Applicant's summary and conclusion

Conclusions:
The visocity of the test material at 100 C was determined to be 12.5 cSt and 131.6 cSt at 40 C
Executive summary:

The viscosity of the test substance was determined according to ASTM D445-97 Standard Test Method for Kinematic Viscosity of Transparent and Opaque liquids (the Calculation of Dynamic Viscosity). Viscosities were measured at two temperatures:

Viscosity at 100 deg. C is 12.5 cSt

Viscosity at 40 deg. C is 131.6 cSt
