7. Procedure
7.1 Infiltration Testing:
7.1.1ThisThe hydrostatic infiltration test procedure is applicable where the measured water table is 2 ft (610 mm) or greater
above the pipe barrel at the midpoint lower manhole of the test section (see Note 1). section. Where the ground water elevation
is indeterminate, less than 2 ft (610 mm) above the top of the pipe barrel, or the line is partially below the water table, use a
combination of both the air test and infiltration procedure.
NOTE1—What can be called false infiltration represents condensate on the pipe walls. This may amount to as much as 50 gal/in. diameter·mile·day (4.6
L/mm diameter·kilometre·day). Thus, evaluate flow in the pipeline for this condition.
7.1.2Determine the allowable infiltration rate for the test section using 1—The most practical method for testing isTest Method
C 828, and is recommended. However, where ground water is present and meets the criteria established in 7.1, the infiltration test
procedure outlined in this practice is recommended.
7.2 Determine the allowable infiltration rate for the test section using Table 1.
7.1.3Discontinue all pumping of ground water for a period of 24 h prior to testing.
7.1.4Plug the inlet to the test section to be tested. It is usually necessary to also plug the inlet of the upper manhole to prevent
the manhole from filling with water or provide a method of de-watering the manhole or remotely removing the plug at the inlet
to the test section. Securely plug all lateral inlets to the line.
7.1.5To determine the infiltration rate, measure the flow at the outlet of the test section.
7.1.5.1At the outlet of the test section, collect the water and measure the quantity collected within a specific time. Achieve
collection and measurement with the use of a plug having a pipe outlet and a calibrated container after constant flow is generated
at the pipe outlet.
7.1.5.2An alternate method of measurement is to use a calibrated weir (see Note 2) installed at the outlet of the test section and
directly read the rate of flow.
NOTE2—The apex of weir should be as near to the pipe invert as practical.
7.1.6If the allowable infiltration rate (see 2—What can be called false infiltration represents condensate on the pipe walls.
