and the dimensions of the boxes to be placed above/below.
In each rack a number of knock-outs will be knocked
out in the field during the final installation of the
racks.
Requirements to knock-outs:
2.8.1 The knock-out shall be produced in a way, that leaves
no crackings or fractures in the surface, and the knock-out
shall have a good and uniform galvanic contact with
the panel around the perimeter.
2.8.2 The knock-out operation shall be done by simple, general
applied handtools. When properly operated, the knockout
operations shall leave the surface of the remaining
panel around the perimeter of the hole in a unbowed
and smooth condition, suitable for a hermetically sealed
joining with a tube fitting.
Neighbouring knock-outs must not be affected due to
a properly operated knock-out operation.
2.9 R̲A̲C̲K̲ ̲M̲A̲T̲E̲R̲I̲A̲L̲ ̲A̲N̲D̲ ̲F̲I̲N̲I̲S̲H̲
The cabinet and doors are to be fabricated from steel,
16-gauge or thicker. Exterior, nongasket surfaces are
to be primed, phosphate treated, or otherwise treated
prior to painting. Vendor's painting practice is acceptable
if the colour specified by CR can be matched. Interior
surfaces need not to be painted, but shall be treated
to be rust resistant, except for internal gasket areas.
Gasket surfaces, interior and exterior, are to be finished
with a plating, dipping, or bonding process compatible
with both the type of gasket used and the severity
of wear the surfaces will encounter. The following
finishes are acceptable: Tin, cadmium or zinc plating,
or galvanizing.
2.10 T̲Y̲P̲E̲ ̲O̲F̲ ̲G̲A̲S̲K̲E̲T̲ ̲M̲A̲T̲E̲R̲I̲A̲L̲ ̲U̲S̲E̲D̲
The gasket material used must be reasonably close in
electrochemical activity to the gasket surface material.
It must be stiff and sharp enough to penetrate surface
oxides if the gasket cannot tolerate scrubbing or wiping,
and must be highly resilient to avoid compression-set
effects.
The new design (available 1st July 1981) of Instrument
Specialities No. 97 - 500 beryllium copper finger stock
gasket plated with tin or equivalent is acceptable.
2.11 P̲E̲R̲M̲A̲N̲E̲N̲T̲ ̲S̲E̲A̲M̲ ̲C̲L̲O̲S̲U̲R̲E̲
All structural seams which are permanently closed must
be continously seam welded. Spot welding before seam
welding is encouraged to reduce warpage and to help
prevent seam cracking during load deflection. Only
those seams which form part of the contigous shielding
surfaces need be seam welded. Certain seams inherent
in compression stop or gasket channel structures may
not have to be seam welded. If a choice is to be made
whether to permanently close a seam or to gasket a
seam, a welded seam is preferred.
2.12 S̲E̲M̲I̲-̲P̲E̲R̲M̲A̲N̲E̲N̲T̲ ̲S̲E̲A̲M̲ ̲C̲L̲O̲S̲U̲R̲E̲
The joining of 2 racks by the joiner frame forms a
semi-permanent seam closure.
Finger stock gasket, the new design of Instrument Specialties
No. 97 - 500 beryllium copper gasket, or equivalent,
used in conjunction with appropriate compression stop
around the joining perimeter is acceptable. The two
racks are bolted together with bolts placed around
the perimeter with a spacing sufficient to ensure optimum
gasket compression (see 2.13).
2.13 D̲O̲O̲R̲ ̲S̲E̲A̲M̲ ̲C̲L̲O̲S̲U̲R̲E̲
Finger stock gasket, the new design of Instrument Specialities
No. 97 - 100 beryllium copper finger stock plated with
tin is used on the door. The gasket is mounted in a
0.6" recess to provide a positive compression stop
all around the door.
The compression stop surface is treated like a gasket
surface in order to make an extra contact between the
rack and door.
The recess for the gasket strip is placed to provide
a protection of the gasket to damage due to handling
(door off and on, etc.).
2.13.1 The finger stock gasket has a free height greater than
0.218".
