Running a Steady State Flow Test
Operation
Prepare to Run a Test
1. Install your specimen in the triaxial cell.
For the details on doing this step, see the installation section of your triaxial
cell manual.
If pore pressure becomes higher than confining pressure — even for a
second — your specimen will be damaged.
Always keep confining pressure higher than pore pressure.
2. If your Triaxial Cell has an upper pore pressure shut off valve, make sure it’s
open.
3. Apply a confining pressure to the specimen.
Confining pressure must always be higher than the pore pressure.
For the details on doing this step, see the operation section of your confining
pressure intensifier manual.
4. Pressurize the pore fluid to the desired starting pressure.
On the RSC, turn the Manual Control control slowly until you reach the
desired pore pressure.
5. If the rest of your system is ready, start your data acquisition procedure.
