45、a.Note: Table 2 conditions are based on PE validation requirements 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. T
46、he intent of multiple conditions is tomaintain equivalent performance 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, howe
47、ver, may be determined by arbitrarily choosing a test pressure 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 9
