5.2.1 Checking the centering of the ram assembly
The proper centering of the ram assembly assures proper and uniform distribution of the
force to the sample during the execution of the compression test.
This check is normally carried out before checking the calibration of the system and
checking the stability of the frame through the force transfer test with the strain gauged
column.
This checking should also be carried out if tests on high strength concrete/explosive
samples are often carried out.
To check the centering of the ram assembly:
1. Remove the lower platen and distance pieces;
2. On the compression frame remove the cover of the ram assembly to expose its fixing
brackets;
Fig. 5-6
3. Use a straight edge and a tape measure to check the centering of the ram assembly in
all directions with respect to the columns of the compression frame;
