21C Fiber Drum Rail Impact Test
Abstract
The U.S. Army Defense Ammunition Center and School (USADACS), Validation Engineering Division (SMCAC-DEV), was tasked by USADACS, Transportation Engineering Division (SMCAC-DET), to test a loading and bracing procedure for nitroguanidine packed in 15.5 -diameter by 24.4 -high Department of Transportation (DOT) 21C fiber drums in a 50'-6 -long boxcar. Inert test samples of the DOT 21C drums were fabricated and loaded into the boxcar. The boxcar was then tested IAW TP-91-01, Transportability Testing Procedures, July 1991, for rail impacts at 4, 6, and 8.1 miles per hour (mph) in the forward direction and 8.1 mph in the reverse direction. The load was inspected after each impact for movement and damage to the cargo. Lid undercutting and drum compaction were observed at all impact speeds. Drum failure occurred at 8.77 mph. After impacting, the test load was removed from the boxcar and inspected for damage. It was noted by the observers that the drum samples had a soft fill. The real product has a hard fill which adds to the load's ability to eliminate or reduce the amount of compaction. As a result of testing, the load design failed due to incorrect sample preparation. The test samples will be rebuilt and retested, if requirement for approval still exists.
