NOTE: Delete the latch operating force sentence
when a mortise lock and latch set or exit device is
specified.
Coordinate with paragraph Blast Door Operation,
under paragraph DESCRIPTION.
**************************************************************************
[Maximum operating forces shall be [90] [_____] N [20] [_____] pounds to
set the door in motion and [70] [_____] N [15] [_____] pounds to swing the
door.] [Operating forces shall conform to NFPA 101.] Maximum force shall
be [90] [_____] N [20] [_____] pounds to engage and release latches.

TESTS, INSPECTIONS, AND VERIFICATIONS
2.6.1
Prototype Static Test
**************************************************************************
NOTE: Retain this paragraph when overpressure is
specified without duration.
**************************************************************************
Static tests on prototype door assemblies shall demonstrate that the door
will resist the blast overpressure. Static tests will be accepted only if
the door and frame proposed are manufactured using the same materials,
dimensions, and tolerances as those in the prototype static test and the
static overpressure used in the test is at least two times the blast
overpressure. Static test reports shall be supplemented with calculations
that demonstrate rebound resistance when rebound is not tested.
2.6.2
Prototype Blast Test
Blast tests on the prototype door assembly shall demonstrate that the door
will resist the overpressure waveform. Blast tests will be accepted only
if the door and frame proposed are manufactured using the same materials,
dimensions, and tolerances as those in the prototype blast tests. The rise
time of the test waveform shall be zero or subject to approval. [For an
overpressure with infinite duration, the overpressure used in the test
shall be not less than that specified or indicated for a duration equal to
at least five times the natural period of the door and the test report
shall be supplemented with calculations that demonstrate the specified or
indicated rebound resistance.] [For overpressure with finite duration, the
overpressure waveform used in the test shall exceed the overpressure
waveform in both peak overpressure and impulse and the blast test report
shall be supplemented with calculations that demonstrate the specified or
indicated rebound resistance when the positive phase waveform duration in
the test exceeds the positive phase duration specified or indicated.]
2.6.3
Shop Operating Test
Prior to shipment, each door assembly shall be fully erected in a
supporting structure and tested for proper operation. Such testing shall
include opening, closing, and operating all moving parts to ensure smooth
operation and proper clearance, fit, and seating. The operating forces and
opening and closing times shall be determined. The Contracting Officer
