Type A Package Testing Results for Model 3451
Water Spray Test: Subject the package to a water spray simulating rainfall
of approximately 2 inches per hour for 1 continuous
hour.
Results: Engineering evaluation – Water exposure of the
magnitude required by the regulations would not affect
the shielding or containment integrity of the package.
Vibration Test: The package was vibrated with a displacement of 0.1"
at approximately 12 Hz for a period of 24 continuous
hours.
Results: No physical damage to the package was observed.
Free Drop Test: The package was dropped from a height of 4 feet onto a
non-yielding surface from a position to cause
maximum damage to the package.
Results: The case was scratched due to the abrasiveness of the
concrete, but no other physical damage to the package
was observed.
Penetration: The package was placed on a non-yielding surface. A
1-1/4-inch diameter, 13-pound steel cylinder with a
hemispherical end was dropped in the vertical position
from a height of 40 inches onto the package to a point
to cause maximum damage to the package.
Results: No physical damage to the package was observed.
Compression: Package was placed on a non-yielding surface and
subjected to a compressive load of at least 13
kilopascals multiplied by the vertically projected area
of the package, in square feet, for 24 continuous hours.
Results: No physical damage to the package was observed.
Weight of package as tested: 96 pounds
Date test completed: July 1996
