This standard specifies a method for the measurement of emulsification asphalt viscosity by the Engra Viscometer, where the Engra viscosity is expressed as the Engra degree E. During the test, the ratio of the time required for the sample to flow 50 mL out of the Engra Viscometer at 25 ° C to the time required for the same amount of distillation water to flow out. The sample flow should be in a continuous linear shape. Instruments and materials include the Engra Viscometer, stopwatch, pipette, reagents, etc., to ensure the accuracy and repeatability of the test.
