,. ' Three Testing Methods S One of the primary tests of PVC is The design philosophy behind its quick burst strength. For pipe the 2000PV joint restraint is that meeting the requirements of AWWA the pipe with the restraint should C900, AWWA C905 and ASTM be capable of being tested to the 2241, the minimum quick burst same minimum requirements requirement for the hoop stress is of the pipe alone. In doing so, 6,400 PSI. For DR18, pipe pressure the restraint is shown to have is 755 PSI. no detrimental effect on the 1 £` pipe and will have the same ,' The second test is sustained pressure rating and safety factor - pressure test at a hoop stress of as the pipe on which it is used. 4,200 PSI. For DR18 pipe, that To that end the 2000PV has ,,, rt pressure is 500 PSI. been subjected to hundreds of static and cyclic pressure tests ;;: Third, a conservative cyclic pressure to demonstrate the performance surge design for the pipe exists in and reliability of the restraint. the form of Vinson Equation. , ., n, The 2000PV restraint has been tested to over one million cycles to o f the peak pressures predicted by the ' Vinson Equation for that number of s cycles. ° c 1 wr9 y :, Y "t c F es ., .. .,s. ., � s r h < , *` .a ,�: t "'",fa€ r ' s t a a s sy zaa as S x7 3, a,, �. � r . n s� & �„-� #� S a y � +� � ,s<s, B �, t O n Apr� 1 997 EBAA IroT erto�rmed ; remarkable fo rce de rnons tr a ti n , # of their S eries 2 00 0 PV j oint r i nt With the use-o � EBAA's� Series 2 000PV using.standard mechanical �joint installation on 1 pipe, and a 80 Ton Motor Crane, EBAA Iron lifted a D7 Caterpillar Track Type Tractor weighing in:at 50,350 lbs.
