0 <br /> Vaporless 99 LD-2000 Addendum <br /> 6.0 Test Results and Limitations <br /> The performance parameters for the 99 LD-2000 are summarized in Table 3. <br /> Probability of DetectionR,,) <br /> The 99 LD-2000 was correct in its determination of a leak for all of the leak tests. The estimated <br /> PD of a 3 gal/h leak is 100%with an upper confidence limit of 61 to 100%. <br /> Probability of False Alarm(PFA) <br /> The 99 LD-2000 was correct in its determination of a tight pipeline for all of the fight tests. The <br /> estimated PFA is 0%with a lower confidence limit of 0 to 39%. <br /> Time to Conduct a Test <br /> All of the tests were completed in under one minute with one exception. One of the tests required <br /> 20 minutes to complete due to a temperature differential extreme that was present during the test <br /> (See Table 1). <br /> Maximum Line Size <br /> The EPA protocol allows pipeline leak detection methods to be used on pipelines with up to <br /> twice the volume of that used in the evaluation. If the EPA protocol is used to calculate the <br /> performance parameters, the 99 LD-2000 can be used on rigid pipelines up to 170 gallons and <br /> flexible pipelines up to 39.5 gallons. <br /> Page 7 <br />
