We present the results of carrying out multi-object spectroscopy in 10 EIS cluster fields .
Based on the list of 345 galaxy redshifts we identify significant 3D-density enhancements .
For 9 of the EIS clusters we identify significant 3D-concentrations corresponding to the originally detected cluster candidate .
We find redshifts in the range 0.097 \leq z \leq 0.257 which is in good agreement with the matched filter estimate of z _ { \mathrm { MF } } = 0.2 .
We estimate velocity dispersions in the range 219-1160 km/s for the confirmed clusters .