Maximum gap between door and cabinet surfaces is 0.156
inches (including anticipated wear effects due to 5
years of normal operation) thus providing a min. compression
of the gasket to 72 per cent and a max. compression
to 27 per cent (0.06 inches gap). Within these limits
the shielding will be excellent.
2.13.2 The gaskets shall stay in adjustment in the recessed
frame.
2.13.3 The gasket shall be field replaceable
2.14 D̲O̲O̲R̲ ̲H̲I̲N̲G̲E̲ ̲A̲N̲D̲ ̲L̲A̲T̲C̲H̲ ̲M̲E̲C̲H̲A̲N̲I̲S̲M̲
The door hinge and latch assembly shall be aesthetically
attractive and easy to operate. They shall be able
to provide sufficient force and travel to compress
the gasket.
Four latch points and four hinge points shall be feasibly
placed on each door.
The door handle shall be a single flush "T" - handle
for full-hand operation with one hand (all fingers).
2.14.1 The max. torque to operate the latch shall be 15 in
lbs.
2.14.2 After final adjustment at factory of hinges and latch
mechanisms, the adjustment shall be locked by a pin
or by using an equivalent method to freeze the adjustment
during the lifetime of the racks.
It is mandatory that doors are easily removable in
the field without the need for readjustment or realignment
when they are reinstalled.
2.14.3 Opening and closing of the door shall be a smooth operation.
Binding scrapping or hang-up must not occur during
opening and closing of the door.
2.15 V̲E̲N̲T̲I̲L̲A̲T̲I̲O̲N̲
See drawing 30-940, sheet 4.
Air for cooling of equipment in the racks enters through
2 perforated areas in the door and leaves the rack
through a perforated area in the top panel.
2.15.1 Each perforated area in the door is approx. 15 inches
in width and 10 inches in height, covering an area
of not less than 150 square inches each.
The panel mounting channels covers 36 units of 1.75
inches each, numbered from bottom to top.
The lower perforated area shall be placed in front
of the units 3-8.
The upper perforated area shall be placed in fron of
the units 22 - 27.
2.15.2 The perforated area in the top panel shall not be less
than 400 square inches. 30-940, sheet 4 shows the constraints
on placing the perforated area due to knock-outs and
the boxes placed by the knock-outs.
2.15.3 The hole pattern of the perforated areas shall use
3/16 inch holes to give a 50 per cent open area. 2
pieces of 16 guage (0.06 inches) perforated steel plates
shall be welded on the inside, back to back.
2.15.4 It may be required (see appendix D of this contract)
in order to improve the electromagnetic shielding effectiveness
of the rack to attach honeycomb with bolts and gaskets
to the inside surface. This risk shall be adequately
foreseen in designing the perforated areas.
2.16 F̲I̲L̲T̲E̲R̲ ̲P̲A̲N̲E̲L̲
A filter panel covers each perforated area in the door
(see 2.15).
These filter panels shall be a decorative element hiding
the perforated areas and they shall provide pre-filtering
of the input air.
The panels are mounted with ball studs or an equivalent
method allowing easy removal. The panels shall be designed
for recoval by hand without use of any tools. They
shall be supproted sufficiently well to prevent saggering
or significient bowing.
The panels shall contain a washable foam filter.
The surface of the panel shall be perforated and the
panel with foam filter installed shall provide low
resistance to air flow.
The corners shall be round rather than square.
The panels shall carry the loco of CR A/S. The colour
of the panels shall be defined by CR.
2.17 T̲O̲U̲C̲H̲-̲U̲P̲ ̲P̲A̲I̲N̲T̲
One paint of touch-up paint shall be delivered per
each 3 racks.
3̲ ̲ ̲P̲A̲C̲K̲I̲N̲G̲ ̲C̲O̲N̲T̲A̲I̲N̲E̲R̲ ̲A̲N̲D̲ ̲P̲A̲C̲K̲I̲N̲G̲
The vendor shall supply a packing container or crate
to protect the individual racks during surface or air
transportation overseas.
The container/crate shall be reuseable at least once.
The container shall be on blocks to allow handling
with a fork lift.
It shall be considered that the containers will be
transported in 20 feet or 40 feet freight containers.
