Use 
Corn oil is used for cooking, also as a salad oil and in the manufacturing of margarine.METHOD 1
Test Equipment 
Instrument: Viscometer or Rheometer
Torque Range: LV
Spindle: YULA-15E
Accessories: Enhanced UL Adapter,
TC-550AP Programmable Bath
Speed: 2, 4, 6, 8 and 10 RPMTest Method
The Enhanced UL Adapter™ may be used with various Brookfield Viscometers or Rheometers. In our example, we used a Brookfield DV3TLV Rheometer with Rheocalc™ software for automated instrument control and data acquisition. Our test temperature of 25°C was maintained by direct immersion of the Enhanced UL Adapter sample chamber into a TC- 550AP Programmable Refrigerated Bath. Representative data from the analyses in Figure 1 show a relatively constant viscosity at 25°C (55 cP to 52 cP) over the speed range tested.

METHOD 2 
Test Equipment 
Instrument: Viscometer or Rheometer
Torque Range: LV
Spindle: LV-1
Accessories: TC-550AP Programmable Bath
Speed: 25, 50, 75 and 100 RPM

Test Method 
We used a Brookfield DV3TLV Rheometer with LV guard leg and Rheocalc™ software for automated instrument control and data acquisition. The sample, tested in a 600 mL low form Griffin Beaker, was immersed in a TC-502P Programmable Refrigerated Bath and equilibrated at 25°C. Representative data from the analyses in Figure 2 show a relatively constant viscosity at 25°C of approximately 52 cP over the speed range tested.
