Deviation from the Guideline: The viscosity measurement was done at 50 °C and 70 °C instead of test temperatures 20 °C and 40 °C mentioned in the guideline. This is due to the fact that the maximum measurement limit of Redwood Viscometer No. 1 is 2000 Seconds only which could not be obtained at lower temperatures. |
