever handle] [,]
[or] [a wheel handle] [,] [or] [a spoke lever handle] operated from [the
seating face] [and] [opposite the seating face] with [manual]
[self-latching] latch engagement and [either] sliding [or lever] latch
bolts shall be provided. The latching mechanism shall be [safety] [or]
[cover] plated. A [Type [I] [II] [III] straight steel bar door pull] [,]
[and] [padlock] [shrouded padlock] [,] [and] [hasp] [high security hasp]
[shrouded hasp] [,] [and] [door stop] [,] [and] [surface door closer]
[overhead door holder] [,] [and] [gasket seals] [door silencer] [,] [and]
[optical device] shall be provided.
