Spectroscopic verification of suspected planetary nebulae. IV.

Verification of 7 objects as PNe (Table 1/A) as well as misclassification o f 5 objects as PNe (Table 1/C) are discussed according to our CCD spectra; the status of 4 objects (Table 1/B) remains uncertain. In Table 2 we give t he estimates of line-strengths and the measured intensities of emission lin es as well as the derived hel. radial velocities and their standard deviati ons.
