Test procedure recommended and used is a vacuum slowly <br />applied to establish a stable vacuum of 6" to 10" inches Hg. for one hour using a <br />Standard Industry Vacuum Gauge with a range of -0" to -30" measured in Hg./inches of <br />mercury. The test is completed at the end of one hour/Tanks with a Volume of 20,000 <br />Gallons or less, and 2 hours for Tanks that exceed a Volume of 20,000 Gallons, if the <br />vacuum reading does not decrease below the established vacuum or the Threshold <br />Criteria recommended by the Tank Manufacture, Industry Standard, or Professional <br />Engineer. <br />Product Piping Containment/Vent Piping Containment/Vapor Recovery Piping <br />Containment — The Service Technician will test and certify using methods developed <br />and recommended by the Piping Manufacture, Bravo System UDC Manufacture, Industry <br />Standard or Professional Engineer. Test procedure recommended and used is, Nitrogen <br />Gas pressure, slowly applied to establish a stable pressure of 5 psi for one hour or 3 Psi <br />for 1 hour using a Standard Industry Pressure Gauge with a range of 0 to 15 measured in <br />Psi/Pounds per square inch. If the Product Piping is Fiberglass and the UDC's are a <br />Bravo System Manufacture, constructed of Coated Steel, with an O Ring Seal at <br />Primary/Secondary Product Piping Interface at end of Product Piping Run at UDC's then, <br />Bravo System Manufacture recommends a maximum applied test pressure of 3 Psi. The <br />test is completed at the end of one hour if the pressure reading does not decrease below <br />the established pressure or the Threshold Criteria recommended by the Piping <br />Manufacture, Bravo System UDC Manufacture, Industry Standard or Professional <br />Engineer. <br />Turbine/Product Piping Sump/Fill Riser Sump/Remote Fill Sump/Transition/Vent <br />Sump/Spill Container/Misc. Sump connected to UST System — The Service <br />Technician will test and certify using methods developed and recommended by the Sump <br />Manufacture, Industry Standard or Professional Engineer. The test procedure <br />recommended and used is Hydrostatic with a level change indicator that has been <br />developed to indicate a standard leak rate of 1/4 inch in 24 hours within 30 minutes, and <br />
