Test Method
Tests the ability of medium to high viscosity oils to separate from water
when water contamination and turbulence are encountered. The sample is
stirred together with distilled water for 5 min. at constant temperature. After
a specified settling period, the degree of separation is measured by volume
and the percentage of water in oil is determined. For lighter oils and
synthetic fluids, the ASTM D1401 Water Separability Test is used.
Demulsibility Apparatus
. Conforms to the specifications of ASTM D2711
. Variable stirrer speed
. Choice of digital or analog bath models
Stirrer - Complete stirrer assembly per Fig. 1 and 2 of ASTM D2711,
including variable high speed drive motor, stainless steel propeller shaft,
top, center and bottom bearings, and steel motor housing with positioning
plate. Entire assembly mounts vertically in K39190/K39199 Constant
Temperature Bath. Built-in tachometer disc allows for precise stirrer
speed adjustment.
Constant Temperature Baths - Standard model holds two K39103 Stirrers
and two K39120 Separatory Funnels in proper alignment for demulsibility
characteristics testing. Stirrers mount securely on a stainless steel support
plate having brackets for testing and drainage positions. Separate motor speed
controls are provided for each stirrer. All wetted parts are constructed of
stainless steel.
Microprocessor digital temperature control with dual LED displays for
setpoint and actual temperatures and an illuminated bath interior with window
for viewing sample cylinders. Digital LED speed control is provided for each
stirrer.
