7 TESTING <br /> 7.1 Open the ball valve marked "B" from Figure 2 or Figure 2H. The pressure <br /> measurement device installed on the Test Port Assembly should now be reading <br /> UST and Clean Air Separator ullage pressure (or vacuum). <br /> 7.2 If the station vacuum is greater than (more negative) than -2.00"wc, then proceed <br /> to Section 7.2.1. If less than —2.00" wc, then proceed to Section 7.3: <br /> 7.2.1 Close the ball valves marked "A" and "B" from Figure 2. <br /> 7.2.2 Open the ball valve marked "C from Figure 2 and wait one minute. <br /> 7.2.3 If necessary, use the needle valve on the Test Port Assembly to bleed air into <br /> the bladder until the vacuum level reaches as close to a whole number on the <br /> pressure measurement device as the accuracy of the device will provide (ie. <br /> -2.00, -3.00, -4.00, -5.00, -6.00, -7.00, -8.00). Make sure the needle valve <br /> is closed. Record this vacuum and start the stop watch to begin a 5 minute <br /> decay. <br /> 7.2.4 Record the vacuum at one-minute increments up to 5 minutes. <br /> 7.2.5 Using the information from Table 1, verify that the vacuum after 5 minutes is <br /> equal to or greater than the allowable minimum for the initial vacuum recorded <br /> from Section 7.2.3. <br /> 7.2.6 If the vacuum is greater than the allowable minimum, the Clean Air Separator <br /> passed the test. <br /> 7.2.7 If the vacuum is less than the allowable minimum, the Clean Air Separator <br /> failed the test. <br /> TABLE 1 <br /> Allowable 5 Minute Vacuum Decay for Clean Air Separator _ <br /> Vacuum at Start of Test Allowable Minimum Vacuum after 5 min. <br /> inches we inches we <br /> 8.0 5.5 <br /> 7.0 4.7 <br /> 6.0 3.8 <br /> 5.0 3.0 <br /> 4.0 2.2 <br /> 3.0 1.5 <br /> 2.0 0.8 <br /> Healy Clean Air Separator Test Procedure, Exhibit 4—Executive Orders VR-201-Dand VR-202-D <br />
