13Simultaneous Procedure: testing (cont'd.) •Join all connections of the primary system.An optional pressure test may be performed once this step is completed to assure integrity of the line while connections are visible. Example: •Complete closure of the containment system. Primary is pressurized to 50 psi; •Connect pressure gauges to each portion(primary and containment)of the system.These containment to 30 psi. The differ- gauges should have full-scale readings no greater than two times the test pressure or to the ential of 20 psi is enough to detect higher pressure of either system,whichever is greater. any communication between the .Pressurize the primary system to its intended test pressure and close off the source to two lines.Should pressure change, check for pressure drops.Allow the system to stabilize should temperature changes be either or both systems may need to occurring which can affect the gauge pressure. be inspected and made tight.In this example,pressure increase in the •Pressurize the containment system to a different pressure than that of the primary.Allow secondary indicates a leak in the this system to stabilize also.
