ROLLER AND DROP TESTS OF POTENTIALLY DEFECTIVE RAIL

Roller tests and drop tests were conducted on a batch of rail suspected of having interior defects. A Sperry hand testing device had been used to indicate the defects. A total of 25 rails were subjected to the roller test. A camber of 13/16" on rolls spaced 90 in. apart was used. All 25 rails endured the test with out fracture. Next, the rails were submitted for drop testing. This was carried out with the rail placed on a 48" span with a drop of 22 feet and the blow of the tap was directed at the location marked by the Sperry hand check. Results indicated that interior defects were not present.
