As a continuation of a long-term observational program with the purpose of deriving the chemical abundances of southern planetary nebulae (PN), we present here the line fluxes, colour excesses, electron temperatures and densities, and abundances of He, O, N, S, Ar and Ne for 15 PN. These objects were classified according to the Peimbert classification scheme, taking into account the chemical and kinematical properties as well as distance-independent correlations.
Key words: planetary nebulae: general / ISM: abundances
