1.1 This test method covers the laboratory determination of the viscosity of oils at 150oC and 1 X 106s-1 and at 100oC and 1 X 10 6s-1, using high shear rate tapered-plug viscometer models BE/C or BS/C.
1.2 Newtonian calibration oils are used to adjust the working gap and for calibration of the apparatus. These calibration oils cover a range from approximately 1.8 to 5.9 mPa-s (cP) at 150oC and 4.2 to 18.9 mPa-s (cP) at 100oC. This test method should not be used for extrapolation to higher viscosities than those of the Newtonian calibration oils used for calibration of the apparatus. If it is so used, the precision statement will no longer apply.
1.3 A non-Newtonian reference oil is used to check that the working conditions are correct. The exact viscosity appropriate to each batch of this oil is established by testing on a number of instruments in different laboratories. The agreed value for this reference oil may be obtained from the chairman of the Coordinating European Council (CEC) Surveillance Group for CEC L-36-A90, or from the distributor.
1.4 Applicability to products other than engine oils has not been determined in preparing this test method.
1.5 This test method uses the millipascal seconds, mPa-s, as the unit of viscosity. For information, the equivalent cgs unit, centipoise, cP, is shown in parentheses.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
