Cleaning the Test Cell
When the test cylinder has been cooled and removed from the instrument, it should
be cleaned according the following guidelines.
1.
Place the test cylinder in a vice, topside up. The top of the cylinder is
marked on the cylinder wrench flats. Use the wrench flats to clamp the
plugs and cylinder and do not scratch or nick the cylinder or plugs.
The spiral retaining ring found on the bottom plug is used to
retain the seal ring and o-ring during disassembly. In some
cases, it may make removal of the bottom plug more difficult. Its
use is strictly optional and may be omitted if desired.
2.
Remove the cylinder from the vice and replace in the vice top side down.
3.
Unscrew and remove the bottom plug from the test cylinder.
4.
Turn the cylinder over and tap the cement sample out of the test cell with a
hammer. The cylinder is tapered outward from top to bottom so the cement
sample must always be removed through the bottom of the cylinder.
5.
Clean the cement and grease from the top and bottom plugs and cylinder.
6.
When all traces of cement have been removed, grease the inner surfaces of
the test cell, including the seals and o-rings.
7.
Replace the o-rings if they were damaged during the test.
