Five milliliter (5 ml) of the finished oil shall be added to 45 ml of the synthetic hard water contained in a 100 ml graduated cylinder with an inside diameter of approximately 1.125 in (28.6 mm). The temperature of the liquid shall be adjusted to 77 5F (25 3C). The mixture shall then be stirred
34、 vigorously for 5 minutes by means of an apparatus similar to that shown in Figure 1. The heating bath should be deep enough to cover the 85 ml mark on the graduated cylinder. The stirring mechanism consists of the following: a. Paddle, copper strip, 4.75 in X 0.75 in X 0.062 in (12.1 cm X 1.9 cm X
35、0.16 cm). b. Shaft, stirring, with means to attach paddle, long enough to immerse paddle to approximately 0.25 in (0.64 cm) from the bottom of the graduated cylinder. c.
