Tracer Research Corporation <br /> i <br /> Nonvolumetric TTT Method _Tracer Tight (TM) <br /> Version <br /> Test Conditions During Evaluation (continued) <br /> The tests were conducted with the tank varying percent full. <br /> The temperature difference between roduct added to fill the-tank and product already in <br /> the tank ranged from -NIA °F to °F, with a standard deviation of NJA 'F. <br /> The product used in the evaluation was varying gasoline diesel jet fuel and heating oil <br /> This method may be affected by other sources of interference. List these interferences <br /> below and give the ranges of conditions under which the evaluation was done. (Check None <br /> if not applicable.) <br /> [ ] None <br /> Interferences Range of Test Conditions <br /> Limitations on the Results <br /> ` The performance has not been substantially changed. <br /> ` The vendor's instructions for using the method are followed. <br /> ` The tank contains a product identified on the method description form. <br /> ` The tank capacity is _ gallons or smaller. <br /> ` The difference between added and in-tank product temperatures is no greater than + <br /> or - degrees Fahrenheit. <br /> [ j Check if applicable: <br /> Temperature is not a factor because Tracer detection outside of tank does not depend <br /> on fuel temperature inside tank Temperature does not affect he amount of Tracer <br /> released. <br /> ` The waiting time between the end of filling the test tank and the start of the test data <br /> collection is at least _ hours. <br /> ` The waiting time between the end of"topping off' to final testing level and the start of <br /> the test data collection is at least <x hours. <br /> ` The total data collection time for the test is at least _ hours. <br /> ` The product volume in the tank during testing is 0-100 % full. <br /> ` This method [ ] can [ ] cannot be used if the ground-water level is above the bottom <br /> of the tank. <br /> Other limitations specified by the vendor or determined during testing: <br /> 1.
