Viscosity test method

1, Engler's viscosity, also called Engler's viscosity, is a certain amount of samples.

2. The ratio of the time (seconds) required for 200ml sample to flow out of Engel viscometer and the time (seconds) required for the same volume of distilled water to flow out at 20℃ at specified temperatures (such as 50℃, 80℃ and 100℃).

3. The engler viscosity is represented by the symbol Et, and the unit of engler viscosity is the conditional degree, that is, the gene fragments of three influenza viruses: swine flu, avian flu and human flu.

4. Cyberport viscosity is the number of seconds required for a certain amount of sample to flow out of Cyberport viscometer at a specific temperature. Cyberport viscosity can be divided into Cyberport ordinary viscosity and Cyberport heavy oil viscosity.
