841:
between 0.845 and 0.905.
Viscosity 911—
Perform the test at 40.0 ± 0.1
using a suitable capillary viscometer: the kinematic viscosity is between 34.5 and 150.0 mm2·s-1.

Acidity—
Add 20 mL of boiling water to 10 mL of Mineral Oil, Rectal, and shake vigorously for about 1 minute. Allow to cool, and draw off the separated water. To 10 mL of the filtrated aqueous layer add 0.1 mL of phenolphthalein TS: the solution does not produce a pink color. Not more than 1.0 mL of 0.01 N sodium hydroxide is required to change the color to pink.
