Section 2.3 Panel Components
A. Air sealing grommet shall be installed in the interior of a factory placed cutout
located in the following position in the panel
a. 4.075” from the left edge of the panel
b. 7.375” from the top and bottom edge of the panel
B. The cutout in the panel shall measure 6.75”x9.25” and shall be a punched
penetration, saw cutting is not acceptable
C. The cutout location shall allow the air sealing grommet to be located in such a way
that regardless of rack position or overall dimensions, that the unit will be position
beneath the rack allowing for cable penetrations to enter the rack footprint.
D. The air sealing grommets shall meet the following performance criteria for air
leakage at 0.05” inches of H20 static pressure.
a. Less than or equal to 0.07 CFM with no penetrating cables, but without
cover/lid
b. Less than or equal to 4.2 CFM with a single bundle of 32 data cables
installed in the horizontal centerline of the air sealing grommet
c. Less than or equal to 1.1 CFM with a single power cable measuring 9/16” in
diameter installed in the center of the grommet.
d. Less than or equal to 3.1 CFM with four power cables measuring 9/16” in
diameter installed in the horizontal centerline of the air sealing grommet
E. The air sealing portion shall consist of a thermoplastic elastomer (TPE) formed
into a crenellated form, and bounded to the frame of the air sealing grommet
a. The TPE material shall have a tensile strength of 290 PSI per ASTM D412
b. Shall have a tear strength of 100 lbf/in per ASTM D624
c. Shall be flame rated per HB UL94
F. For perimeter cutout locations, the air sealing grommet shall be installed on the
edge of a factory placed cutout located in the following position in the panel
a. The flange shall align with the left edge of the panel
b. 7.75” from the top edge and bottom edge of the panel
G. The cutout in the panel shall measure 7.875”x9.25” and shall be a punched
penetration, saw cutting is not acceptable
H. The air sealing grommets shall meet the following performance criteria for air
leakage at 0.05” inches of H20 static pressure.
a. Less than or equal to 0.07 CFM with no penetrating cables, but without
cover/lid
b. Less than or equal to 4.2 CFM with a single bundle of 32 data cables
installed in the horizontal centerline of the air sealing grommet
c. Less than or equal to 1.1 CFM with a single power cable measuring 9/16” in
diameter installed in the center of the grommet.
d. Less than or equal to 3.1 CFM with four power cables measuring 9/16” in
diameter installed in the horizontal centerline of the air sealing grommet
I. The air sealing portion shall consist of a thermoplastic elastomer formed into a
crenellated form, and bounded to the frame of the air sealing grommet
a. The TPE material shall have a tensile strength of 290 PSI per ASTM D412
b. Shall have a tear strength of 100 lbf/in per ASTM D624
c. Shall be flame rated per HB UL94
