The Sobolev exact integration method and high-resolution IUE data are used to examine the properties of the fast winds exhibited by the central stars of the planetary nebulae NGC 6543 and NGC 6826. An attempt is made to evaluate the parameters of the central stars as accurately as possible. The associated mass-loss rates (M-dot) are (4.0 + 10 or - 2.1) x 10 to the -8th and (5.2 + 34 or - 4.5) x 10 to the -8th solar masses/yr for NGC 6543 and NGC 6826, respectively. A comparison with the Population I OB stars in the (log L, log M-dot) diagram shows that the mass-loss phenomenon in these central stars is very likely due to the same mechanism thought to prevail in early-type stars of Population I, i.e., the radiation pressure on heavy ions.
