11. A mechanical line leak detector <br /> ( )was <br /> ( ) was not <br /> present in the majority of the pipeline systems used in the evaluation. <br /> 12. Please specify how much time elapsed between the delivery of product and the start of the data <br /> collection: <br /> (X) 0 to 6 h (time after completion of circulation and start of test) <br /> () 6to 12h <br /> () 12to24h <br /> () 24 h or more <br /> Temperature Conditions <br /> This system was evaluated under the range of temperature conditions specified in Table 1. The <br /> difference between the temperature of the product circulated through the pipeline for 1 h or more and <br /> the average temperature of the backfill and soil between 2 and 12 in. from the pipeline is summarized <br /> in Table 1. If Option 1, 2 or 5 was used, a more detailed summary of the product temperature <br /> conditions generated for the evaluation is presented in Attachment 4. If Option 3 or 4 was used, no <br /> artificial temperature conditions were generated. <br /> Table 1.SummM of Temperature Conditions Used in the Evaluation Does not include"a ped va or or flexline tests. <br /> Minimum Number of Range of Temperature <br /> Conditions Required Number of Conditions Used* Differences,T de F)** <br /> 1 2 T<-25 <br /> 4 8 -25 <T<-15 <br /> 5 10 -15<T<-5 <br /> 5 13 -5 <T<+5 <br /> 5 13 +5 <T<+15 <br /> 4 8 +15<T<+25 <br /> 1 2 T>25 <br /> *This column should be filled out only if Option 1,2,or 5 was used. <br /> **T is the difference between the temperature of the product dispensed through the pipeline for over an hour prior to the <br /> conduct of a test and the average temperature of the backfill and soil surrounding the pipe. <br /> Data Used to Make Performance Estimates <br /> 13. The induced leak rate and the test results used to estimate the performance of this system are <br /> summarized in Attachment 5. Were any test runs removed from the data set? <br /> (X)no <br /> ( )yes <br /> If yes, please specify the reason and include with Attachment 5.
