The objective of this project was to perform burst and cyclic testing on an aged Niedner RIFTS conduit from Fort Lee, and then compare these results with the unaged baseline results from Niedner RIFTS testing performed by SwRI in 2006. Burst testing is used to establish the working pressure of the aged conduit, while cyclic testing is used to represent repeated deployment and retrieval in the field, and determine effects it will have on the burst and working pressure of the hose. Eight 15-foot specimens were extracted from a 500-foot reel of aged Niedner RIFTS conduit for burst testing and cyclic testing. When compared to the previous results, the aged Niedner conduit has a working pressure 100 psig less than that of the unaged baseline conduit. It was also noted that the cyclic testing had less effect on the burst pressure of the aged conduit than the unaged baseline conduit.
