- Benötigte Geräte:
- Blauband-Rundfilter (z.B. Fa Schleicher & Schuell, 5893, aschfrei, Durchmesser 90 mm) Reagenzglas (12 mm Durchmesser) Stoppuhr
- Durchführung:
- Die Dispersion wird im Wasser auf 25 % FG verdünnt. Davon werden 5 ml in den Filter gegossen und die Zeit gestoppt, bis der erste Tropfen durch den Filter durchgeht (=Penetrationszeit). Ferner wird die Menge Dispersion gemessen, die innerhalb von weiteren 5 Minuten (nach dem ersten Tropfen) durch den Filter penetrieren. Die Menge wird angegeben als "mm Füllhöhe".
In der Tabelle werden Penetrationszeit mit Füllhöhe als sec/mm angegeben. Je kürzer die Zeit und größer die Füllhöhe desto besser die Penetration.
