NOTE: For reinforced concrete doors, the
deformation limit criteria for accidental explosion
applications is given below.

A support rotation of not more than 2 degrees 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 door support rotation shall not exceed [1 degree] [2 degrees] for
one-way acting doors without stirrups, [2] [4] degrees for one-way acting
doors with stirrups, and [2] [8] degrees for two-way acting doors.] [The
support rotation shall not exceed 2 degrees except that the support
rotation for one-way acting doors without stirrups shall not exceed 1
degree.]
2.5.2.6
Hardware
Hinges shall be Type 2. [Multiple] [Jamb] latching points and multiple
lever handles operated from [the seating face] [and] [opposite the seating
face] with manual latch engagement and lever latch bolts shall be provided.
Type [I] [II] [III] straight steel bar door pull [,] [and] [padlock]
[shrouded padlock] [,] [and] [hasp] [high security hasp] [shrouded hasp]
[,] [and] [door stop] [,] gasket seals [, and optical device] shall be
provided.
2.5.2.7
Operating Forces
**************************************************************************
NOTE: Coordinate with paragraph Blast Door
Operation, under paragraph DESCRIPTION.
**************************************************************************
Maximum operating forces shall be [180] [_____] N [40] [_____] pounds to
set the door in motion and [90] [_____] N [20] [_____] pounds to swing the
door. Maximum force to engage and release latches shall be [135] [_____] N
[30] [_____] pounds.
