n 3.1. GENERAL 3.1.1. Xerxes tanks are tested prior to shipment, but all tanks must be retested prior to installation — even if shipped with vacuum — in order to verify the absence of shipping and handling damage. 3.1.2. The tester is responsible for verifying that all of the test equipment is in good working condition, and is properly configured and calibrated. 3.1.3. Construct a test manifold as shown in FIGURE 3-1. The air -supply gauge must have a maximum full-scale reading of 15 psig with 114 -Ib. or 1110 -Ib. increments, and a pressure -relief device set at 6 psig [4 psig for 12 -foot tanks]. 19 1011111*15 3.1.4. In air tests, temperature change could be a factor in changes in gauge readings. Note: Multiple test manifolds will be required to test multicompartment tanks. 3.1.5. It is the installer's responsibility to select a thread sealant that is compatible with the product being stored. Some sealants cannot be used with some products. Remove, clean and redope all factory -furnished temporary plugs with appropriate thread sealant. Install permanent plugs in all unused openings. Make sure all manway bolts are tightened, and fitting plugs are properly doped and sealed. 3.1.6. Refer to the appropriate section below for instructions for the following situations: 3.1.6.1. For testing a single-wall tank, see SECTION 3.2. 3.1.6.2. For testing a double-wall tank with a dry interstitial space, see SECTION 3.3. 3.1.6.3. For testing a double-wall tank with a liquid -filled interstitial space, see SECTION 3.4. C 3.1.6.4. For testing a single-wall multicompartment tank with a single bulkhead, see SECTION 3.5. 3.1.6.5. For testing a single-wall multicompartment tank with double bulkhead(s), see SECTION 3.6. 3.1.6.6. For testing a double-wall multicompartment tank with dry interstitial space, see SECTION 3.7. 3.1.6.7. For testing a double-wall multicompartment tank with liquid -filled interstitial space, see SECTION 3.8. 3.1.7. If damage is detected, do not attempt repairs. Contact the UST coordinator at the Xerxes plant nearest you. Telephone and fax numbers are found on the back cover of this manual. 3.1.8. After installation and before backfilling to grade, testing must be repeated to verify that no damage has occurred during installation. When the tank is under pressure, the manways and/or fittings may dislodge, or the tank could rupture and result in death, serious personal injury or property damage. Before beginning the test, notify all people on the test site to remain in a safe location. ALWAYS ATTEND TO THE TANK DURING THE TEST. Shand dear of manways, fittings and tank ends during the test. AWARNING The maximum test pressure is 5 psig [3 psig for a 12 -foot tank]. Position the pressure gauge so that the pressure readings can be dearly read at all times See FIGURE 3-2. I9[tli11V The pressure -relief device or regulated air source must be rated at a maximum of 6 psig [4 psig for a 12 -foot tank] to reduce the risk of overpressurizing the tank.
