• -6- <br /> 5.4 <br /> 5.4 Liquid Volume Meter. Use the totalizer on the gasoline dispenser to <br /> measure the volume of gasoline dispensed during the test. <br /> 5.5 Portable Gasoline Tank Assembly. A portable tank, meeting fire safety <br /> requirements for use with gasoline, shall be used to receive the gasoline <br /> dispensed during this test. The tank shall have sufficient volume so that at <br /> least 4.5 gallons may be dispensed prior to activating the primary shutoff <br /> mechanism of the dispensing nozzle. Portable tanks shall have a permanent <br /> label or mark indicating the total fuel capacity in gallons. Tank material, <br /> likely to provide contact with the nozzle spout, or V/L adaptor, during the <br /> entire dispensing event, shall be constructed of aluminum or brass or other <br /> materials approved by the local fire codes for such application. The tank <br /> and required plumbing configuration is shown in Figure 3 and Figure 4. <br /> This configuration permits a portion of the vapors displaced during testing <br /> to be returned to the underground storage tank (UST). The minimum and <br /> maximum dimensions shown in Figure 2 and Figure 4 shall be adhered to in <br /> all cases. <br /> 5.6 Stopwatch. Use a stopwatch accurate to within 0.2 seconds. <br /> 5.7 Lubricant. Appropriate lubricant shall be used to ensure a leak-tight seal <br /> between the 0-ring in the V/L adaptor and the nozzle spout. Motor oil (any <br /> weight) is acceptable for lubricating the 0-ring. Contact Healy Technical <br /> Services with any questions about other lubricants that may be used in <br /> conducting this test. <br /> 5.8 Leak Detection Solution. Any liquid solution designed to detect gaseous <br /> leaks may be used to verify the pressure integrity of test equipment during <br /> this test. <br /> 5.9 Pressure Measuring Device. An electronic pressure measuring device <br /> with a full scale range that shall not exceed 0-10 inches WC with a minimum <br /> accuracy of 0.5 percent of full scale. A 0-20 inches WC device may be used <br /> provided the minimum accuracy is 0.25 percent of full-scale. <br /> Healy Model 900 Nozzle V/L Test Procedure, Exhibit 5—Executive Orders VR-201-D and VR-202-D <br />
