3 TEST PROCEDURE (continued)
3.2 TEST PROCEDURE
1 Place the cup into the stand and level the
cup using the glass plate and bubble level
supplied with the stand (Figure 1).
2 Allow the temperature of the cup and the
sample to stabilise at the agreed
temperature. Check the temperature of the
sample before filling .
3 Place a finger over the cup orifice to close
the orifice (Figure 2).
4 Pour the liquid gently into the cup,
avoiding the formation of air bubbles
(Figure 2).
5 Slide the glass plate over the rim of the
cup to remove excess sample. Avoid the
formation of air bubbles between the glass
plate and the liquid (Figure 3).
6 Remove your finger from cup orifice and
wait for a few minutes to allow any air
bubbles to rise to the top of the liquid.
7 Remove the glass plate and start the
stopwatch (Figure 4).
8 Watch the flow of liquid from the orifice and
stop the stopwatch the moment the flow
breaks for the very first time (Figure 5).
9 Repeat the test.
10 If the test results do not differ by more than
5%, calculate the average of the two test
results and record the result.
