[The determination of the Enslin number]

An apparatus after Ezersky was used for the determination of the Enslin number, thereby some error possibilities mentioned in the literature were investigated and compared with the method after the 2. AB-DDR. The dependence of the Enslin number on the height of the powder bed was proofed also at little layer thickness of some substances. The error possibilities are: tending of the powder bed by burning of the lower wet part, occurring of air bubbles below the powder bed and also the capillary action directed against the incorporation at the tip of a completely filled graduated pipet. The apparatus after the 2. AB-DDR as the apparatus after Ezersky, especially with graduated pipet without tip, produced measuring values with little deviation. The latter apparatus allowes a more rational using.
