• -4- 5.4 Stopwatch Use a stopwatch accurate to within 0.2 seconds. 5.5 Flow Meter Use a flow meter to determine the required pressure setting of the delivery pressure gauge on the nitrogen supply pressure regulator. This pressure shall be set such that the nitrogen flow rate is between 2.0 CFM (120 CFH) and 4.0 CFM (240 CFH). 5.6 Leak Detection Solution Any liquid solution designed to detect vapor leaks may be used to verify the pressure integrity of the test equipment prior to conducting the test. 5.7 Condensate Collection Vessel A container approved for use with gasoline that can hold at least a half gallon of material. 5.8 Graduated Cylinder A graduated cylinder suitable for use with gasoline capable of measuring to the nearest ounce or mL. 6 PRE-TEST PROCEDURES 6.1 The following safety precautions shall be followed: 6.1.1 Only gaseous nitrogen shall be used to pressurize the system. 6.1.2 An 8 oz. pressure relieve valve shall be installed on the Test Port Assembly to prevent the possible over-pressurizing of the Clean Air Separator. 6.1.3 A ground strap should be employed during the introduction of nitrogen into the system. 6.2 There shall be no Phase I bulk product deliveries into or out of the gasoline storage tank(s) within the three (3) hours prior to the test or during the performance of this test procedure. 6.3 All pressure measuring device(s) shall be bench calibrated using a reference standard. Calibration shall be performed at 20, 50, and 80 percent of full scale. Accuracy shall be within two percent at each of these calibration points. Calibrations shall be conducted on a frequency not to exceed 180 days. Calibration documentation shall be maintained with the equipment at all times.
