Title 46 - Shipping
(a) This section contains requirements for test rigs used in approval testing of separators. A diagram of a typical test rig is shown in Figure 162.050–17(a). (b) Each mixture pump on a test rig must— (1) Be a centrifugal pump capable of operating at one thousand (1,000) revolutions per minute or more; (2) Have a delivery capacity of at least one and one half (1.5) times the maximum throughput at which the separator being tested is designed to operate; (3) Have a maximum delivery pressure that is equal to or greater than the maximum influent pressure at which the separator is designed to operate; and (4) Have either bypass piping to its suction side or a throttle valve or orifice on its discharge side. (c) The inlet piping of the test rig must be sized so that— (1) Influent water flows at a Reynolds Number of at least ten thousand; (2) The influent flow rate is between one and three meters per second; and (3) Its length is at least twenty (20) times its inside diameter. (d) Each sample point on a test rig must meet the design requirements described in Figure 162.050–17(e) and must be in a vertical portion of the test rig piping.
