A limited <br />number of tests were conducted which were designed to verify that the 99 LD -2000 could <br />detect a 3 gal/h leak in the same manner as the original LD 2000 mechanical line leak <br />detector. Testing was performed in accordance with the EPA Pipeline Leak Detection <br />Test Protocols with the exception of the number of tests performed 2 <br />This report is to be used in conjunction with the November 19, 1990 evaluation of the <br />Vaporless LD 2000 mechanical line leak detector.3 Several evaluations have been <br />conducted on various LD 2000 models to determine performance parameters." The <br />original LD 2000 evaluation (November 19, 1990) was conducted on a rigid pipeline that <br />was 176 ft. in length by 3 3/8 inches in diameter with a volume of 81.5 gallons. The <br />results of the testing determined that the LD 2000 had an estimated probability of <br />detection (PD) of 100% with an upper confidence interval of 92 to 100% and an estimated <br />probability of false alarm (PFA) of 0% with a lower confidence limit of 0 to 8% <br />I "Standard Test Procedures for Evaluating Leak Detection Methods: Pressurized <br />Pipeline Leak Detection Systems", EPA/530/UST-90/010, September, 1990. <br />2 The EPA protocol requires that 50 tests be conducted under various conditions <br />for a fall evaluation. This evaluation consisted of 6 tests on a rigid line and 6 tests on a <br />flexible line. <br />3 Performance Evaluation of the Vaporless LD 2000 Line Leak Detector, Final <br />Report, For Vaporless Manufacturing, November 19, 1990, Ken Wilcox Associates, Inc. <br />4 Three previous evaluations were conducted on versions of the LD -2000 for <br />Hourly Testing.
