5.2.3 Checking the status of distance pieces
To assure proper and uniform distribution of the force to the sample during the execution
of the compression test, status of distance pieces and platens must be periodically
checked.
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.
Checking the status of distance pieces requires:
•
Checking that the surfaces of the distance pieces are not damaged (free of deep dents
and incisions);
•
Checking the planarity of the lower and upper surface;
•
Checking the status of the centering screw;
•
Checking that, once the distance pieces are installed on the machine, they do not tilt
pushing them from the top.
