6.6 Watch or Stopwatch—A stopwatch
would only be required for high infiltration
rates.
6.7 Level—A carpenter’s level or bull’s-
eye (round) level.
6.8 Thermometer—With accuracy of 0.5
o
C and capable of measuring ground
temperature and water temperature.
6.9 Rubber Hammer (mallet).
6.10 A digital pocket pH Pen-type meter.
6.11 Recording Materials—Record books
and graph paper, or special forms with graph section (See Pages 18 and 19).
7. Calibration
7.1 Rings:
7.1.1 Inspect the Turf-Tec Infiltration rings: determine the area of each ring and the
annular space between rings before initial use and before reuse after anything
has occurred, including repairs, which may affect the test results significantly.
7.1.2 Determine the area using a measuring technique that will provide an overall
accuracy of 1%.
7.1.3 The area of the annular space between rings is equal to the internal area of the
300 mm (12 in.), ring minus the external area of the 150 mm (6 in.) ring. These
areas are included in the attached Excel spreadsheets.
7.2 Liquid Containers—For each graduated Mariotte tube, establish the relationship
between the change in elevation of liquid (fluid) level and change in volume of fluid.
This relationship shall have an overall accuracy of 1%. (See Fig. 2 and Figure 4)
8. Procedure
8.1 Test Site:
8.1.1 Establish the soil strata to be tested from the soil profile determined by the
classification of soil samples from an adjacent auger hole.
NOTE 4—For the test results to be valid for soils below the test zone, the soil directly
below the test zone must have equal or greater flow rates than the test zone.
