Corrections - Proceq DIGI-SCHMIDT 2000 ND Mode D'emploi

The curves are valid for horizontal impacts and for the
conversion to a compressive strength in N/mm
ated with concrete cubes 150/150/150 mm. For other
impact directions and sample size and shape, the
respective factors must be considered additionally.

4 .5 .1 Shape Coefficient αs
The PROCEQ standard curves fck7 and fck28 are valid
for sample cubes with a 200 mm side for EPROM
versions up to 1.3 or from a 150 mm side from EPROM
version 2.0. If test specimens with different dimensions
are used for determining the compressive strength in the
pressure testing machine, the shape coefficient in the
first line is to be set or selected in line 2 to 4.
Shape of the test specimen:
1. Line: "variable", see Table 4.1
