Description of Package and Test Preparation A BU-7 package used for the drop tests was fabricated using component drums purchased from Rheem Manufacturing Company with the following features:
Uniform Freight Classification - Rule 40 55-gallon steel e
outer drum Uniform Freight Classification - Rule 40 16-gallon steel o
inner drum 16 gauge steel cover with one corrugation near the e
periphery (meeting DOT 17H specification) e 12 gauge bolt ring,. 5/8" bolt closure (meeting DOT 17H specification) o Two 5-gallon, 24 gauge steel pails Lead shot in burlap bags was used to simulate actual package contents.
Each 5-gallon pail weighed 35 kilograms (77 pounds) when loaded with the lead shot.
Covers with bolt ring closures were applied to the 5-gallon pails and closures were sealed.
The two pails were put into the inner containers of the BU-7 type container, rubber gasket applied, and 3/16" cover secured in place using 12 5/16" bolts with washers.
Then the phenolic ring insulation was put into place and a gasketed 16 gauge steel cover (with one corrugation near the periphery) was affixed and secured witn 12 gauge bolt ring with 5/8" bolt and lock out.
The container's gross weight was 146 kilograms (320 pounds).
The container was marked "BU-7 TEST" and " EMPTY + TEST WTS."
The container was then subjected to the tests as described below.
7 Free Drop, 4 Feet onto Concrete Pad - Package #1 i
Package #1 was dropped from a fork lift for a height of about 4 feet 8 inches, onto a concrete pad 8 feet by 8 feet square by 8 inches thick.
Impact was at any angle essentially directly on the lugs of the bolt ring, as'shown in the following sketch.
The lock ring was deformed about 1/2" toward the center and about 1/2" from the top toward the bottom.- The cover and drum were correspondingly deformed.
No material leaked from the outer 15G21 8004220 7 %

No seams were broken; no insulation was exposed; no cracks, gashes or gaps devel'oped; and no insulation was exposed.
The cover and lock ring remained in place.

30 Foot Free' Drop onto Concrete Pad - Bottom Drop, Package #5 l*
A new package, Package #5, was then dropped 30-feet onto the 0 from same concrete pad.
The package impacted at about 30 horizontal, with the bottom striking the concrete as shown in the sketch below.
This resulted in partial flattening of the bottom of the container which struck the pr.d.
The bottom edge was pushed in about 2 inches from the rim the center.
The side was dented to a height of about 3 1/2" and a depth of about 2" from the chime.
The bottom buckled outward about 1/2" at the point of its extreme distortion.
No cracks, gashes or gaps developed and no insulation was exposed.
The cover and bolt ring-remained in place.

40-inch Drop Pgnetration Test - Package #5 j
The package which had been dropped 30 feet with its bottom facing down (#5) was then dropped vertically onto a 6" diameter, i
10" long steel bar mounted on the 8-foot by 8-foot square by 8" thick concrete pad.
The package impacted the steel bar on the side of the bottom opposite to that which had been impacted by the previous 30-foot drop, with the edge of the steel bar about one inch in toward the center from the edge.
A small crescent dent in the bottom resulted, about 8" long and 3/4" deep at the maximum point.
No cracks, gashes or gaps developed, and no insulation was exposed.
The cover and bolt ring remained in pldce.
5.
30-foot Drop onto Concrete Pad - Top Drop, Package #4 I
A second 30-foot drop test was conducted on a new package (#4) to determine the damage which would occur in the vicinity of the 16 gauge steel cover (with one corrugation near the periphery) and its bolt ring.
In this 30-foot drop, the container feel with its top bolt ring striking the concrete pad at a 450 angle.
(See below sketch.)
At the point of impact at the top of the outer container, the top was deformed at the bolt ring a distance of about three inches toward the bottom and about 3 1/2 inchas toward the center of the container.
The cover was bowed out about 1/2 inch at its maximum, and the
=
cover and bolt ring remained in place.
The top of the body was crumpled inward at the point of impact.
However, no cracks, gaps or gashes occurred, and no insulation was exposed.

40-inch Drop Penetration Test - Package #4 The package which had been dropped 30 feet with its top facing down (#4) was then dropped vertically onto a 6-inch diameter, 10-inch long steel bar mounted on the 8-foot by 8-foot square by 8-inch thick concrete pad.
The package impacted the steel bar on the edge of the top opposite to that which had been impacted by the previous 30-foot drop and with the edge of the steel bar about one inch in from the edge of the cover.
A small crescent dent in the top resulted, about 6" long and about 3/8" deep at the maximum point.
No crdcks, gashes, or gaps developed, and no insulation was exposed.
The cover and bolt ring remained in place.

Post-Test Examination The package dropped on its top (14) was removed to an enclosed area and opened to determine the extent of inside damage.
The phenolic insulation ring was cracked and crushed only to a slight degree. It was then intentionally fractured for ease in removal. The 3/16" cover was unbolted and the following measure,
ments were made from the inside edge of the inner containment (16-gallon drum with flange) to the inside edge of the outer container, to determine the maximum extent of insulation deformation due to the distortion of the outer conta'iner.
Four measurements were taken, essentially at right angles to each other, as follows:
3 3/4" at the narrowest place, 4",
4 1/8" and 3 7/8".
No cracking of the phenolic resin insulation occurred.
The insulation was crushed to conform to the inward compression of the outer container body af ter the drop.
The 3/16" cover and its corresponding flange were not observed to be bent from plane.
The two 24-gauge, 5-gallon pails were removed and inspected for damage.
The lock rings held the cover tightly in place and there were no fractures of the metal.
The covers of each pail bowed out about 1/2 inch.' The sides of the top pail were compressed about 2 inches.
The sides of the Ubttom pail were undamaged.
The bottoms of both pails were undamaged.
No gaps, gashes or cracks developed in either pail.
There was no loss of contents from either pail.

- 8. Thermal Test on Insulation A test of the effect of flame on the phenolic foam insulation of AEC SP9 specification, which is that used in the construction of the BU-7 package was conducted at the Oak Ridge National Laboratory by C. E. Daugherty and others in 1977.
Samgles of this phenolic foam were subjected to a temperature of 760 C for 10 minutes, in a preheated furnace which was subject to air in the flame environment.
The tests results were that the material retained its shape and its insulating properties, showing only slight signs of crumbling at the edges of the shaped material, t
These results are documented in a report, K/TL 729, " Evaluation of Materials Used in Fire-Resistant Phenolic Foam", March 1, 1978; C.
