Site Testing. Slump Test – always do your slump test before making your cubes to ensure the concrete is usable. If the slump test fails to meet the range limit as dictated by the British Standard (shown in the table below) then the load should be rejected. Place the damp slump cone on a flat, hard surface.

Like STFI edgewise compressive strength, the ring crush test is intended to characterize a paperboard's resistance to crushing by inplane compressive forces. In the foregoing section on STFI edgewise compressive strength, certain shortcomings of the ring crush test were pointed out that make it of questionable value.
are the Ring crush test (RCT) and the STFI Shortspan compression test (SCT). Certain limitations regarding the Ring crush testing method exist, pointing out that this method does not measure the true intrinsic edgewise compressive strength. Preferences were given in literature to the use of the STFI Shortspan compression test.
