- The chemically peculiar (CP) stars of the upper main sequence are perfect tracers for several astrophysical processes.
Their study especially in open clusters further helps to establish their evolutionary status. The latter is most important to
understand the origin and evolution of the CP phenomenon, i.e. the connection between diffusion and a stellar magnetic
field. There are two important topics, we cover with this paper. First of all, we investigate the reliability of the CCD
a photometry for fainter objects in open clusters. The latter method is able to detect CP stars very efficiently, but
still a spectroscopic verification is needed to verify the photometric candidates. On the other hand, already published
spectral classifications on the basis of photographic plates and prismtechnology have to be tested withmodern instruments.
Classification resolution spectroscopy is presented for thirty five bona-fide CP candidates. Twenty six of them are located
within the boundaries of fourteen open clusters, for which we also investigated their membership probabilities. Apart from
five objects, they seem to be members of the respective clusters. The objects were classified in the framework of a refined
Morgan-Keenan system with the extension of well established CP star spectra. We confirm the CP nature of all but one
target. The results of a photometry and the spectral classifications are in excellent agreement. For the cluster members
we find a continuous sequence of CP stars from 10 to 850Myr, the whole range of investigated cluster ages.
