Have vehicles that are parked within 10 feet moved. If they are going to be moved during the test. Block access so that no travel within 10 feet of the tank is allowed (except for emergencies) (Sec. 8 page 1). Cf1 Prepare tank for testing. Remove tank foot valve and insure tank is isolated from pumping system. Remove any drop tubes if used in tank (Sec. 8 page 1). 62r Stick tank to determine tank bottom to grade, tank top to grade, length of fill pipe, and check for water in tank bottom. Tank should be filled to within 3" of top of fill pipe by client, determine when tank was filled to see if sufficient time has elapsed (min. 6 hours) for product stabilization. Fill out tank testing form using measurements observed. 12 Collect sample of product, measure sample specific gravity and temperatures, set aside 200 milliliters for calibration. Insert temperature probe to correct depth. 6� Bring product to top of fill pipe using table in section 14 page 4 of the Homer instruction manual. Check for gross leaks (assumed if level will not stabilize after adding the amount of product listed in table (Sec. 14 page 4). Er If there are no gross leaks, calculate proper product height (height to produce a minimum of 2.4 psi, maximum of 5 psi at tank bottom) and connect standpipe assembly to fill pipe. Gr Set up equipment. Estimate the amount of product required to reach test level and fill upper reservoir on stand pipe again, check for gross leaks (Sec. 9 page 1). i� If no gross leaks, maintain level in standpipe upper reservoir. &3"' Bleed all vapor areas such as tank lines or manways, if they are present on the tank. Q When tank level is stable in the upper reservoir of the constant pressure stand pipe (CPS), lower pressure .4 PSI and maintain constant pressure on tank. Start 3 hour minimum stabilization time. G9 Calculate exact total tank capacity through including product, return and vent lines (Sec. 4 page 3). Calculate coefficient of expansion (COE). rhi Assemble and set up tank testing equipment. Connect temperature probe to digital indicator, assemble chart recorder and calibrate. Set up bubbler to correct c in the (CPS) (Sec. 9 page 1).
