Effect of the Measurement Equipment on the Test Results in Impact Testing of Concrete.

It is shown by means of some examples from studies carried out by the author himself and by other researchers how certain properties of electronic measuring devices can affect the shape of the measured curves during impact or dynamic tests. In particular, it is shown how the measurement results can be affected by the upper limiting frequency of the measurement amplifier, the orientation of the pressure sensor during measurements of explosion pressure, and the acceleration of the load transducer.
