45、rements per PPI TR-3 with Condition 6 being 85% of Condition 1 test pressure hoop stress and six times greaterminimum average time before failure. Conditions 2 through 5 are linear stress and time interpolations between Conditions 1 and 6. The intent of multiple conditions is tomaintain equivalent p
46、erformance criteria, but provide for retest in the event of ductile failure. The test pressure hoop stress levels for Conditions 2-5 are linear interpolationsfor arbitrarily chosen time increments. An equivalent performance requirement, however, may be determined by arbitrarily choosing a test press
47、ure hoop stress betweenConditions 1 and 6 and linearly interpolating the minimum average time before failure. For example for PE3710 and PE4710 material, at 670 psi test pressure hoop stress,the minimum average time before failure would be 927 hours (200 + (750 670) (1200 200) / (750 640) = 927).BCa
