A method for fine-classification of stars is applied to a sample of about 100 stars within the approximate spectral type range B6-A5. Experiments have been performed to find a method for fine-classification of A stars, both normal and chemically peculiar, within the MK system. It is found that, independent of the definition of the degree of peculiarity, no sharp border exists separating the CP stars from the normal ones. It is also shown that spectral classification can, on average, be performed with almost the same accuracy for CP stars as for the normal ones if cases of extreme peculiarity are avoided.
