frame is rigidly and continuously supported from the bottom. A load of
2kPa 40 psf shall be applied uniformly over the entire surface of the door
for at least 10 minutes. The door will not be considered acceptable if
this load causes breakage, failure, or permanent deformation which varies
the clearance between door leaf and stops to vary more than 2 mm 1/16 inch
from the original dimension.
2.13.2
Door Sag Test
The door and its frame shall be installed normally and opened 90 degrees.
Two 23 kg 50 pound weights, one on each side of the door, shall be
suspended from the door within 125 mm 5 inches of the outer edge for at
least 10 minutes. The door will not be considered acceptable if this test
causes breakage, failure, or permanent deformation which varies the
clearance between the door leaf and floor frame more than 2 mm 1/16 inch
from its original dimension.
2.13.3
Swinging Door Closure Test
Door shall be operated 5000 complete open-close cycles. The door will not
be acceptable if the closure test causes any breakage, failure, or
permanent deformation that causes the clearance between door and frame to
vary more than 2 mm 1/16 inch from the original dimension.

EXECUTION
3.1
INSTALLATION
3.1.1
Installation Supervision
Furnish the services of a qualified installation engineer or technician
regularly employed by the shielding manufacturer/fabricator for a minimum
of three 8 hours working days to instruct Contractor personnel in the
installation of the RFI shield. A qualified installation technician is
acceptable in lieu of a qualified installation engineer. After the
shielded enclosure has been completely installed including RF filters,
vents, and exhaust fans, furnish the services of the engineer or technician
described herein to inspect the installation for compliance with the
specifications. The inspection shall be made before any finishes or the
concrete topping coat are installed.
3.1.2
Panel Installation
Lay panels in a straight line with true, level, and even surfaces and with
the joints in alignment; install them in accordance with the shielding
manufacturer's recommendations. Exercise care while handling and
installing metal shielding panels to ensure that panels are not damaged.
Clean exposed surfaces of all dirt, finger marks, and foreign matter
resulting from manufacturing processes, handling, or installation. Inside
the enclosure, mount items including boxes, conduits, fixtures, and
switches directly to the RF panels with 16 mm 5/8 inch long, zinc-plated,
self-tapping screws. Keep electrical conduits as close to RF shielding as
possible. Do not use framing-joining system bolts to mount material and
equipment. If material and equipment penetrate shielded enclosure, seam
weld or solder materials and equipment to both shielding surfaces.
3.1.3
Surface Preparation
Clean and buff surfaces to ensure good electrical contact with shielding
