(3) Fill a cylindrical container, at least 3 inches in diameter, with the sample to a depth
of at least 3 inches.
(4) Bring the sample to 77 ± 1 ºF and level the exposed surface.
(5) Level the penetrometer.
(6) Place the container on the penetrometer table so that the approximate center of the
exposed surface lies beneath the tip of the cone.
(7) Adjust the height of the penetrometer table and plunger assembly until the tip of the
cone just touches the surface of the sample.
(8) Release the plunger assembly and allow to remain free for 5 seconds.
(9) Read the penetrometer [depth of penetration expressed in tenths of millimeter (mm)].
