Asphalt Standard Viscometer
Application and Usage of the Asphalt Standard Viscometer:
According to the industry standard set by the Ministry of Communications
T0621
The specification outlines how to determine the viscosity of liquid petroleum asphalt, coal pitch, and emulsified asphalt in a flowing state. It is suitable for measuring the viscosity of viscous petroleum asphalt, liquid petroleum asphalt, and soft coal tar pitch with low consistency. The viscosity is measured as the time it takes for the sample to flow through the drain hole of the standard viscometer at a specified temperature.

Indicates the viscosity measurement, which is used to classify the sample.
How to Use the Asphalt Standard Viscometer:
Before use, check that all parts are functioning properly. Ensure the water tank is clean and free of obstructions in the oil tank hole. Follow these steps for testing.
1. Fill the water injection funnel, making sure the water does not exceed the engraved line.
2. Remove the oil sump cover.
3. Select the appropriate diameter of the oil drain hole based on the test asphalt's specifications and markings.
4. Use a metal lever to block the drain hole.
5. Take the asphalt sample, melt it, and pour it into the oil tank.
6. Cover the oil cup.
