SOURCE QUALITY CONTROL
Test of HEMP shielded door at factory will require shielded room. Factory
test of HEMP shielded door shall comply with requirements of this
specification and MIL-STD-188-125. Government reserves the right to
witness all factory tests. Provide [30] [_____] days notice for test
performed in Continental United States and [45] [_____] days for overseas
locations. Conduct the swinging door static load test, swinging door sag
test, door closure test, and handle pull test on each door of each size and
each type provided including electromagnetic type. Use the HEMP filter(s)
with surge arrestors, card access system, control panel, alarm panel,
cipher or combination lock(s), and any other hardwares to ensure the entire
system meets the specification requirements. Submit a Test Plan for the
test specified herein."
2.9.1
Swinging Door Static Load Test
Mount and latch swinging HEMP shielded door to its frame and then set down
in a horizontal position so that the door opens downward and only the frame
is rigidly and continuously supported from the bottom. With door closed,
apply a load of [195] [_____] kg/m2 [40] [_____] pound per square foot
uniformly over the entire surface of the door for at least [30] [_____]
minute. Door will not be acceptable when this test causes breakage,
failure, or permanent deformation that results in the clearance between
door leaf and stops to vary more than 1.58 mm 1/16 inch, or reduction of SA
by 5 dB. This test shall be performed on all door types, including
electromagnet type. The same door leaf shall be subjected to the door
closure, handle pull and door sag tests.
2.9.2
Swinging Door Sag Test
Install HEMP shielded door and its frame normally and open 90 degrees.
Suspend two [45.4] [_____] kg [100] [_____] pounds weights from door, one
on each side of door, within [125] [_____] mm [5] [_____] inches of the
outer edge for at least [30] [_____] minutes. Door will not be acceptable
when this test causes any breakage, failure, or permanent deformation that
results in the clearance between door leaf and door frame to vary more than
1.58 mm 1/16 inch from its original dimension, or reduction of SA by 5 dB.
This test shall be performed on all door types, including electromagnet
type.
2.9.3
Door Closure Test
Operate HEMP shielded door of each size, type, design [10,000] [_____]
complete open-close cycles. HEMP shielded door will not be acceptable when
this test causes any breakage, failure, or permanent damage or deformation
that results in clearance between door and frame to vary more than 1.58 mm
1/16 inch from its original dimension, or reduction of SA by 5 dB. This
test shall be performed on all door types, including electromagnet type.
2.9.4
Handle Pull Test
Mount and latch HEMP shielded door to its original frame. Apply a force of
[1112.5] [_____] Newton [250] [_____] pound perpendicular (outward) to
handle within [50] [_____] mm [2] [_____] inch of the end for at least [30]
[_____] minutes. Door will not be acceptable when this test causes any
breakage, failure, or permanent damage or deformation exceeding 3.17 mm
1/8 inch from its original dimension, or reduction of SA by 5 dB. This
test shall be performed on all door types, including electromagnet type.
