If the <br /> line pressure rose to full pump pressure (usually 28 to 30 psi) a non-lealdng line <br /> was indicated. <br /> 8) Since the test times were very short, the testing sequence was repeated at least <br /> three times for each circulation period by repressurizing the line (without <br /> additional circulation) and repeating steps 5 through 7. <br /> Only four types of results were possible.- First, a leaking line is found to be 1 (a <br /> correct conclusion). Second, a non-leaking line is found to be tight (a correction conclusion). <br /> Third, a leaking line is found to be tight (a missed detection) and fourth, a tight line is reported <br /> to be leaking(a false alarm). The results of each test were recorded and compared to the correct <br /> conclusion. <br /> Test Results Summary <br /> The results of the testing have been reported using the Performance Evaluation forms <br /> provided in the EPA protocol which certify the test results. These have been reproduced in <br /> Appendix A. The data,test conditions, and other technical information is summarized in several <br /> attachments to the Performance Evaluation, which are provided in Appendix B. Table I. <br /> summarizes the test requirements for various temperature conditions. Table 2 summarizes the <br /> testing which was conducted for the evaluation arranged from lowest temperature to highest, An <br /> effort—was made to maintain the flow at 3.0 gal/hr for each test run, but due to the difficulty in <br /> maintaining uniform flow through an orifice under operating conditions, some of the rates vary <br /> slightly. <br /> A total of 55 tests were conducted using the EPA evaluation protocol. These were <br /> divided into 26 leak tests, 25 no-leak tests, and 3 vapor tests. No valid failures were recorded <br /> during the evaluation. The leaks tabulated were detected and no false alarms occurred with the <br /> "zero leaks". Since the time period for data collection is very short for the STP-MLD (less than <br /> 5 minutes were required) up to three tests could be conducted for each temperature condition as <br /> discussed in Section 5.2 of the protocol. <br /> 3 <br /> TOTAL P.09 ____ <br />
