- Take a sample of the plastic material weighing, in grams, 100 times its specific gravity (or density) after molding or forming.
- Work this sample on a paper until there is no tendency for the material to pack or cake.
- With the apparatus assembled, close the small end of the funnel with the hand or with a suitable flat strip and pour the sample lightly into the funnel, avoiding any tendency to pack it.
- Then quickly open the bottom of the funnel and start the stopwatch or timer at the same instant.
- Allow the material to run from the funnel as freely as it will, and stop the watch or timer at the instant the last of it leaves the funnel.
