It is made of relevant standards-ASTM D1200-2010《 Standard Test Method for Viscosity by F0rd Viscosity Cup》.
The correction coefficient value “K” is the time after the filling of the viscosity cup with the secondary standard oil under the set temperature conditions (such as 20 °C ± 0.1 °C), the flow time should be in the range of 30s ~ 100s, the K value should be 1 ± Within 0.03 range. The viscometer should be periodically calibrated to the extent of its frequency of use.
4 Viscosity Cup belongs to laboratory, workshop, control and test instruments. The measured viscosity is conditional viscosity. Namely: a certain amount of sample, at a certain temperature, from the prescribed diameter of the hole flow out of time.
